Description

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. Terms of Use: https://www.apple.com/legal/internet-services/itunes/dev/stdeula/

Reviews

  • This app is insane

    5
    By NotACommonReviewer
    As you can see from my nickname, I really only do 5 or 1 star reviews when I leave written feedback. This one goes for 5. I know Claude launched remote controller Claude sessions. I’ve tried it. It’s not close to this. At least not yet. The DX and the amount of things you can set your workflow up to do and leverage Happy is absolutely cracked. And the mobile app experience is incredibly user friendly being able to intuitively take the Claude/codex response context and auto suggest clickable response options even outside of the ones Claude itself asks (I think). Please keep this app going for as long as possible.

    It’s great! I like it more than antigravity and Vs code for sure!
  • Way too complicated

    Sorry but the setup is not even remotely easygoing. This is just not made for me.
  • Great Agent Tool

    Have really enjoyed using this with Claude Code - it’s genius! Biggest improvement I’d suggest is to update codex support to include recent models (5.3)
  • Codex no

    The app seems really well designed and I’m sure it works great for Claude but I cannot for the life of me figure out how to get conversation parody with codex. I seem to be getting stuck on a permission screen where the Happy app does not accept my answer to the permission request clicking the option directly in the UI
  • Too many bugs left

    There are many bugs discussed in github issues but left unsolved, it's better to find other stable ways.
  • Incredibly intuitive and easy

    I’ve tried a few other ways to interact remotely with Claude Code and have even built my own. Happy is by far the most intuitive and smoothest way to communicate with Claude code
  • Buggy

    Permissions is currently broken. Otherwise the app is very interesting and promising
