For Claude Code usersCodex usersTeams sharing agent sessions
- Before
- You walk back to your computer to check the terminal, and each agent lives in its own window with its own login.
- After
- You see every session in one desktop app and on your phone, reply from either, and the work keeps running when you close the window.

Overview
Happy is an open-source app for running coding agents such as Claude Code, Codex and Grok in one place, using the subscriptions you already pay for. The desktop app for macOS, Windows and Linux finds the sign-ins on your machine, keeps sessions running after you close the window, and pairs with the Happy phone app so you can follow and steer the same sessions away from your desk. A built-in Chief of Staff bot walks you through setup in plain conversation. It suits people who already use one of these coding agents.
It adds no model bill of its own: it reuses your existing agent sign-ins, and traffic between your devices is end-to-end encrypted.

Features
From the creator's documentation.
| Feature | What it does | Runs |
|---|---|---|
| Many agents | Claude Code, Codex, Grok, and Gemini through Antigravity, in one app | Your existing plans |
| Durable sessions | Sessions keep running after the window closes or the computer restarts | Your computer |
| Phone app | The same sessions on iPhone and Android, end-to-end encrypted in transit | Relay server |
| Workspaces | Parallel work gets its own Git worktree on its own branch | Your computer |
| Auto mode | Reads and workspace edits run freely; other actions are sandboxed | Your computer |
| Multiplayer | A team server lets colleagues share projects and sessions | Team server |
Good to know
You start a Claude Code or Codex task at your desk and want to keep an eye on it from your phone. Happy runs the sessions in its desktop app and shows the same ones in its phone app, where you can read progress and send the next message.
Limits
- It needs a coding agent already signed in on the computer; Happy does not supply model access. Voice in the phone app has a monthly free allowance, then an in-app subscription.
- New sessions run in Auto mode, where reads and workspace edits happen without asking. Start with a small change in a project you can undo.
