I guess the logic here is: If I love this project, I should renew my JetBrains subscription...so that they can keep having money to fix bugs in their IDE...so that you can keep reverse engineering it?
I know this exact comment is probably becoming tedious on HN, but it's very rare that a tool I pay for is so bad I'll jump ship for 0.1.0 alpha if a clone
If you do a lookup at WIPO brands database you can find "intellij" and "intellij idea" owned by Jetbrains s.r.o. but not "idea" alone.
Based on this only a judge can decide if it is close enough to be an infringement and could misled customers. Given the readme days eplicitely says it is not the same IDE as Intellij IDEA I would say it would be hard to convince someone customers are misled.
Interesting project. It seems it uses CodeMirror [1] in the Tauri frontend (60% of total code is typescript), but uses rust in the backend (30%). Surprising to see that Tauri is apparently good enough for the three platforms it needs to support (or it uses a lot of hacks, I don't know). The advertised memory reduction is remarkable as I expected a full web view to be a bit memory heavy. Not sure how this IDE keeps up with large documents or a lot of opened views though.
Even at 60 MB, assuming the app is on the order of "hello world", that's almost two orders of magnitude more overhead than Win32 on my x64 Windows 11 box (tested with C, assume Rust with the windows crate would be similar).
The only value adding vibe coded software I've used so far has been clones of existing software that can then be used for free since now it's in a legal greyzone and you can pretend it's not piracy...all thanks to subsidized subscriptions enabled by companies who are in part the publishers of the software that is being cloned. What a time to be alive...
Where Rust scores over Go is not so much on the speed but memory usage. As memory is becoming expensive (and likely to stay for sometime), the appeal for Rust increases.
The large disk space usage for Rust is much more solvable than speed-up in Rust compilation as long as crate remains the lowest compilation unit.
Barring this, even for AI based development Golang is much better language. But Rust's long term payoff is too good at this point.
Also try Lapce! In my experience somehow starts noticably faster even than Zed. Also implemented in Rust but different GUI approach. Both support LSPs.
How did Hacker News become the place where you announce a hack and all the comments are like "I don't like this because I feel it might be in a legal gray area"?
>but does it makes any sense without feature parity?
The entire project makes no sense. Names itself Open when IDEA is already open, says built in Rust when 60% is TS, says it's native app when it's a web app with a native connection, clueless benchmarks, made by vibe coders who don't even use/need an IDE, ...
Uses Typescript for the most part, not much better than Electron stuff, cannot use the InteliJ plugins powered by the JVM, it is vibe coded, no thanks.
Calling it "OpenIDEA" is a bit misleading. IntellijIDEA is free and open source (Apache 2.0) since 2009. Paid subscription basically gives you extra plugins. And as others pointed out, saying that it was rebuilt in Rust is at least as much misleading: the code processing is still standalone LSP processes, frontend is WebView with typescript, only Tauri glue code is Rust. And that in turn makes me extremely skeptical about claimed memory usage! Consider that you must compare idea.exe against combo of WebView (on windows: chromium edge) + LSP (for Java, likely Eclipse LSP, at least that's what VSCode traditionally uses for Java). Is it realistic to fit that in claimed 169 MB?
Correction: Rust is more than just Tauri glue code. But considering that in an IDE the two performance critical parts are code processing (LSP) and frontend, I wonder how much benefit can you really get by making everything except of them in Rust.
Except people forget that only works for VScode, thanks to the multiple processes architecture with enough components written in a mix of C++, Rust, .NET and Java, with the terminal using WebGL.
It is quite telling how many clueless folks brag about Java support in VSCode, without understanding that depending on the plugin, they are either running Eclipse or Netbeans headless.
Yeah, Electron works, provided one creates a whole circus around its performance issues.
Eclipse was an ide that needed a supercomputer to run on an early version of Java when it first came out.
It was interesting, but sluggish.
Jetbrains took advantage of it for profit and eventually adobe'd the business model, although granted they made a lot of improvements for various languages.
I have no pity for companies who made money off open source and lose it the same way. But this looks like a fight between fighters past their prime.

Am I seeing this right?
Which isn't the vibe I want from my editor.

looks inside
60% Typescript
Yeah, didn't think so...
Building consistent frontends for all platforms isn’t easy in rust, so they use web standards for that.
Rust at home:

1. The editor implementation is here: <https://github.com/l0ng-ai/openidea/blob/main/src/editor/cor...>
> completion from language servers
That's exactly the thing that I like about idea: It's better than that.
IDEA is much smarter than what a language server alone offers.
I bet it's a lot of fun being a Rust programmer / coder.
The large disk space usage for Rust is much more solvable than speed-up in Rust compilation as long as crate remains the lowest compilation unit.

Since when cloning an open source project became a "hack" ?
In the benchmark[1] the cpu, memory and quit time (!) are compared, but does it makes any sense without feature parity?

I hear this a lot, the argument usually being "they didn't care to put effort into it, so it probably won't be maintained.
It's basically the Lindy effect: The longer something has existed, the longer it probably will.
https://en.wikipedia.org/wiki/Lindy_effect
But maybe as a measure of effort rather than time. Commits no longer mean effort since the computer can just make commits on its own.
Still, if I saw a vibe coded project and the guy had been maintaining it for ten years (someday!), that gives a different feeling.
It is still the output of a replicator machine, regardless of text, images, video or code.
I'm not sure exactly why this came to mind. Vibes?

What are they doing now? crisis of ideas and just hyping? pity.
