subzer0

an open-source ai app that can rewrite itself.

you open it, and meet the basic ui. dont like it? REWRITE IT. ask the ai to change the ui of the app, and it does that. "make the ui purple" and it makes it purple.

no api keys, no model downloads. it drives opencode, the coding agent on your machine, and uses every model opencode can see — free, opencode go, or metered. it also updates itself in the background.

download the windows setup — unzip, run subzer0 Setup.exe, done.
