Uptime Kuma

Self-hosted monitoring tool that checks websites and services and sends alerts and status pages.

Our verdict

Good for homelabbers and small teams who want simple uptime checks and status pages on their own server. Skip it if you want a hosted service.

What it does well

Monitors HTTP(s), TCP, ping, DNS, push, Docker containers and more
Notifications to 90+ services and multiple public status pages

Where it falls short

Not supported on FreeBSD, OpenBSD, NetBSD, Replit or Heroku
NFS and similar network file systems are not supported for data storage

The Uptime Kuma website — The official Uptime Kuma website, 17 October 2026.

Uptime Kuma is a self-hosted monitoring tool. According to its repository it can monitor uptime for HTTP(s), TCP, keyword, JSON query, WebSocket, ping, DNS record, push, Steam game server and Docker container monitors, with checks at 20-second intervals.

It sends notifications through Telegram, Discord, Gotify, Slack, Pushover, email (SMTP) and more than 90 other services, and offers multiple status pages that can be mapped to specific domains. It also has certificate info, proxy support and 2FA.

Uptime Kuma has no price or plans: it is MIT licensed and you run it yourself. It installs with Docker Compose or a single docker command, or without Docker using Node.js 20.4 or later, Git and (optionally) PM2 on Linux or Windows. The web interface runs on port 3001.
