An open source uptime and infrastructure monitoring application
 This repository contains the **frontend** 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](https://github.com/bluewave-labs/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. Checkmate has ben stress tested with 1000+ active monitors without any particular issues or performance bottlenecks. We **love** what we are building here, and we contibuously learn a few things about Reactjs, Nodejs, MongoDB and Docker while building Checkmate. For backend files, please check [Checkmate backend](https://github.com/bluewave-labs/checkmate-backend) repository. ## 📦 Demo See [Checkmate](https://checkmate-demo.bluewavelabs.ca/) 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 Discussions channel). ## 🔗 User's guide Usage instructions can be found [here](https://docs.checkmate.so/). It's still WIP and some of the information there might be outdated as we continuously add features weekly.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](https://docs.checkmate.so/quickstart). Alternatively, you can also use [Coolify](https://coolify.io/) or [Elestio](https://elest.io/open-source/checkmate) for a one click Docker deployment. If you would like to monitor your server infrastructure, you'll need [Capture agent](https://github.com/bluewave-labs/capture). 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:  ## 💚 Questions & ideas If you have any questions, suggestions or comments, please use our [Discord channel](https://discord.gg/NAb6H3UTjK).
