It still bothers me that almost every agentic TUI is written in TS + React. It often consumes at least a few GB of RAM. No one bothers about it. Everybody is trying to ship as fast as possible.

I highly recommend Crush which is built with Go

The UX is definitely better because it uses the bubble tea library which is probably the best TUI framework ever

And you can use a ton of different providers and models

Ram is cheap, 99.9% of the audience that would use this are running heavy envs on powerful computers. I can totally understand why they write it that way. Better to have faster iteration and alienate 0.1% of serious users than to slow development just to cater to them.

Well, it's not only about RAM. Things like calculating correct diffs take more time too, but it's hidden.

Again, the pro/con ratio pays off.

They use react on a cli tool?

Yes, the library is @vadimdemedes/ink, which uses React to render components

Well codex is written in rust.

Interesting, the ink repo still states that codex is using it:

    Who's Using Ink?

    Codex - An agentic coding tool made by OpenAI.

I guess they had initial versions written in TS?

UPD. They switched 3 months ago.

Where did you get React from?

You can decompile it, but it's pretty well known that it uses TypeScript, React, and Ink. Same for gemini, codex and others.

Codex got ported to Rust

Why would they?
