About

Uptime Kuma is a free, self-hosted monitoring tool for services, servers, and containers, available for Linux, Windows, web, API, and self-hosted use. It checks HTTP(S), TCP, HTTP(S) keywords and JSON queries, WebSocket, Ping, DNS records, Push, Steam game servers, and Docker containers, with monitoring intervals as short as 20 seconds. Users can publish multiple status pages and map them to specific domains; those pages cache results and refresh every five minutes. Native notifications include Telegram, Discord, Gotify, Slack, Pushover, and SMTP email, among more than 90 listed services. Apprise provides additional notification options. The project supports proxy use and two-factor authentication, and exposes Prometheus-compatible metrics at /metrics with basic or API-key authentication. Installation instructions cover Docker Compose, a Docker command, and non-Docker setups for major Linux distributions. The MIT License permits use, modification, and distribution, including selling copies. A temporary Frankfurt demo server is available, with its data deleted after 10 minutes.

Who it is for
