About

Happy is a free, open-source app for running Claude, Codex and Grok in one place, each with its own vendor prompts and tools. It signs in with the subscriptions the user already has rather than adding a new bill. Sessions are available on a mobile app with end-to-end encrypted sync, and a colleague can join a session to watch and steer the same agent. The original CLI wraps Claude Code and Codex in the terminal and lets the user continue from a phone.

Use cases: coding, code-generation, agent-orchestration
