Catch silent API
breaking changes
before your customers
do
We monitor the endpoints you register and compare each response against its known shape. A change is confirmed across multiple observations before it ever fires, so alerts stay low-noise — then you're paged on Slack, a webhook, or PagerDuty with exactly what changed.
This demo only reads public API specs — no credentials involved. In the real product, a lightweight open-source agent runs on your own infrastructure, so your API keys never leave it — we only ever see schema metadata, never the actual request or response data.
