Best alternatives to Checkmate in 2026
Paying a monthly fee to a third-party service just to be told when your own server goes down is a strange trade for anyone comfortable running a bit of infrastructure themselves. Checkmate exists for that person: it's the monitoring dashboard and alerting layer, running on hardware you control, instead of a subscription to someone else's cloud. Checkmate is an open-source, self-hosted server and uptime monitoring tool built on Node.js and MongoDB, with a React and Material-UI dashboard for real-time visualization of uptime, response times, and incidents. It supports HTTP, Docker, ping, port, SSL, and game-server monitoring, plus infrastructure metrics like CPU, memory, and disk via a lightweight agent, and it can generate customizable, themed public status pages. Notifications go out through email, webhooks, Discord, Slack, PagerDuty, Telegram, and more, and the interface is available in 15+ languages. It's fully free under the AGPL-3.0 license, with no paid or hosted tier.
