Codepet is notarized by Apple, so this is just a one-time confirmation — no “unidentified developer” warning.

Before you start

Codepet runs its AI work on your own Claude Code, not on our servers — your code and your company never leave your machine, and there is no usage bill from us. That means you need Claude Code installed and signed in, plus Node.js. Without them the app still opens and tells you what is missing.

Codepet is currently available for macOS only. Windows and other platforms are on the roadmap.
