OpenAI Codex CLI: Lightweight coding agent that runs in your terminal

Fingers crossed for this to work well! Claude Code is pretty excellent.

I’m actually legitimately surprised how good it is, since other coding agents I’ve used before have mostly been a letdown, which made me only use Claude in direct change prompting with Zed (“implement xyz here”, “rewrite this function with abc”, etc), so very hands-on.

So I’ve went into trying out Claude Code rather pessimistically, and now I’m using it all the time! Sure, it ends up costing a bunch, but it’s easy to justify $15 for a prompting session if the end result is a mostly complete PR, done much faster.

All that is to say - competition is good, fingers crossed for codex!

too expensive. I cant understand why everyone is into claude code vs using claude in cursor or windsurf.

If you have AWS credits...
