Happy Next is a mobile companion for Claude Code, Codex, and Gemini CLI. It lets you monitor and control your AI coding sessions from anywhere — your phone, tablet, or another computer.

​
Why Happy Next?

AI coding agents run long tasks. You shouldn’t have to sit at your desk watching them. Happy gives you:
  • Mobile control — Send instructions, approve permissions, and review code from your phone
  • Real-time sync — See what your agent is doing right now, across all your devices
  • Voice control — Talk to your AI agent instead of typing
  • Multi-agent support — Claude Code, Codex, and Gemini in one place
  • End-to-end encryption — Your code and conversations are encrypted before leaving your device. We can’t read them.
  • Task orchestration — Dispatch multi-agent workflows with dependency graphs
