Why it matters

For developers running several coding agents at once who lose track of which one needs input or what the last agent did.

Highlights

Floating cards surface approval requests and questions from agents, color-coded per project.
Parallel agents can each get their own git worktree and branch; a per-project WORKBENCH.md holds a shared task list.
Token tracking projects remaining usage; a project optimizer scores and fixes agent files.
An iPhone app (on the App Store) monitors and approves agents; remote development works over SSH.

Taken from the project's own README, docs or launch page. Claims about speed or accuracy are the maker's unless stated otherwise.

Try it if: You run multiple Claude Code, Codex or opencode sessions and want one place to monitor and approve them.

Worth knowing: macOS only. Deeper integrations (hooks) depend on the agent; the site says Antigravity CLI lacks them.
