Uptime Kuma
What it is
Uptime Kuma is a free, self-hosted monitoring tool for checking services, servers, and containers. It supports HTTP(S), TCP, keyword and JSON-query checks, 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 assign them to specific domains. Those pages cache results and refresh every five minutes. Notifications include Telegram, Discord, Gotify, Slack, Pushover, and SMTP email, among more than 90 listed services; Apprise can provide additional notification options. Prometheus-compatible metrics are available at /metrics with basic authentication or an API key. The project lists proxy support and two-factor authentication. Installation instructions cover Docker Compose, a Docker command, and non-Docker setup on major Linux distributions. Uptime Kuma is released under the MIT License, which permits use, modification, and distribution, including selling copies. A temporary Frankfurt demo server is available, with its data deleted after 10 minutes.
