A Remote Control for Your AI Coding Agent

What it does Happy wraps the official Claude Code and Codex CLI tools so you can run an agent session on your computer and steer it from an iOS, Android, or web client. When you open the app, the session restarts in remote mode so you can check progress, grant permissions, or handle errors from across the room. End-to-end encryption keeps your code between your devices, and control returns to your desktop as soon as you press any key.

The interesting bit Rather than reinventing the agent, Happy acts as a stateful proxy that hands off the terminal session to your phone and takes it back when you return. It is essentially glue code with a security layer, built by engineers who wanted to peek at their side projects during coffee breaks without leaving their laptops unlocked.

Key highlights

• End-to-end encrypted sync; the server never sees unencrypted code
• Push notifications when the agent needs permission or encounters an error
• Open source, no telemetry, no tracking
• Mobile and web clients built with Expo
• 22,414 stars and a pair of app store releases

Verdict Grab it if you run long agent sessions and want to step away without losing oversight. Skip it if you do not use Claude Code or Codex, or if your desk chair has grown roots.
