Keeps Claude Code, Codex, Cursor, and OpenCode managed in a window optimized for multi-agent workflows.
Features
Tabs represent a working directory. Each tab has a name and a root directory. Switch between them with ⌘1–⌘9.
Panes are terminal sessions inside a tab. Creating an agent pane launches the selected tool (Claude Code, Codex, Cursor, or OpenCode) in an isolated git worktree. You can also open a plain shell in an existing pane. Panes auto-arrange in a grid (1×1 → 2×1 → 2×2 → 3×2 → 3×3) as you add more.
Status line — each pane can show a live, configurable status bar at the bottom with app-owned and tool-specific information such as the model, worktree name, cost, context usage, and more. Available items vary by tool, and custom fields are supported in Settings → Status Line.
CLI options — each supported tool has its own catalog of configurable CLI options in Settings → Harnesses. Enabled options appear as toggles and text fields in the New Pane sheet. Custom flags are also supported.
Session persistence — tabs and pane names are saved and restored on relaunch. Any pane whose worktree still exists on disk is restarted automatically.
Keyboard shortcuts:
- ⌘T — new tab
- ⌘P — new pane
- ⌘W — close active pane
- ⌘K — close active tab
- ⌘1–⌘9 — switch to tab by index
Observability / Debugging — unified logs (Console.app / log stream) and Instruments signposts are always on, no setup needed. Enable Settings → Debug → Enable Debug Mode for durable trace/invariant JSONL files and the Trace (⌘⇧D) and Invariant (⌘⇧I) dashboards.
