How does it work?

On your computer, run happy instead of claude to start the normal Claude Code UI through our wrapper. When you want to control Claude from your phone, it restarts the session in remote mode. To switch back to your computer, just press any key on your keyboard.

🏠 Who We Are

We're engineers scattered across Bay Area coffee shops and hacker houses, constantly checking how Claude is progressing on our pet projects during lunch breaks. Happy Coder was born from the frustration of not being able to peek at Claude building our side hustles while we're away from our keyboards. We believe the best tools come from scratching your own itch and sharing with the community.
