What Uptime Kuma is

Uptime Kuma is a free, self-hosted monitoring tool for checking services, servers and other endpoints. It can monitor HTTP(S), TCP, HTTP(S) keywords and JSON queries, WebSocket, ping, DNS records, push endpoints, Steam game servers and Docker containers. The README lists monitoring intervals of 20 seconds. Notifications can be sent through Telegram, Discord, Gotify, Slack, Pushover, SMTP email, Apprise and more than 90 services. Users can create multiple status pages and assign them to specific domains. Other listed features include ping charts, certificate information, proxy support, multiple languages and two-factor authentication. Installation guidance covers Docker Compose, Docker commands and non-Docker setups. For non-Docker installations, supported requirements include major Linux distributions and 64-bit Windows 10 or Windows Server 2012 R2 or higher. FreeBSD, OpenBSD, NetBSD, Replit and Heroku are marked unsupported. Network file systems such as NFS are not supported; the project advises using a local directory or volume. Uptime Kuma is licensed under MIT. The maintainer says general or technical support is not available by email and points users toward Google, GitHub Issues or the project subreddit.
