Happier

### The multi-device control room to orchestrate teams of 100+ coding agents
  From your phone, desktop and browser.

  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.
