Agent Island is an open-source status companion for Claude Code and Codex. It shows whether local coding-agent sessions are running, waiting, or need input, and can notify you when it is your turn. It runs on macOS and Windows and reads session data locally; session data is not uploaded to Agent Island. The MIT-licensed source and releases are available on GitHub.

On macOS, Agent Island also includes local usage views and report cards with API-value estimates. Those figures are estimates, not billing records. Windows feature coverage is limited to the capabilities documented for the current stable release.

Install on macOS with Homebrew or the signed DMG. On Windows, download the current x64 ZIP release.
