onWatch

**Free, open-source AI API quota monitoring for developers.**

Track usage across [Synthetic](https://synthetic.new), [Z.ai](https://z.ai), [Anthropic](https://anthropic.com), [Codex](https://openai.com/codex), [GitHub Copilot](https://github.com/features/copilot), [MiniMax](https://platform.minimax.io), [Gemini CLI](docs/GEMINI_SETUP.md), and Antigravity in one place. See history, get alerts, and open a local web dashboard before you hit throttling or run over budget.

onWatch fills the gap between "current usage snapshot" and the historical, per-cycle, cross-session view that developers actually need. It runs as a lightweight background agent (<50 MB RAM with all eight providers polling in parallel), stores historical data in SQLite, and serves a Material Design 3 web dashboard with dark/light mode.

It works with any tool that uses Synthetic, Z.ai, Anthropic, Codex, GitHub Copilot, MiniMax, Gemini CLI, or Antigravity API keys, including **Cline**, **Roo Code**, **Kilo Code**, **Claude Code**, **Codex CLI**, **Cursor**, **GitHub Copilot**, **MiniMax Coding Plan**, **Antigravity**, and others.

**Zero telemetry. Single binary. All data stays on your machine.**

**Beta:** onWatch is currently in active development. Features and APIs may change as we refine the product.
