View guide →Uptime Kuma — a fancy self-hosted monitoring tool: uptime checks for sites and services every 20 seconds, with a beautiful status page and 90+ alert channels
Uptime Kuma is an open-source self-hosted project by louislam (louislam/uptime-kuma on GitHub). It has 92,566 GitHub stars and 8,565 forks, is released under the MIT license, and was last updated on GitHub on 17 October 2026.
The README one-liner starts Uptime Kuma on port 3001 with its data in a named volume.
Open http://localhost:3001, set up the admin account, then add a monitor — a URL, port, keyword check or one of the other supported types.
Attach notification channels so outages reach you, and publish a status page if others depend on your services.
HTTP(s), TCP, ping, DNS, Docker containers, databases, game servers and more, at intervals down to 20 seconds.
Telegram, Discord, Slack, Signal, email, webhooks and dozens more — alerts go where you already are.
Share uptime, incidents and maintenance windows on a clean page you control.
Runs on a Raspberry Pi or the smallest VPS; your monitoring data never leaves your server.

Yes — MIT licensed and fully self-hosted; your only cost is the machine it runs on.
Websites and APIs (HTTP/HTTPS, including keyword and JSON checks), TCP ports, ping, DNS, Docker containers, several databases, Steam game servers and more.
Against Uptime Robot, Uptime Kuma gives you the same core job — checks, alerts, status pages — self-hosted and free, with shorter check intervals than the free SaaS tiers, at the cost of running it yourself.
docker run -d -p 3001:3001 -v uptime-kuma:/app/data louislam/uptime-kuma:2, then open http://localhost:3001.
