Happier: Claude Codex OpenCode

Code anywhere. Faster. Happier

Free · Designed for iPad

**Happier** is an open-source, end-to-end encrypted app that brings the power of Claude Code, Codex, Gemini, and OpenCode to your pocket. **Happier** is an open-source, end-to-end encrypted companion app for AI coding agents. It takes the power of Claude Code, Codex, Gemini, and OpenCode and lets you run sessions on your computer, and continue them from your phone — including collaboration, reliable resume, and full history access. Whether you’re on a train through the Alps or grabbing a coffee, Happier ensures your AI coding sessions never skip a beat. **Important**: This app requires the Happier CLI and at least one supported provider (Claude Code, Codex, Gemini, OpenCode) installed on your computer. The iOS app acts as a secure bridge between your local development environment and your mobile device. ### Why "Happier"? Happier started as a fork of **Happy**. We were using Happy daily for work and loved the concept, but we needed faster iteration, stronger reliability, and a set of features that weren’t available yet. After weeks of building and refining, we are sharing it so others can try it and help shape what comes next. Happier lets you **build** anything you want—with friends. We’ve rebuilt the foundation to support more models, more platforms, and more ways to work together. ### Features: * **Collaborative sessions:** share a session with teammates & friends (private or public links). * **Broad provider support:** works with Claude Code, Codex, Gemini, OpenCode, and more (configurable). * **Persistent sessions:** resume sessions even after restarts; archive and return later. * **Seamless switching:** move between terminal, web UI, and mobile while keeping context. * **Subscriptions or API keys:** use your existing Claude Pro/Codex/Gemini subscriptions, or configure API keys in-app. * **Infinite history:** scroll back through older messages in long sessions. * **Pending queue:** edit/reorder queued messages before the agent processes them. * **tmux support:** resume remote-started sessions locally (Claude). ### Security & privacy * **End-to-End Encryption**: built using the same encryption as Signal (TweetNaCl) * **Zero-Knowledge**: your code is encrypted on your machine before it ever hits the wire. We cannot read your data. Your encryption keys never leave your devices. * **Built in Switzerland:** developed in Switzerland, with a strong focus on data protection and developer transparency. ### How It Works: 1. Install the `happier-cli` on your Mac, Linux, or PC. 2. Pair your device instantly with a secure QR code. 3. Start a session (e.g., `happier claude` or `happier codex`). 4. Code solo, or invite a friend to jump into the session with you. ### Community-Driven **Happier** is completely open-source. We built this because we wanted a more powerful, more social way to interact with AI agents - and we want to build it in the open, shaped by the people who actually use it. This project exists because we needed it ourselves - and we want it to evolve through real feedback. We aim to keep the community welcoming and contributor-friendly, whether you’re signaling an issue or proposing a larger idea. What that means in practice: * **Open development** and transparent discussions * **Fast feedback loops** on issues and pull requests * A focus on **solving real developer pain**, not chasing hype If something feels broken, missing, or awkward - we want to hear about it. Happier grows through shared experience and collaboration. **Code faster. Code together. Be Happier.** Not affiliated with or endorsed by Anthropic, OpenAI, or Google.
