Can you use OpenRouter with this?
and pay 5% commission? no thanks.
There's also https://aihubmix.com/ that does it at cost

Also litellm

Doesn't seem to be at cost, there's a markup on the input and output tokens. At least for their Anthropic endpoints.
Google ones appear up be at cost. Maybe they do markup on specific ones.

If you're all in on Claude then yeah, just go direct. Going through a proxy of silly

Well it's not silly if the proxy has higher rate limits.
Early when sonnet 3.5 was the best coding model lots of people used them because of the rate limits on anthropic's own API. So that's a plus. There's also the ease of use, one key for every model out there, and you get to choose providers for things like deepseek / qwen / llama if those suit your needs.
That doesn’t sound bad, for extra redundancy?
Yes at onboarding asks for gemini and openrouter keys
Yes, you can bring OpenRouter or any other provider and connect directly! (We don't route your messages through a backend like others).
Why no linux build? It is just vscode in ts right? And it is an electron app right?
There's a link for Linux at the bottom of the download page, which directs to the releases in GitHub
Ah sorry, I see that now. It was just really small.
We do have a linux build! (the link is at the bottom of the download page). Some systems are a bit finicky so we give more options on setting it up.
I gave it a go. Was having issues installing the AppImage, which is my preferred method, but extracting the .tar.gz (or the .deb) eventually worked.
they always start as open source to bait users. how long until this one also turns into BaitWare? I hope it won't since it's backed by Y Combinator and has an Apache 2 license.
>how long until this one also turns into BaitWare?

>VSCode Fork.

Already did. Can't wait to hear their super special very important reason why this can't exist as an extension.

The best reason I‘ve seen mentioned by the founder in this thread, is showing/hiding panels, and the onboarding flow. Those are things you can’t do with a plugin. I personally also like Cursor‘s diff view way better than Continue‘s, and maybe that’s because a fork gives more control there.
(Edit: the parent comment was edited to add "I hope it won't since it's backed by Y Combinator and has an Apache 2 license." - that's a good redirection, and I probably wouldn't have posted a mod reply if the comment had had that originally.)

(Btw if your comment already has replies, it is good to add "Edit:" or something if you're changing it in a way that will alter the context of replies.)

They first need to substantially grow the user base as we saw with OpenWebUI, only then make an Enterprise offering and switch the license from one day to another.
I've got a great setup going with Emacs and Aidermacs[1]. I just can't stand using VS Code, it's impossible to configure to my liking.

[1]: https://github.com/MatthewZMD/aidermacs

what sorts of things are hard to configure?
Emacs' configurability is hard to describe to anyone who hasn't immersed themselves in that sort of environment. There's a small portion of the program written C, but the bulk of it is written in elisp. When you evaluate elisp code, you're not in some sandboxed extension system - you're at the same level as Emacs itself. This allows you to modify nearly any aspect of Emacs.

It'd be a security nightmare if it was more popular, but fortunately the community hovers around being big enough for serious work to be done but small enough that it's not worth writing malware for.

I don't think it's a security nightmare per-se. Most of the time, you're not installing a lot of packages (the built-in are extensive) and most of these are small and commonly used.

It's like saying the AUR is a security nightmare. You're just expected to be an adult and vet what you're using.

I'm not sure I agree with the number and size of packages people install (unless you're comparing them to, say, org-mode), but that's not really what I'm talking about.

Emacs runs all elisp code as if it's part of Emacs. Think about what Emacs is capable of, and compare that to what a browser allows its extensions to do. No widely used software works like that because it's way too easy to abuse. Emacs gets away with it because it's not widely used.

I don't know the first thing about VSCode but I'm willing to bet there are strict limits to what its plugins are allowed to do.

I don't know if that's changed since last I wrote an extension for a web browser, but the API is pretty open for the current context (tab) that it's executing in. As long as it's part of the API, the action is doable. Same with VSCode or Sublime. Sandboxed plugins would be pretty useless.
I don't know if it's a security nightmare any more than other editors that have "plugins" (or the like).

One advantage for Emacs is it's both easy and common read the code of the plugins you are using. I can't tell you the last time I looked at the source code of a plugin for VS Code or any other editor. The last time I looked at the code for a plugin in Emacs was today.

That last line was totally unexpected, yet deeply familiar. Took over a minute to recover from that rofl.
My setup: vim -> ctrl + z -> claude -> ctrl + c -> fg
it's a shame vim is so stinky because after 15 years of using it now i find myself using vscode. I always like vim because editing is efficient. Now I dont write as much as supervise a lot of the boilerplate code.

Over the years I have gotten better with vim, added phpactor and other tooling, but frankly i dont have time to futz and its not so polished. With VSCode I can just work. I don't love everything about it, but it works well enough with copilot i forgot the benefits of vim.

I get your experience, but for me using vim is perfect for code exploration. The only needed plugins are fzf.vim and vinegar. The first for fuzzy navigation and the second for quickly browsing the current directory.

LSP experience with VSCode may be superior, but if I truly needed that, I would get an IDE and have proper intellisense. The LSP in Vim and Emacs is more than enough for my basic requirements, which are auto-imports, basic linting, and autocomplete to avoid misspellings. VSCode lacks Vim's agility and Emacs's powerful text tooling, and do far worse on integration.

I created an OSS ai coding platform as well: https://brokk.ai

But it's a different take, Brokk is built to let humans supervise AI more effectively rather than optimizing for humans reading and writing code by hand. So it's not a VS Code fork, it's not really an IDE in the traditional sense at all.

Intro video with demo here: https://www.youtube.com/watch?v=Pw92v-uN5xI

Watched your Youtube. I love this - will try it out and give it to our team. This is effectively the "full mode" version of the mode I currently use Cursor for.
Can it run in a GitHub action ?

What I want is to be able to do is.

1. Create a branch called TaskForLLM_123 2. Add a file with text instructions called Instructions_TaskForLLM_123.txt 3. Have a GitHub action read the branch, perform the task and then submit a PR.

I’ve seen people do this with Claude Code to great success (not in a GH Action). Even multiple sessions concurrently. Token budget is the limit, obviously.
worktree + pr support is coming soon, in the meantime you gotta do it manually
Is there some benefit from forking vscode instead of creating an extension?
People keep saying that the extensions API is too limited or something, but Cline seems to manage fine with being an extension.
You're right that extensions do manage fine - the main differences right now are UX improvements (many of them are mentioned above). I can see the differences compounding at some point which is why we're focused on the full IDE side.
It gets them more slop funding if they can say they have an “AI IDE”.
well you got downvoted, but it's not wrong: funding attractiveness of an extension (Cline) vs your "own IDE".
Of course I got downvoted (but it’s gone back to four now) because this is HN, where somehow a group of otherwise seemingly intelligent people are all patting themselves on the back about the latest Y Combinator AI slop funding.
As an (ex) VSCode extension developer, VSCode really does lock down what you can do as an extension. It's well intentioned and likely led to the success of VSCode, but it's not great if you want to build entirely new UI interactions. For instance, something like the cmd-k inline generation UI in Cursor is basically impossible as a VSCode extension.
Maybe someone should just fork VS Code in a more liberal way, then everyone can build their extensions on top of that.
The restrictive extension ecosystem was a big part of VSCode's success. You can compare to Atom, which allowed extensions to do whatever they wanted: Atom ended up feeling exceptionally slow and bloated because extensions had full latitude to grind your IDE to a halt.
Yeah, I don't have a problem with that!

But since there seems to be a need for AI-powered forks of VS Code, it could make sense for them all to build off the same fork, rather than making their own.

Isn’t that what they’re doing by building off of vscode?
Yup, just rebased about a week ago
Ask Firefox how that went.

Hint: they dropped XUL because every update broke extensions

That's not comparable though, right? I'm suggesting a third party forks the main product.
Worse. The result is the same: an unmaintainable product, and now you also become increasingly incompatible with the source.
One of the big _disadvantages_ is that it prevents access to the VSCode-licensed plugins, such as the good C# LSP (seems EEE isn't completely dead). That's something to pay attention to if you're considering a fork and use an affected language.
Since these products supposedly make developers 1000x more productive it should be no problem to just re-implement those proprietary MS plugins from scratch. Right? Any volunteers...?
MS will be tuning Copilot to the point it’s the best agent for C#, for sure. It might take a little longer ofc. But Nadella mentioned to Zuck in a fireside chat that they are not happy with C# support in LLMs and that they are working on this.
C# language server, being Roslyn Language Server, is plugin agnostic, it's MIT licensed and is essentially a part of the compiler: https://github.com/dotnet/roslyn/tree/main/src/LanguageServe....

Did you mean to say a debugger? That one has an open alternative (NetCoreDbg) alongside a C# extension fork which uses it (it's also what VS Codium would install). It's also what you'd use via DAP with Neovim, Emacs, etc.

Nope, OmniSharp - which uses that AFAIK, is what I'm referring to. Something being open source doesn't automatically make it good.
Omnisharp is what the base C# extension used previously. It has been replaced by Roslyn LS (although can be switched to back still). You are talking about something you have no up-to-date knowledge of.

Void dev here! As others have mentioned, VSCode strongly limits the functionality that you can build as an extension. A few things we've built that aren't supported as an extension: - the Accept|Reject UI and UX - Cmd+K - Control over the terminal and tabs - Custom autocomplete - Smaller things like ability to open/close the sidebar, onboarding, etc

It's been a lot harder to build an IDE than an extension, but we think having full control over the IDE (whether that's VSCode or something else we build in the future) will be important in the long run, especially when the next iteration of tool-use LLMs comes out (having native control over Git, the UI/UX around switching between iterations, etc).

the Accept|Reject UI and UX , Continue as a VS Code extension also seems to manage this
>Smaller things like ability to open/close the sidebar

Are you sure about this one? I'm sure I have used an extension whose whole purpose was to automatically open or close the sidebar under certain conditions.

(comment deleted)
I wish all these companies the best and I understand why they’re forking, but personally I really don’t want my main IDE maintained by a startup, especially as a fork. I use Cursor, and I’ve run into a number of bugs at the IDE level that have nothing to do with the AI features. I imagine this is only going to get worse over time.
Any particular reason why they forked VSCode and not Theia?
Nobody uses Theia, relatively speaking.
This sounds like exactly the kind of thing Theia would be useful for. It's easier than a straight up fork of VSCode.

Would you please stop posting like this?

We're trying for thoughtful, respectful discussion of people's work on this site. Snarky, nasty oneliners destroy that.

We detached this subthread from https://news.ycombinator.com/item?id=43928512.

Apologies for the snark, you're correct.

But I do stand by the point. We are seeing umpteen of these things launched every week now, all with the exact same goal in mind; monetizing a thin layer of abstraction between code repos and model providers, to lock enterprises in and sell out as quickly as possible. None of them are proposing anything new or unique above the half dozen open source extensions out there that have gained real community support and are pushing the capabilities forward. Anyone who actually uses agentic coding tools professionally knows that Windsurf is a joke compared to Cline, and that there is no good reason whatsoever for them to have forked. This just poisons the well further for folks who haven't used one yet.

Yes, the high-order bit is to avoid snark, so thanks about that. And it's clear that you know about this space and have good information and thoughts to contribute—great!

I would still push back on this:

> all with the exact same goal in mind

It seems to me that you're assuming too much about other people's intentions, jumping beyond what you can possibly know. When people do that to reduce things to a cynical endstate before they've gotten off the ground, that's not good for discussion or community. This is part of the reason why we have guidelines like these in https://news.ycombinator.com/newsguidelines.html:

"Please don't post shallow dismissals, especially of other people's work. A good critical comment teaches us something."

"Please respond to the strongest plausible interpretation of what someone says, not a weaker one that's easier to criticize. Assume good faith."

"Don't be curmudgeonly. Thoughtful criticism is fine, but please don't be rigidly or generically negative."

I'll take my paddling. Thanks for the work you do here btw, truthfully.

Oh wow this is nice, will try it out.

Ycombinator backed too I guess Vibe coding is here to stay

> Ycombinator backed too

Oh wow, I didn't even realize. Substantially less appealing of a project to me now.

I just gave zed a try after trying it a few months ago and it's come along way, not a bad non-cursor chat AI IDE. Its tracking mode is pretty cool
VSCode death by a thousand forks.
It feels like everyone and their mother is building coding agents these days. Curious how this compares to others like Cline, VS Code Copilot's Agent mode, Roo Code, Kilo Code, Zed, etc. Not to mention those that are closed source, CLI based, etc. Any standout features?
My 2c: I rarely need agent mode. As an older engineer, I usually know what exactly needs to be done and have no problem describing to the LLM what to do to solve what I'm aiming to do. Agent mode seems its more for novice developers who are unsure what tasks need to be broken down and the strategy that they are then solved.
"Novice mode" has always been true for the newcomer. When I was new, I really was at the mercy of:

1) Authority (whatever a prominent evangelist developer was peddling)

2) The book I was following as a guide

3) The tutorial I was following as a guide

4) The consensus of the crowd at the time

5) Whatever worked (SO, brute force, whatever library, whatever magic)

It took a long ass time before I got to throw all five of those things out (throw the map away). At the moment, #5 on that list is AI (whatever works). It's a Rite of Passage, and because so much of being a developer involves autodidacticism, this is a valley you must go through. Even so, it's pretty cool when you make it out of that valley (you can do whatever you want without any anxiety about is this the right path?). You are never fearful or lost in the valley(s) for the most part afterward.

If you use AI agents for all your work as a novice do you ever make it out of the valley?
Yeah.

Most people have not deployed enough critical code that was mostly written with AI. It's when that stuff breaks, and they have to debug it with AI, that's when they'll have to contend with the blood, sweat, and tears. That's when the person will swear that they'll never use AI again. The thing is, we can never not use AI ever again. So, this is the trial by fire where many will figure out the depth of the valley and emerge from it with all the lessons. I can only speculate, but I suspect the lessons will be something along the lines of "some things should use less AI than others".

I think it's a cool journey, best of luck to the AI-first crowd, you will learn lessons the rest of us are not brave enough to embark on. I already have a basket of lessons, so I travel differently through the valley (hint: My ship still has a helm).

> that's when they'll have to contend with the blood, sweat, and tears.

Or, most software will become immutable. You'll just replace it.

You'll throw away the mess, and let a newer LLM build a better version in a couple of days. You ask the LLM to write down the specs for the newer version based on the old code.

If that is true, then the crowd that is not brave enough to do AI-first will just be left behind.

If that is true, then the crowd that is not brave enough to do AI-first will just be left behind.

Not even, devoured might be more apt. If I'm manually moving through this valley and a flood is coming through, those who are sticking automatic propellers and navigation systems on their ship are going to be the ones that can surf the flood and come out of the valley. We don't know, this is literally the adventure. I'm personally on the side of a hybrid approach. It's fun as hell, best of luck to everyone.

It's in poor taste to bring up this example, but I'll mention it as softly as I can. There were some people that went down looking for the Titanic recently. It could have worked, you know what I mean? These are risks we all take.

Quoting the Admiral from Starcraft Broodwars cinematic (I'm a learned person):

"... You must go into this with both eyes open"

> It's in poor taste to bring up this example, but I'll mention it as softly as I can. There were some people that went down looking for the Titanic recently. It could have worked, you know what I mean?

Not sure if you drew the right conclusion from that one.

The scenario you paint sounds very implausible for non-trivial applications, but even if it ends up becoming the development paradigm, I doubt anyone will be "left behind" as such. People will have time to re-skill. The question is whether some will ever want to or would prefer to take up woodworking.
Whether one takes up woodworking or not depends on whether or not development was primarily for profit, with little to not intrinsic enjoyment of the role.
Coding and woodworking are similiar from my perspective, they are both creative arts. I like coding in different lanuages, woodworking is simply a physical manifestion of such. In a world where you only need agents, is not a world where nerds will be employed. Traditional nerds cant stand out from the crowd anymore.

This is peak AI, it only goes downhill from here in terms of quality, the AI first flows will be replaceable. Those offshored teams that we have suffered with for years now will be primarly replaced (google first programmers). And developers will continue, working around the edges. The differences will be that startups wont be able to use technology horading to stifle competition, unless they make themselves immune from the ai vacumes.

I can appreciate the comments further up around how AI can help unravel the mysterys of a legacy codebase. Being able to ask questions about code in quick succession will mean that we will feel more confident. AI is lossy, hard to direct, yet very confident always. We have 10k line functions in our legacy code that nests and nest. How confident are you to let ai go and refactor this code without oversight and ship to a customer? Thus far im not, maybe i dont know the best model and tools to use and how to apply them, but even if one of those logic branches gets hallucinated im in for a very bumpy ride. Watching non-technical people at my org get frusted and stuck with it in a loop is a lot more common then the successes which seem to be the opposite of the experienced engineers who use it as a tool, not a savour. But every situation is different.

If you think you company can be a differentiator in the market because it has access to the same AI tool as every other company? We'll well see about that. I believe there has to be more.

Im an experienced engineer of 30+yrs. Technology comes and goes. AI is just a another tool in the chest. I use it primarily because i dont have to deal with ads. I also use it to be a electrical engineer, designing circuts in areas i am not familiar with. I can see very simply the noivce side of the coin, it feels like you have super powers because you just dont know enough about the subject to be aware of anything else. Its sped up the learning cycle considerably beacause of the conversational nature. After a few years of projects, i know how to ask better questions to get better results.

> Or, most software will become immutable. You'll just replace it.

The joys of dependency hell combined with rapid deprecation of the underlying tooling.

Slaves to the system.

Do we really want that? To be beholden to the hands of a few?

Hell, you can't even purchase a GPU with high enough VRAM these days for an acceptable amount of money. In part because of geopolitics. I wonder how many morerestrictions are there to come.

There's a lot of FOMO going around, those honing their programming skills will continue to thrive, and that's a guarantee. Don't become a vassal when you can be a king.

Just... WAT.

That's like saying "I'll just burn down my house because I can replace it. Anyone who repairs their house will be left behind."

It's true, you can replace it, so I can't put my finger on what has been stopping people from burning their houses down instead of, say, spring cleaning

  > that's when they'll have to contend with the blood, sweat, and tears. That's when the person will swear that they'll never use AI again. 
sounds like me after my first hangover...
What leads you to believe non-AI coding is over?

I'm not using AI and I'm still an incredibly high velocity engineer because I own my codebase. I've written each line ten times over, like a player who has become highly skilled at one particular game.

Same here. It’s fine for me to use the ChatGPT web interface and switch between it and my IDE/editor.

Context switching is not the bottleneck. I actually like to go away from the IDE/keyboard to think through problems in a different environment (so a voice version of chatgpt that I can talk to via my smartwatch while walking and see some answers either on my smartglasses or via sound would be ideal… I don’t really need more screen (monitor) time)

I use voice mode of ChatGPT almost exclusively using RayBan metaglasses(especially when outside / cyciling).
You would like to, or you're actually doing that right now?
> Same here. It’s fine for me to use the ChatGPT web interface and switch between it and my IDE/editor.

I do this all the time, and I am completely fine with it. Sure, I need to pay more attention, but I think it does more good than harm.

Sorry to say but this workflow just isn't great unless you're working on something where AI models aren't that helpful -- obscure language/libraries/etc where they hallucinate or write non-idiomatic solutions if left to run much by themselves. In that case, you want the strong human review loop that comes from crafting the context via copy paste and inspecting the results before copying back.

For well trodden paths that AI is good at, you're wasting a ton of time copying context and lint/typechecking/test results and copying back edits. You could probably double your productivity by having an agentic coding workflow in the background doing stuff that's easy while you manually focus on harder problems, or just managing two agents that are working on easy code.

I’m a senior engineer and I find myself using agents all the time. Working on huge codebases or experimenting with different languages and technologies makes everybody “novice”.
Can you give some examples of how you use it? I'm used to asking for very specific things, but less so full on agent mode.
Agent mode seems to be better at realizing all the places in the code base that need to be updated, particularly if the feature touches 5+ files, whereas editor starts to struggle with features that touch 2-3 files. "every 60 ticks, predict which items should get cached based on user direction of travel, then fetch, transform and cache them. when new items need to be drawn, check the cache first and draw from there, otherwise fetch and transform on demand." this touches the core engine, user movement, file operations, graphics etc and agent mode seems to have no problem with this at all.
Personally, I’ve found agents to be a great “multitasking” tool.

Let’s say I make a few changes in the code that will require changes or additions to tests. I give the agent the test command I want it to run and the files to read, and let it cycle between running tests and modifying files.

While it’s doing that, I open Slack or do whatever else I need to do.

After a few minutes, I come back, review the agent’s changes, fix anything that needs to be fixed or give it further instructions, and move to the next thing.

I think a good use of time while waiting for an LLM is to ask another LLM for something. Until then Slack will do :)
One benefit is when working on multiple code bases where the size of the code base is larger than the time spent working on it, so there is still a gap of knowledge. Agents don't guarantee the correctness of a search the same an old search field does, but it offers a much more expressive way to do searches and queries in a code base.

Now that I think about it, I might have only ever used agents for searching and answering questions, not for producing code. Perhaps I don't trust the AI to build a good enough structure, so while I'll use AI, it is one file at a time sort of interaction where I see every change it makes. I should probably try out one of these agent based models for a throw away project just to get more anecdotes to base my opinion on.

kind of ironic, because the novices are the ones that absolutely should be doing things by hand to get better at the craft.
The day will come when only a few need to be "better at the craft". Just as with Assembly and even C.
C is still in the top 5 most used languages by any metric.
no one writes assembly, but good engineers still understand how things work under the hood
I dont agree. I use agents all the time. I say exactly what the agent should do but often changes need to be made in more than one place in the code base. Could I prompt it for every change one at a time per file? Sure, but it is faster do prompt an agent for it.
Considering that Agent Mode saves me a lot of hassle doing refactoring ("move the handler to file X and review imports", "check where this constant is used and replace it with <another> for <these cases>", etc.), I'd say you are missing the point...

I actually flip things - I do the breakdown myself in a SPEC.md file and then have the agent work through it. Markdown checklists work great, and the agent can usually update/expand them as it goes.

I couldn't use AI code without agentic mode.

At it's most basic, agentic mode is necessary for building the proper context. While I might know the solution at the high level, I need the agent to explore the code base to find things I reference and bring them into context before writing code.

Agentic mode is also super helpful for getting LLMs from "99%" correct code to "100%" correct code. I'll ask them to do something to verify their work. This is often when the agent realizes it hallucinated a method name or used a directionally correct, but wrong column name.

(comment deleted)
My main interest in agent mode is deputizing the C++ compiler to tell the LLM about everything it has hallucinated.
I think this perspective is better characterized as “solo” and not “old”. I don’t think your age is relevant here.

Senior engineers are not necessarily old but have the experience to delegate manageable tasks to peers including juniors and collaborate with stakeholders. They’re part of an organization by definition. They’re senior to their peers in terms of experience or knowledge, not age.

Agentic AIs slot into this pattern easily.

If you are a solo dev you may not find this valuable. If you are a senior then you probably do.

20yrs engineer here, all my life I've dreamed of having something that I could ask general questions about a codebase to and get back a cohesive, useful answer. And that future is now.
I would put it more generic. I love that one can now ask as many dumb questions as it takes about anything.

With humans there is this point where even the most patient teacher has to move on to do other things. Learning is best when one is curios about something and curiosity is more often specific. (When generic one can just read the manual)

The difference is this one is backed by Y Combinator.
Does this mean "open source" is really "market capture before becoming closed-source"?
I've been at many open source meetups with YC founders and can tell you that this is not the thinking at all. Rather, the emphasis is on finding a good carve-line between the open source offering and the (eventual) paid one, so that both sides are viable and can thrive.

Most common these days is to make the paid product be a hosted version of the open source software, but there are other ways too. Experienced founders emphasize to new startups how important it is to get this right and to keep your open source community happy.

No one I've heard is treating open source like a bait and switch; quite the opposite. What is sought is a win-win where each component (open source and paid) does better because of the other.

Exactly right.

I think there’s a general misconception out there that open sourcing will cannibalize your hosted product business if you make it too easy to run. But in practice, there’s not a lot of overlap between people who want to self-host and people who want cloud. Most people who want cloud still want it even if they can self-host with a single command.

Void has been around since last year.

I'm working on an agnostic unified framework to make contexts transferrable between these tools.

This will permit zero friction, zero interruption transitions without any code modification.

Should have something to show by next week.

Hit me up if you're interested in working on this problem - I'm tired of cowboying my projects.

Yup - honestly the space is so open right now still, everyone is trying haha. It's got quite hard to keep track of different models and their strengths / weaknesses, much less the IDE and editor space! I have no idea which of these AI editors would suite me best and a new one comes out like every day.

I'm still in vim with copilot and know I'm missing out. Anyway I'm also adding to the problem as I've got my own too (don't we all?!), at https://codeplusequalsai.com. Coded in vim 'cause I can't decide on an editor!

This is cool! I like that you have a visual element for the agent working on multiple tickets at a time.
Thanks! And yeah, it really is satisfying watching the tickets move from column to column "all on their own" as the works gets done!
The weird thing is, the biggest reason I don't use Cursor much is because they just distribute this AppImage, which doesn't install or add itself to the Ubuntu app menu, it just sits there and I have to do

    sudo chmod 755 path/to/Cursor-0.48.6.x86_64.AppImage
    path/to/Cursor-0.48.6.x86_64.AppImage
and then I get greeted with an error message:

    The setuid sandbox is not running as root. Common causes:

I have to go Googling, then realize I have to run it with

    bin/appimage/Cursor-0.48.6-x86_64.AppImage --no-sandbox
Often I'm lazy to do all of this and just use the Claude / ChatGPT web version and paste code back and forth to VS code.

The effort required to start Cursor is the reason I don't use it much. VS code is an actual, bona fide installed app with an icon that sits on my screen, I just click it to launch it. So much easier. Even if I have to write code manually.

[flagged]
Not only did you mess up the formatting, but you pasted a very lengthy code, generated by an LLM. Perhaps consider using a pastebin in the future, if at all.

AppImageLauncher improves the AppImage experience a lot, including making sure they get added to the menu. I'm not sure if it makes launching without the sandbox easier or not.
Coding agents are the future and it's anyone's game right now.

The main reason I think there is such a proliferation is it's not clear what the best interface to coding agents will be. Is it in Slack and Linear? Is it on the CLI? Is it a web interface with a code editor? Is it VS Code or Zed?

Just like everyone has their favored IDE, in a few years time, I think everyone will have their favored interaction pattern for coding agents.

Product managers might like Devin because they don't need to setup an environment. Software engineers might still prefer Cursor because they want to edit the code and run tests on their own.

Cursor has a concept of a shadow workspace and I think we're going to see this across all coding agents. You kick off an async task in whatever IDE you use and it presents the results of the agent in an easy to review way a bit later.

As for Void, I think being open source is valuable on it's own. My understanding is Microsoft could enforce license restrictions at some point down the road to make Cursor difficult to use with certain extensions.

Another YC backed open source VS Code is Continue: https://www.continue.dev/

(Caveat: I am a YC founder building in this space: https://www.engines.dev/)

Void dev here! The biggest players in AI code today are full IDEs, not just extensions, and we think that's because they simply feel better to use by having more control over the UX.

There are certainly a lot of alternatives that are plugins(!), but our differentiation right now is being a full open source IDE and having all the features you get out of the big players (quick edits, agent mode, autocomplete, checkpoints).

Surprisingly, all of the big IDEs today (Cursor/Windsurf/Copilot) send your messages through their backend whenever you send a message, and there is no open source full IDE alternative (besides Void). Your connection to providers is direct with Void, and it's a lot easier to spin up your own models/providers and host locally or use whatever provider you want.

We're planning on building Git branching for agents in the next iteration when LLMs are more independent, and controlling the full IDE experience for that will be really important. I worry plugins will struggle.

The versioning and git branching sounds really neat, I think! Can you say more about that? Curious if you've looked at/are considering using Jujutsu/JJ[0] in addition or instead of git for this, I've played with it some, but been considering trying it more with new AI coding stuff, it feels like it could be a more natural fit than actually creating explicit commits for every change, while still tracking them all? Just a thought!

[0]https://github.com/jj-vcs/jj

I agree the branching sounds super cool!
If you're open to something CLI-based, my project Plandex[1] offers git-based branching (and granular versioning) for AI coding. It also has a sandbox (also built on git) that keeps cumulative changes separate from project files until they're ready to apply.

1 - https://github.com/plandex-ai/plandex

Interesting, thanks for sharing! We planned on spinning up a new Git branch and shallow Git clone (or possibly worktree/something more optimized) for each agent, and also adding a small auto-merge-with-LLM flow, although something more granular like this might feel better. If we don't use a versioning tool like JJ at first (may just use Git for simplicity at first), we will certainly consider it later on, or might end up building our own.
Isn't continue.dev also open source and not using 'their backend' when sending stuff? I didn't use it in a while, but I know it had support for llama, local models for tab completions, etc.
Continue is doing great work, but they're an extension (plugin)!
What’s wrong with a plugin? I don’t see the benefit of an IDE over a plugin.
The extensions API lets you control the sidebar, but you basically don't have control over anything in the editor. We wouldn't have been able to build our inline edit feature, or our navigation UI if we were an extension.
Continue.dev is an extension and it does inline edits just fine in VS Code and IntelliJ.
Is inline edits the same as diff edits? In that case I think Cline and Roo can do it as well.
If I understand your question correctly - Cline and Roo both display diffs by using built-in VS Code components, while Cursor/Windsurf/Void have built their own custom UI to display diffs. Very small detail, and just a matter of preference.
It's about whether the tool can edit just a few lines of the file, or whether it needs to stream the whole file every time - in effect, editing the whole file even though the end result may differ by just a few lines.

I think editing just a part of the file is what Roo calls diff editing, and I'm asking if this is what the person above means by line edits.

Big fan of Continue btw! There's a small difference in how we handle inline edits - if you've used inline edits in Cursor/Windsurf/Void you'll notice that a box appears above the text you are selecting, and you can type inside of it. This isn't possible with VS Code extensions alone (you _have_ to type into the sidebar).
So this is closer to Zed than Cursor/Windsurf/Continue, right?

edit: ahh just saw that it is also a fork of VS Code, so it is indeed OSS Cursor

Yep, Void is a VSCode fork, but we're definitely not wed to VSCode! Building our own IDE/browser-port is not out of the picture. We'll have to see where the next iteration of tool-use agents takes us, but we strongly feel writing typescript/rust/react is not the endgame when describing algorithms to a computer, and a text-based editor might not be ideal in 10 years, or even 2.
I think it'd be worthwhile to call out in a FAQ/comparison table specifically how something like an "AI powered IDE" such as Cursor/Void differs from just using an IDE + a full-featured agentic plugin (VS Codium + Cline).
I agree, having used Cline I am not sure what advantages this would offer, but I would like to know (beyond things like “it’s got an open source ide” - Cline has those too specifically because I can use it in my open source ide)
> The biggest players in AI code today are full IDEs, not just extensions,

Claude Code (neither IDE nor extension) is rapidly gaining ground, it's biggest current limitation being cost, which is likely to get resolved sooner rather than later (Gemini Code anyone?). You're right about the right now, but with the pace at which things are moving, the trends are honestly more relevant than the status quo.

> Claude Code (neither IDE nor extension) is rapidly gaining ground

What makes you say that? From what I’m observing it doesn’t seem to be talked much about at all.

Claude Code's announcement earned 2k+ point on HN when it launched (7th most popular HN submission this year).

https://hn.algolia.com/?q=claude+code

Together with 3.7 Sonnet. And the claim was that it is rapidly gaining ground, not that it sparked initial interest. I still don’t see much proof of adoption. This is actually the first I’ve heard about anyone actually actively using it since its launch.
>This is actually the first I’ve heard about anyone actually actively using it

I've been reaching for Claude Code first for the last couple weeks. They had offered me a $40 credit after I tried it and didn't really use it, maybe 6 weeks ago, but since I've been using it a lot. I've spent that credit and another $30, and it's REALLY good. One thing I like about Claude Code is you can "/init" and it will create a "CLAUDE.md" that saves off it's understanding of the code, and then you can modify it to give it some working knowledge.

I've also tried Codex with OpenAI and o4-mini, and it works very well too, though I have had it crash on me which claude has not.

I did try Codex with Gemini 2.5 Pro Preview, but it is really weird. It seems to not be able to do any editing, it'll say "You need to make these edits to this file (and describe high level fixes) and then come back when you're done and I'll tell you the edits to do to this other file." So that integration doesn't seem to be complete. I had high hopes because of the reviews of the new 2.5 Pro.

I also tried some claude-like use in the AI panel in Zed yesterday, and made a lot of good progress, it seemed to work pretty well, but then at some point it zeroed out a couple files. I think I might have reached a token limit, it was saying "110K out of 200K" but then something else said "120K" and I wonder if that confused it. With Codex you can compact the history, I didn't see that in Zed. Then at some point my Zed switched from editing to needing me to accept every change. I used nearly the entire trial Zed allowance yesterday asking it to impelement a Galaga-inspired game, with varying success.

Spending too much time on HN and other spaces (including offline) where people talk about what they're doing. Making LLM-based things has also been my job since pretty much the original release of GPT3.5 which kicked off the whole industry, so I have an excuse.

The big giveaway is that everyone who has tried it agrees that it's clearly the best agentic coding tool out there. The very few who change back to whatever they were using before (whether IDE fork, extension or terminal agent), do so because of the costs.

Relevant post on the front page right now: A flat pricing subscription for Claude Code [0]. The comment section supports the above as well.

I personally tried it and I felt it way more confusing to use compared to using Cursor with Claude 3.7 Sonnet. The CLI interface seems to me more to lend itself for «vibe coding» where you actually never work and look with the actual code. That is why I think Cursor and IDEs are more popular than CLI only tools.
Just want to share our thinking on terminal-based tools!

We think in 1-2 years people will write code at a systems level, not a function level, and it's not clear to us that you can do that with text. Text-based tools like Claude Code work in our text-based-code systems today, but I think describing algorithms to a computer in the future might involve more diagrams, and terminal will not be ideal. That's our reasoning against building a tool in the terminal, but it clearly works well today, and is the simplest way for the labs to train/run terminal tool-use agents.

Diagrams are great at providing a simplified view of things but they suck ass when it comes to providing details.

There's a reason why fully creating systems from them died 20 years ago - and it wasn't just because the code gen failed. Finding a bug in your spec when its a mess of arrows and connections can be nigh impossible.

Go image search "complex unreal blueprint".

This is completely true, and it's a really common objection.

I don't imagine people will want to fully visualize codebases in a giant unified diagram, but I find it hard to imagine that we won't have digests and overviews that at least stray from plaintext in some way.

I think there are a lot of unexplored ways of using AI to create an intelligent overview of a repo and its data structures, or a React project and its components and state, etc.

Terminals aren't too far away from evolving [0] beyond UTF-8 characters. Therefore I suspect IDEs and CLIs will continue their turf wars as always.

> hard to imagine that we won't have digests and overviews

100% agreed here.

Sounds exactly like what DeepWiki is doing from the Devin AI Agent guys: https://deepwiki.com

You have lost all connection to reality.

Hey by the way I hear all communication between people is going to shift to pictograms soon. You know -- emoji and hieroglyphs. Text just isn't ideal, you know

Every system can be translated can be translated to text though. If there is one thing LLMs have essentially always been good at, it is processing written language.
I don't know Claude Code, so if it's "neither IDE nor extension", what is it?
I think it's worth mentioning that the Theia IDE is a fully open source VS Code-compatible IDE (not a fork of VS Code) that's actively adding AI features with a focus on transparency and hackability.
We considered Theia, and even building our own IDE, but obviously VSCode is just the most popular. Theia might be a good play if Microsoft gets more aggressive about VSCode forks, although it's not clear to us that people will be spending their time writing code in 1-2 years. Chances are definitely not 0 that we end up moving away from VSCode as things progress.
It's the most popular because the tech is decades old. You're all rushing to copy obsolete technology. Now we have 10 copies of an obsolete technology.

We used to know better

I mean I guess I should thank the 10 teams who forked VSCode for proving beyond all reasonable doubt that VSCode is architecturally obsolete. I was already trying to make that argument, but the 10 forks do it so much better.
> and there is no open source full IDE alternative (besides Void).

And Zed: https://zed.dev

Yesterday on the front page of HN:

https://news.ycombinator.com/item?id=43912844

And Emacs, also mentioned in that thread (by me, but still).
this joke could not have been more perfectly set up if it were staged. thanks for the guffaw.
I should have been more careful with my wording - I was talking about major VS Code-based IDEs as alternatives. Zed is very impressive, and we've been following them since before Void's launch!
openAI chose to acquire windsurf for 3B instead of building something like Void, very curious decision. awesome project, will be closely following this
>> The biggest players in AI code today are full IDEs, not just extensions

Are you sure? I have some expertise with my IDE, some other extension which solve problems for me, a wide range of them, I've learnt shortcuts, troubleshooting, where and who ask for help, but now you're telling me that I am better off leaving all that behind, and it's better for me? ;o

Maybe I live in a bubble, but it's surprising to me that nobody mentions Jetbrains in all these discussions. Which in my professional working experience are the only IDEs anyone uses :shrug:
I’m not sure I’ve met a Jetbrains user in projects I’ve worked on. It’s a paid product so just has a small userbase.
Pycharm is extremely popular in the data science world. The Community Edition is free and has 99% of the features most people need. Even when developing with Cursor, I find myself going back to Pycharm just to use the debugger, which I greatly prefer to the debugger used in these VS Code forks.
Funny enough, I know a lot of people who work at JetBrains, but only a few end-users.

Their use base is completely different. And we’re both in a bubble, I reckon. IntelliJ people also only know a few VSCode users!

Here are some numbers on their user base in real number and dollar amounts: https://www.jetbrains.com/lp/annualreport-2024/

Their tools are wildly popular in many spaces. It isn't for everyone though. It's totally believable in your circle no one uses their tools, but it isn't niche.

You forgot the best one to compare against - Claude Code.
We think terminal tools like Claude Code are a good way for research teams to experiment with tool use (obviously pure text), but definitely don't see the terminal as the endgame for these tools.

I know some folks like using the terminal, but if you like Claude Code you should consider plugging your API key into Void and using Claude there! Same exact model and provider and price, but with a UI around the tool calls, checkpoints, etc.

I’m a traditional millennial brat - high preference for UI as well.

That is until I started using Claude Code.

It’s not about the terminal. It’s just a better UX in general.

I've tried many of AI coding IDE's, the best ones like RooCode are good simply because they don't gimp your context. The modern day models are already more then capable enough for many coding tasks, you just need to leave them alone and let them utilize their full context window and all will go well. If you hear a bad experience with any of these IDE's, most of the time its because its limiting use of context or improper management of related functions.
> It feels like everyone and their mother is building coding agents these days.

For real. I think it's because code editors seem to be in that perfect intersection of:

- A tool for programmers. Programmers like building for programmers.

- A tool for productivity. Companies will pay for productivity.

- A tool that's clearly AI-able. VC's will invest in AI tools.

- A tool with plenty of open source lift. The clear, common (and extreme?) example of this being forking VSCode.

Add to that the recent purchase of VSCode-fork [1] Windsurf for $3 billion [2] and I suspect we will see many more of these.

This is very cool and I'm always happy to see more competition in this space. That said, two suggestions:

- The logo looks like it was inspired directly from the Cursor logo and modified slightly. I would suggest changing it.

- It might be wise to brand yourself as your own thing, not just an "open source Cursor". I tend to have the expectation that "open source [X]" projects are worse than "[X]". Probably unfair, I know.

A minor counterpoint, I personally like the "open source Xyz" because I instantly know what the product is supposed to do. It's also very SEO friendly because you don't know the name of the open source version before you find it, so you can Kagi/Google/DDG "open source Cursor" and get it as a top result, instead of a sea of spammy slime.
> I personally like the "open source Xyz" because I instantly know what the product is supposed to do.

But that assumes that you're already familiar with the non-open-source software referenced. I've never used Cursor so I have no idea what it can or can't do. I'm pretty sure I would never have discovered Inkscape if it had consistently been described as an “open-source Illustrator” as I've simply never used Adobe software.

Thanks for the suggestions - these issues have been a bit painful for us, and we will probably fix them in the next major update to Void.

Believe it or not, the logo similarity was actually unintentional, though I imagine there was subconscious bias at play (we created ours trying to illustrate "a slice of the Void").

Maybe the icon is a piece of cake with a sphere void in it? Trying to play on how easy it is - ‘it’s a piece of cake’
I don't know anything about the project, I use Zed editor, but I think the logo is really cool.
If I move off Cursor, it's def not going to be to another vs-code derivative. Zed has it right - build it from the ground up, otherwise, MS is going to kneecap you at some point.
The threat is Msft cutting you off from the ecosystem. That means growing an ecosystem and not merely the editor.
Great to see more people thinking this way, finally. Would be even better to see the same change wrt typescript, another MS trojan horse.
100%. Microsoft can't interfere with Zed.

Additionally, Zed is written in Rust and has robust hardware-accelerated rendering. This has a tangible feel that other editors do not. It feels just so smooth, unlike clunky heavyweight JetBrains products. And it feels solid and sturdy, unlike VS Code buffers, which feel like creaky webviews.

Zed didn't build from the ground up though. I mean, they did for a lot of stuff, but crucially they decided to rely on the LSP ecosystem so most of the investment in improving Zed is also a direct investment in improving VSCode.

If you can't invest in yourself without making the same size investment in your competitor, you probably have no path to actually win out over that competitor.

I’ve been using Claude coder, I like this exp way more than these ai ides way more.
I subscribed to the mailing list of void long ago to be notified once the alpha opens, but i've never recieved anything. I forgot about it until today.
We've been holding off on this until Void is out of Beta.
(comment deleted)
The time to sell a VSCode fork for 3B was a week ago. If someone wants to move off of VSCode, why would they move to a fork of it instead of to Zed, JetBrains, or a return to the terminal?

Next big sale is going to be something like "Chrome Fork + AI + integrated inter-app MCP". Brave is eh, Arc is being left to die on its own, and Firefox is... doing nothing.

This is realy cool and checks my privacy boxes, great name too. I will be testing it out and will consider contributing.

One thing i'd really like to have is a manual order for folders or even files in the explorer view.

Nice - also open competition is always good for users!
Mandatory reminder that "agentic coding" works way worse than just using the LLM directly, steering it ad needed, filling the gaps, and so forth. The value is in the semantical capabilities of the LLM itself: wrapping it will make it more convenient to use, but always less powerful.
I beg to disagree, Salvatore... Have a go at VS Code with Agent mode turned on (you'll need a paid plan to use Claude and/or Gemini, I think). It gets me out of vim, so yeah, it's that good. :)

Tip: Write a SPEC.md file first. Ask the LLM to ask _you_ about what might be missing from the spec, and once you "agree" ask it to update the SPEC.md or create a TODO.md.

Then iterate on the code. Ask it to implement one of the features, hand-tune and ask it to check things against the SPEC.md and update both files as needed.

Works great for me, especially when refactoring--the SPEC.md grounds Claude enough for it not to go off-road. Gemini is a bit more random...

Interacting with the LLM directly is more work. What I mean is that a wrapper in the best conditions will not damage too much the quality of the LLM itself. In the chat, you continuously avoid suboptimal choices executed by the model, if you are a very experienced code, and a fix here, a fix there, you continuously avoid local minima. After a few iterations you find that your whole project is a lot better designed than otherwise.
Oh, sure. I don't rely on the LLM to write all the code. I do "trust" it to refactor things to a shape I want, and to automate chores like moving chunks of code around or build a quick wrapper for a library.

One thing I particularly don't like about LLMs is that their Python code feels like Java cosplay (full of pointless classes and methods), so my SPEC.md usually has a section on code style right at the start :)

Another one? People saw that 3B windsurf money.
