FAQ

How does regression detection work?
We collect rolling response time samples for each endpoint and compute a statistical baseline. When a new measurement deviates beyond a configurable Z-score threshold (default 3σ), an alert fires immediately.
What kinds of APIs can I monitor?
Any HTTP/HTTPS endpoint — REST, GraphQL, or plain health-check URLs. You can configure custom headers, auth tokens, and request bodies per endpoint.
Can I cancel anytime?
Yes. Cancel from your billing portal with one click. You keep access until the end of your billing period with no questions asked.
