What Checkmate does

Checkmate checks at fixed intervals whether websites, servers and services respond, keeps response times and outages as history and notifies you when something is down.

The monitored services can be assembled into a public status page.

  • HTTP, ping and port checks
  • Response times and outages over time
  • Notifications by email and webhook
  • Public status page

Good to know before the first start. Checkmate keeps its state in a MongoDB inside the same pod. Backups include it as a file copy; for a perfectly clean snapshot, pause the pod briefly first.

Checkmate instead of UptimeRobot

Also instead of Pingdom, Statuspage, StatusCake, Better Stack.
