Show HN: 1Code – Open-source Cursor-like UI for Claude Code (github.com)
Here's a video of the product: https://www.youtube.com/watch?v=Sgk9Z-nAjC0
Claude Code has been our go-to for 4 months. When Opus 4.5 dropped, parallel agents stopped needing so much babysitting. We started trusting it with more: building features end to end, adding tests, refactors. Stuff you'd normally hand off to a developer. We started running 3-4 at once. Then the CLI became annoying: too many terminals, hard to track what's where, diffs scattered everywhere.
So we built 1Code.dev, an app to run your Claude Code agents in parallel that works on Mac and Web. On Mac: run locally, with or without worktrees. On Web: run in remote sandboxes with live previews of your app, mobile included, so you can check on agents from anywhere. Running multiple Claude Codes in parallel dramatically sped up how we build features.
What’s next: Bug bot for identifying issues based on your changes; QA Agent, that checks that new features don't break anything; Adding OpenCode, Codex, other models and coding agents. API for starting Claude Codes in remote sandboxes.
Try it out! We're open-source, so you can just bun build it. If you want something hosted, Pro ($20/mo) gives you web with live browser previews hosted on remote sandboxes. We’re also working on API access for running Claude Code sessions programmatically.
We'd love to hear your feedback!

Also a better link is: https://1code.dev/
The repo doesn't have screenshots, so you might loose traffic just because of that.
Nevertheless, I'll try it out - looks nice!
I’m all for new, better tools and will probably test this out over the weekend to see if the interface is more usable than Claude’s. Just curious if there’s anything you’re particularly excited about compared to the official release.
So we decided to build a tool that WE would actually use, and once we succeeded with that, we open-sourced it. Since then we've received a lot of feedback on where to take this product - some use cases Anthropic will probably never do, like integrating Codex or adding other z.ai GLM subscription.
We're just trying to ship something we use ourselves, and maybe it could be useful to others, and see where it goes.
>Yes, 1Code works with your Claude Pro or Max subscription. Sign in with your Anthropic account and use your existing subscription. We charge separately for the 1Code app.
Is this even after the recent events; Anthropic banning 3rd-party access to the Claude Pro/Max subscriptions and only allowing API access? Tool is nice but most certainly not* 800$ nice.
*Based on heavy Claude Max users here, the people that will be running 3-4 agents, saying API would've cost them $1k+.

And a "max" subscription for $200/m??? It makes no sense. It's not because LLM making companies have plans at $200 that any company should make a $200/m plan.
If you really want a 'different' UI thats unlike VSCode or Cursor already, I'd genuinely recommend checking out almost any other tool that pairs with CC.

nothing specifically against vscode/electron/atom. i did use atom 10 years ago, then started sublime text 2, since then, it has been really hard to beat sublime text. the speed and rendering of sublime is much better.
i also have been using zed, which can be considered cloud-code ui too in certain terms, zed is quite more resource-intensive than the sublime and feels higher latency. (possibly because I use frosty-transparent theme...)
- not only is it much more performant but also mobile friendly
I may be missing something in my setup, but I find these things happening in all Claude wrappers I have tried.
1. After a long stint of planning or back and forth exchange, I have to scroll to find the bottom of the conversation. Same with Claude itself.
2. I don’t want tabs as much as I want split window’s that I can label and highlight.
3. The more calm it is, I feel like I’m going to miss something that it’s fucking up. Sometimes in normal CC, I will look over and it’s making a large assumption and nuking a change we just made. I would love to control the verbosity or at least be able to peak behind the curtain at certain points.
4. I like the click flow for the planning Q&A but it wasn’t clear if I could add my own answer like I can in CC.
Other than these, I like it and want to use it more so than my current daily driver CLIManager. (Which has the overlap with points 1 and 2)
Nice work overall!
On point 4 (custom answers in Q&A): You're right, this is missing! I'll add the ability to write your own answers today or tomorrow.
On point 1 (scrolling): I pushed a batch of scroll fixes yesterday, but I see it's still not working optimally. We're actively working on improving this - it's definitely on our radar.
On point 2 (split windows): We're planning to add multi-window support soon - so you can have multiple chat windows open side by side, similar to how you'd work with multiple terminal windows, but with a nice UI. Stay tuned!
On point 3 (verbosity control): Great suggestion - sometimes you want to catch assumptions before they cause damage. Adding to our roadmap.
Thanks again, and glad you're finding it useful despite these rough edges!
It's cool first time I see it I say NO WAY!!!
LOVE IT SO MUCH
