Overview
Checkmate is a self-hosted monitoring tool that tracks whether your servers and websites are up and performing well, with real-time alerts, reports and visualizations of availability, downtime and response time.
What it does well
Checkmate monitors uptime, response times and incidents. An optional agent called Capture reports CPU, RAM, disk and temperature from remote servers, and runs on Linux, Windows, Mac and Raspberry Pi. The team says one deployment monitors more than 1,600 servers in production, and you can add worker nodes to go beyond 5,000. It runs with Docker Compose.
Why it’s in the collection
Checkmate covers uptime checks and server health in one self-hosted dashboard, so small teams don't need two paid services. It's AGPL-licensed.
