Happy is an open‑source desktop and mobile client that lets you control Claude Code, Codex and Grok agents from any device. It provides a unified UI, CLI and encrypted sync for collaborative AI‑assisted coding.
Use cases
- Control Claude Code or Codex agents from my laptop while traveling
- Collaborate in real‑time with a teammate on the same AI coding session
- Switch between multiple AI models (Claude, Codex, Grok) within a single workflow
- Run the Happy CLI to script interactions with coding agents from the terminal
- Use the mobile app to continue a coding session securely on my phone
- Leverage my existing subscription plans without paying for a new service
When to choose
- You need a cross‑platform GUI and CLI to interact with multiple LLM coding agents
- You want end‑to‑end encrypted sync between desktop and mobile devices
- You prefer an open‑source solution that runs locally on your hardware
When to avoid
- You require a fully self‑hosted server‑only API without any GUI components
- Your workflow depends on a specific proprietary AI platform not supported by Happy
- You need deep customisation of the underlying AI models beyond what the client offers
