README
Syrtis
AI token usage & quota monitor for the macOS menu bar — native Swift, Liquid Glass.
**Syrtis** is a free, open-source macOS menu-bar app that reads the session logs your AI coding tools already write to disk and displays your tokens, costs, and subscription quotas. It supports 25+ tools—including Claude Code, Codex, Cursor, OpenCode, Gemini CLI, Copilot, Kiro, and Antigravity—completely on-device, with no Dock icon, no telemetry, no user account, and no cloud sync.
Until version 2.0, the app was called TokenBar on macOS; upgrading preserves your settings, history, and login item unchanged. A companion Windows tray version, also named [Syrtis](https://github.com/Nanako0129/Syrtis-Windows), is built on the same Rust core.
The menu-bar title displays today's token count, total cost, live tokens per minute, or remaining subscription quota—shown as signal bars, a progress ring, or a popsicle that melts as the window drains
