I haven't tried opencode, but when I opened pi I was able to complain about that silly and stupid left-padding that LLM TUIs have started using that prevents basic copy-paste operation, and pi was able to edit itself to fix it.

So I'm sold on that level alone. Good stuff.

They are different models. OpenCode is trying to be a claude code/codex replacement, where-as pi is something you build yourself, kind of trying to be an emacs type thing compared to vs-code. As in emacs it is more common to write your own extensions, where as in vs-code most people just download them.

oh-my-pi is a bit of a cross between the two; comes with basically everything OpenCode does, but still easy to customise.

OpenCode is nice if you don't want to do a lot of research and just want to get started right away. The OpenCode Go plan for $5 a month for your first month is a great way to do this, with good models to choose from and reasonable usage limits for a beginner.

I like it.

One caveat is that it doesn't do MCP tools, but can wire them up with bash (or use CLIs if those are available).
