Monitors
Every API and MCP server we keep an eye on, with the most recent diff for each.
See exactly what we're keeping an eye on — and add your own.
We follow OpenAPI specs, public changelogs, and MCP server schemas around the clock, so your team finds out about changes long before your customers do.

Every diff, kept
We snapshot on every check, so you can scroll back through an API's full story — not just the latest blip.
Bring your own
Drop in an OpenAPI 3.x / Swagger 2.x spec, or the URL of your own MCP server, and we'll start watching it on the same cadence.
One free account. Three monitors. Zero setup.
