About

Happy, also known as Happy Coder, is a free, open source mobile and web client that lets users spawn, view, and control multiple Claude Code AI coding agent sessions on any device, phone, tablet, laptop, or desktop, by syncing them in real time using an encrypted relay architecture so that a session started on one device can be continued seamlessly on another without losing context. It comprises three coordinated components, a CLI program that runs locally to launch and monitor Claude Code, a mobile app or web app that connects securely to the CLI session using end-to-end encryption so nobody (including the relay server) can read your data, and a relay server that simply passes encrypted blobs between devices without access to the contents; this design lets developers maintain their existing tools, editors, and workflows while adding remote control capability.

About

port22 puts your coding agents in your pocket. Run the agent, pair your iPhone, and drive Claude Code, Codex, or OpenCode from anywhere while reading the live transcript and approving actions as the agent works. It attaches to the session already running in your terminal rather than starting or forking a new one, so you can continue working with the same live process you began at your desk. Every token is streamed to your phone as the agent thinks, edits, and runs, while push notifications arrive when it finishes or needs your approval. Live status remains visible through the Dynamic Island and lock screen, so you can follow every active session without repeatedly opening the app. port22 works over your local network at your desk and automatically switches to an end-to-end encrypted relay when you leave Wi-Fi, keeping the same session over cellular.
