What is Uptime Kuma?
Uptime Kuma is a free, open-source (MIT-licensed) self-hosted monitoring tool created by Louis Lam.

Key capabilities
- Multi-protocol monitors: HTTP(s), TCP, ping, DNS, Docker containers and more.
- Public status pages: Shareable pages built from your monitor groups.
- Notifications: 90+ integrations including Telegram, Discord, Slack and email.
Self-hosted uptime and status-page monitoring is the primary use case.
Shortlist Uptime Kuma when you want a free, self-hosted alternative to Uptime Robot or Pingdom and can run and maintain your own instance (Docker, a small VPS, or even a Raspberry Pi).
Since there is no vendor SLA, confirm who owns your instance's uptime, backups and alert delivery before relying on it for anything customer-facing.
