Best for
Developers running several coding agents in parallel who want to see status and handle approvals at a glance, including from their phone when away from the desk.
Not ideal for
Users who want a pure productivity tool without a playful mascot, or those needing App Store distribution today (Mac and iPhone App Store builds are still pending).
A fast-moving, genuinely cross-platform agent monitor that makes approvals and session status ambient; its feature scope is expanding beyond agents, but agent supervision remains the core reason to install it.
Coucou 0.4.0 (October 15, 2026) turned the Mac build into a full Dock app with offline Parakeet dictation and call notetaking; Windows and Linux builds plus an Android app (October 11–13, 2026) followed the late-September first release.
