About Happy: Codex & Claude Code AppStorefront description supplied by Apple.
Happy Coder is the secure mobile companion for Codex and Claude Code that lets you continue your AI coding sessions anywhere (not affiliated with Anthropic or OpenAI). Built by developers who needed to check on their AI assistant's progress during coffee breaks, this app brings the full Codex and Claude Code experience to your phone with military-grade encryption.
**Important**: This app requires Codex or Claude Code to be installed on your computer. Happy Coder is a companion app that connects to your existing Codex or Claude Code setup.
**Key Features:**
- Continue Codex and Claude Code sessions seamlessly between desktop and mobile
- Push notifications for permission requests and task completion
- Access conversation history even when your terminal is offline
- End-to-end encryption - your code stays private
- Real-time streaming of AI responses
- Zero-knowledge architecture - we can't read your data
**How It Works:**
1. Install the happy-coder CLI on your computer
2. Scan a QR code to securely pair your devices
3. Use 'happy' instead of 'codex' or 'claude' to start encrypted sessions
4. Switch between desktop and mobile instantly
Perfect for developers who:
- Want to monitor long-running tasks on the go
- Need secure access to proprietary code discussions
- Value privacy and open-source transparency
- Work from coffee shops, trains, or anywhere
Happy Coder uses the same encryption as Signal (TweetNaCl) and is completely open source. Your encryption keys never leave your device, and all data is encrypted before transmission.
Built by Bay Area engineers who believe the best tools come from scratching your own itch. We needed a way to securely check on our AI coding assistant while away from our desks - so we built it and shared it with the community.
Your code. Your privacy. Your Codex and Claude Code companion.
