Uptime Kuma
An open-source uptime tool checking HTTP, TCP, WebSocket, DNS, Ping, Docker, and Steam game servers with more than ninety notification integrations and multiple status pages.
Why use it
Use Uptime Kuma to monitor websites, patches, login, matchmaking, and community services cheaply, alert responders during incidents, and reduce duplicate questions through a public status page.
Where it fits
Use analytics, feedback, player support, and updates to fix issues and decide what to improve after launch.
What to check
The MIT tool is free, but its monitor needs reliable hosting, backups, and tested alerts, and one node can become a blind spot; it does not replace logs, traces, security monitoring, or multi-region probes.
