Checkmate

An open source uptime and infrastructure monitoring application

This repository contains both the frontend and the backend of Checkmate, an open-source, self-hosted monitoring tool for tracking server hardware, uptime, response times, and incidents in real-time with beautiful visualizations. Checkmate 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 insights about your servers’ CPU, RAM, disk, and temperature status.

Checkmate has been stress-tested with 1000+ active monitors without any particular issues or performance bottlenecks.

📦 Demo

You can see the latest build of Checkmate in action. The username is uptimedemo@demo.com and the password is Demouser1! (just a note that we update the demo server from time to time, so if it doesn’t work for you, please ping us on the Discussions channel).

🔗 User’s guide

Usage instructions can be found here. It’s still WIP and some of the information there might be outdated as we continuously add features weekly. Rest assured, we are doing our best! :)

🛠️ Installation

See installation instructions in Checkmate documentation portal.

Alternatively, you can also use Coolify, Elestio, K8s or Pikapods to quickly spin off a Checkmate instance. If you would like to monitor your server infrastructure, you’ll need Capture agent. Capture repository also contains the installation instructions.

🚀 Performance

Thanks to extensive optimizations, Checkmate operates with an exceptionally small memory footprint, requiring minimal memory and CPU resources. Here’s the memory usage of a Node.js instance running on a server that monitors 323 servers every minute:

You can see the memory footprint of MongoDB and Redis on the same server (398Mb and 15Mb) for the same amount of servers:
