Claude Code, Codex, OpenCode, Pi and more, working together and in parallel on your own machines.
Sessions can spawn subagents across agents: e.g. Claude asking Codex for a review, or Codex delegating work to Claude subagents. Switch agents mid-session. Approve, steer, review and commit from wherever you are.

Latest Happier project update
The desktop app is the recommended way in: it sets up the CLI and the daemon for you.
macOS/Linux:
curl -fsSL https://happier.dev/install | bash
Windows:
iwr https://happier.dev/install.ps1 -useb | iex
If you specifically want the npm package instead: npm install -g @happier-dev/cli (CLI docs).
One command installs the CLI and the daemon on the remote host (release-signature verified) and registers it as one of your machines:
happier machine setup --ssh user@host
To sign the remote machine in without a browser on its side, run this from a machine where you are already signed in:
happier auth pair-remote --ssh user@host
Headless alternative on the remote host itself: happier auth login --no-open --method web prints an authorization URL you approve from any browser. Machines and the daemon
You sign in from the app, or on first run.
Sign in with the same account and your sessions, machines and settings are already there.
In the app → Press New session, pick the machine, the folder and the agent. No terminal needed.
Or in the terminal, from any project folder:
happier # Claude Code
happier codex # Codex
happier opencode # OpenCode
Either way, the session shows up everywhere at once: keep typing in the terminal, follow along and approve from your phone, review in the browser. happier --help lists the other agents and commands.
Parallel sessions, on every machine you own. Start as many sessions as you like and pick the machine, folder, agent and model for each one. Add a new machine over SSH from the app or the CLI. Starting a session · Machines and the daemon
Git worktrees, when you want them. Start each session in its own Git worktree: a real checkout, its own branch, the same repository. Happier creates it from any local or remote branch, suggests a name, and offers to reuse an existing one instead of duplicating it. Or start in the folder you are already in; it is a choice per session, not a mode you switch on: all your sessions, none of them, or just this one. New session options
Prefer the terminal? Keep it. Run Claude Code, Codex or OpenCode in their own terminal UIs: Happier mirrors those sessions to every device, so you can follow along, send messages and approve from anywhere, then switch between the terminal and the app whenever you like. Claude unified terminal
Your existing sessions? Already there. Open any Claude Code, Codex or OpenCode session already running on your machine: live, from any device, nothing to migrate and nothing to learn. Continuing a session
Subagents across agents. Any session can launch review, plan or delegate runs on another agent and read the results: Claude handing work to Codex subagents, Codex to Claude, or any other pairing. Subagents
Switch agents mid-session. Change the engine and the same session keeps going. A returning agent resumes its own thread and receives only what it missed. Continue with another agent
Hand a session to another machine. Move a live Claude Code or OpenCode session to your desktop, a VPS or a dev box, and bring the working tree along if you want it. Session handoff
Queue it, steer it. Queue messages while the agent works, reorder or edit them before they run, and steer a running turn without interrupting it. Steering · Pending queue
Review diffs, line by line. Browse your agent's changes, mark the exact lines you want addressed, and send the notes straight back: same session, or a new one. Review comments
Git from any device. Stage, commit, push, branch and open pull requests without leaving the app. Git
Files, editor, terminal. Open any file in a real editor, and drop into a live terminal on the connected machine when you need a shell. Files and editor · Embedded terminal
An inbox for what needs you. Permission requests, agent questions and unread sessions gather in one attention center across all sessions and machines, and push notifications open the exact session that asked. [Inbox and approvals](https://docs.happier.dev
