Codex is pretty good, and it is written in Rust.
Codex does not go well with my Zellij/Alacritty setup. It does not respect resize events. Opencode is nice, though
5.4 is smarter than Opus when it comes to really figuring out a problem. Codex agentic stuff takes forever though.
Something being written in rust has no bearing to whether it’s good. You can create slop in any language.

So?
I’m a big fan of Rust, but the frontend being written in Rust doesn’t help a ton with backend issues unfortunately.
