+ strengths

  • GPL-3.0-or-later open source app, free to use, with a native (non-Electron) macOS build
  • Panes and sidebar badges signal when an agent is waiting; sidebar shows git branch, ports and notification text
  • Full CLI and socket API covering workspaces, splits, input, screen reads and the browser
  • SSH workspaces and tmux attach; Cloud VMs for agents on paid plans

! weak points

  • macOS only; other platforms are waitlist
  • Cloud VMs and the iOS app are on paid plans ($40/mo yearly for Pro, up to $160/mo for Max)
  • iOS app is beta (TestFlight)
  • Not a worktree manager: no worktree feature seen in docs or changelog; server components are BUSL-1.1, not GPL

~/who it is for

best for
Mac users who want a Ghostty-based terminal that surfaces which agent needs attention, with scriptable browser and CLI.
look elsewhere if
Windows or Linux users, or people wanting automatic per-agent git worktree isolation.
