What is Happy?

Happy lets you start coding agent sessions on your computer and continue them from your phone or the web. This repository holds the mobile app for iOS, Android and the web, the original CLI and the relay server; the desktop app and the agent runtime live in separate repositories. You sign in with the Claude, Codex or Grok subscriptions you already pay for, and Happy adds a harness rather than another bill. Everything that moves between your devices is end-to-end encrypted, and projects stay ordinary folders on your own hardware.

Good fit if

  • You run long agent tasks and want to check on them away from your desk.
  • You already pay for Claude or Codex and do not want another subscription.

Look elsewhere if

  • You want a desktop orchestrator for many agents at once: Orca.
  • You want a self-hosted control center for a team: OpenHands.

Before you adopt it

Happy is MIT-licensed. Every commit in the last 90 days came from a single developer, so the project depends on one person.
