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!

Claude Code has a closed license https://github.com/anthropics/claude-code/blob/main/LICENSE....

There is fork named Anon Kode https://github.com/dnakov/anon-kode which can use more models and non-Anthropic ones. But the license is unclear for it.

It's interesting to see codex to be Apache License. Maybe somebody extends it to be usable with competing models.

In terms of terminal-based and open-source, I think aider is the most popular one.
