Why we included this project

Anyone who pays for more than one AI coding service has probably been cut off mid-task by a quota they forgot to check. onWatch is a small background daemon that tracks usage across Anthropic, Codex, GitHub Copilot, and other providers, so you can see how much budget is left and when the reset window opens before you get throttled. Everything is stored locally in SQLite and shown in a Material Design dashboard, with alerts and burn-rate views that make it easy to switch to a provider that still has headroom. It uses little memory and sends no telemetry, which matters if you want cost visibility without shipping your usage data anywhere. If you juggle several AI subscriptions, this gives you one place to watch the quotas.
