Checkmate

An open source server monitoring application

Checkmate is an open source uptime manager, server & Docker monitoring tool used to track the operational status and performance of servers and websites. It regularly checks whether a server/website is accessible and performs optimally, providing real-time alerts and reports on the monitored services' availability, downtime, and response time.

Checkmate also has an agent, called Capture, to retrieve data from remote servers. While Capture is not required to run Checkmate, it provides additional insigths about your servers' CPU, RAM, disk and temperature status.

We've run stress tests with 1000+ active monitors without any particular issues or performance bottlenecks.

We love what we are building here, and learn a few things about Reactjs, Nodejs, MongoDB and Docker while building Checkmate. If you would like to support us, please consider giving it a ⭐, think about contributing or providing feedback. Please note that we do not operate a monetary donation program, make money by deploying servers, or run a SaaS business.
