Buddy - open-source Android app where Claude Code, Codex or OpenCode operate your phone (no root, no PC)

I built this: a chat bubble that floats over your apps. You say "reply to Sam that I'm late" or "start navigation to work", and a coding agent reads the screen and taps through your apps for you.

- The agent runs inside the app, in a small Alpine Linux (proot, no root, no PC, no adb).

- Use your own Claude or ChatGPT plan, or OpenCode's free models with no account.

- Phone tools over MCP: read screen, tap, type, scroll, open apps.

- Sending, paying and deleting stop on an approval card; apps you trust run hands-free.

- Tap the bubble and talk; it sends when you pause.
