Know the moment your API drifts from its spec.
Your OpenAPI spec (or MCP server's tool schema) says one thing. Your live service does another. We tell you the moment they diverge -- without ever asking for your production credentials.
Self-hosted by default
The checker runs on your GitHub Actions, using your repo secrets. It computes the diff locally and posts only a pass/fail result here -- your credentials never leave your own infrastructure.
Hosted mode, opt-in
Prefer convenience? Give us a scoped, read-only key and we'll check on a schedule instead. Every hosted API is clearly labeled in the dashboard so you always know your exposure.
MCP schema drift, too
We treat an MCP server's tool schema the same as an OpenAPI contract -- a category almost nobody else is monitoring yet.
Alerts that explain themselves
A plain-English summary, the likely commit that caused it, and a noise filter so you stop getting paged for the same false positive twice.
