Desktop widget that tracks token usage and costs across 43+ AI coding tools, including Hermes Agent

In short

Token Monitor is a desktop widget that shows live token usage, costs and tool limits across 43+ AI coding tools. For Hermes Agent users, it reads token usage from the local ~/.hermes/state.db file.

What Token Monitor does

Token Monitor is a local-first desktop widget for macOS, Linux and Windows that gathers token usage from the data files AI coding tools leave on disk. It shows live usage and account limits in one dashboard, with historical trends and breakdowns by tool, device, model, session or project. Multi-device sync lets several machines feed the same view.

The README tables each supported tool with its data path and the kinds of data tracked. For Hermes Agent the data path is ~/.hermes/state.db, and the table lists token usage only, with no account-limit checks or session details. The same table covers Claude Code, Codex, OpenCode, OpenClaw, Cursor, Antigravity, GitHub Copilot, Cline and dozens more. The README is also available in Simplified Chinese, Traditional Chinese, Korean, Japanese and Portuguese.
