Happy: Codex & Claude Code App
An independent phone companion for coding-agent sessions running on your own computer.
Consider it for supervising an existing authorised desktop setup.
Mobile prompts, permission responses and diffs allow continuity away from the desk.
Keep in mind: It requires Happy Desktop/CLI and separate access to the desired agent provider; it is not endorsed by OpenAI or Anthropic.

Privacy & permissions
