Uptime Kuma is a free, self-hosted monitoring tool for tracking websites, services, and containers. It checks HTTP(S), TCP, keywords and JSON queries over HTTP(S), WebSocket, Ping, DNS records, Push, Steam game servers, and Docker containers; monitoring intervals can run every 20 seconds. Teams can create multiple status pages and map them to specific domains, though published pages cache results for five minutes and refresh on that interval. Notifications include Telegram, Discord, Gotify, Slack, Pushover, and SMTP email, among more than 90 listed services; Apprise adds further notification options. The software supports proxies and two-factor authentication, and exposes Prometheus-compatible metrics at /metrics with basic authentication or API-key authentication. Installation instructions cover Docker Compose, a Docker command, and non-Docker setup for major Linux distributions. It is available for Linux, Windows, web, API, and self-hosted use, and is released under the MIT License, which permits modification and distribution, including selling copies. The project also provides a temporary Frankfurt demo server whose data is deleted after 10 minutes.
