These two do different jobs. Vibe Island is a control panel for running agents: it lives in the notch, shows each session, and lets you answer permission prompts and jump to the right terminal. Cost Doctor is about cost and failures: which Claude Code or Codex session uses your tokens, why, when you will hit your limit, and a red alert when a check fails.

What the other tool does and costs is taken from its own page, as checked in November 2026. Tools change; check their page for the current details.

See it on your own sessions
Cost Doctor is a Mac menu bar app that reads the logs Claude Code and Codex already write. It names the session that is using your tokens, says why, and turns your screen red when a check fails while an agent sits waiting. Nothing leaves your Mac.
