Happier is an open-source, end-to-end encrypted companion app for AI coding agents:
Claude Code, Codex, OpenCode, Cursor, Pi, Grok, Gemini, Copilot, Qwen, Kimi, Kilo, Kiro, Auggie.
Run sessions on your computer, and continue them from your phone.
Use our desktop app or web app, and truly start working from anywhere.
YOUR EXISTING SESSIONS? ALREADY THERE.
Open any Claude Code, Codex or OpenCode session running on your computer — live, from your phone. Nothing to migrate, nothing to learn.

REVIEW THE DIFF. SEND NOTES TO YOUR AGENTS.
Browse every line your agent changed.…
