What Uptime Kuma is
Uptime Kuma is a free, self-hosted monitoring tool for checking websites, services, servers, and containers. It can monitor HTTP(S), TCP, HTTP(S) keywords and JSON queries, WebSocket, Ping, DNS records, Push, Steam game servers, and Docker containers, with intervals as short as 20 seconds. Users can create multiple status pages and map them to specific domains. Published status pages cache results and refresh every five minutes. Native notifications include Telegram, Discord, Gotify, Slack, Pushover, and SMTP email; more than 90 notification services are listed, and Apprise can add further options. The software supports proxy use and two-factor authentication. Prometheus-compatible metrics are available at the /metrics endpoint, protected by basic authentication or an API key. Installation choices include Docker Compose, a Docker command, and non-Docker setup for major Linux distributions. Released under the MIT License, Uptime Kuma permits use, modification, and distribution, including selling copies. Its project also provides a temporary Frankfurt demo server whose data is deleted after 10 minutes.
