Going cross platform doesn’t sound the main reason (or I hope not). For a company that size, is it really hard to hire specialised small team?! It would be a good show case for their Codex too

They presumably use codex to build this. LLMs output is non-deterministic. Harder to keep the same logic across.

Would I love the, use swiftui on macos, wpf/winui om windows, whatever qt hell it is on linux? Sure

But it is what it is.

I am glad the codex-cli is rust and native. Because claude code and opencode are not: react, solidjs and what have you for a tree layer.

Then again, if codex builds codex, let it cook and port if AI is great. Otherwise, it’s claim chowder

It is hard because this product will likely be obsolete next year based on how quickly AI is changing and evolving. Speed is king when you're on the frontier
