Agent Island

Agent Island helps developers track long-running Claude Code, Codex, Grok, Antigravity, and Cursor sessions without repeatedly returning to each terminal or editor. It reads local session evidence and shows whether work is running, stalled, finished, or waiting for human input. Your-turn alarms take you back to the relevant session. The free, MIT-licensed app supports the same five providers on macOS and Windows, keeps session monitoring and usage or cost estimates local, requires no Agent Island account, and sends no product telemetry.

It is built for developers running one or more coding agents who need a clear status view without granting a separate cloud service execution authority.
