onWatch is a free, open-source CLI tool that tracks Synthetic, Z.ai, Anthropic (Claude Code), Codex, GitHub Copilot, and Antigravity API quota usage in real time. It runs as a lightweight background agent (<50 MB RAM with all six providers polling in parallel), stores historical data in SQLite, and serves a Material Design 3 web dashboard with dark/light mode.
onWatch fills the gap between "current usage snapshot" and the historical, per-cycle, cross-session intelligence that developers actually need. It works with any tool that uses Synthetic, Z.ai, Anthropic, Codex, GitHub Copilot, or Antigravity API keys, including Cline, Roo Code, Kilo Code, Claude Code, Codex CLI, Cursor, GitHub Copilot, Antigravity, and others.
Zero telemetry. Single binary. All data stays on your machine.
If onWatch helps you track your AI spending, consider giving it a star — it helps others discover the project.
Beta: onWatch is currently in active development. Features and APIs may change as we refine the product.
