Token Tracker auto-collects token counts from AI coding tools (Claude Code, Codex, Cursor, Gemini CLI, Roo Code, Zed Agent, Goose, and others), aggregates the data locally without requiring cloud accounts or API keys, and presents real-time cost trends via a dashboard. It ships as a CLI for macOS/Linux/Windows, a native macOS menu bar app with 4 widgets, and a Windows system tray app.
