What Uptime Kuma is
Uptime Kuma is a free, self-hosted monitoring tool for checking services and servers. 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 go through Telegram, Discord, Gotify, Slack, Pushover, SMTP email, and more than 90 other notification services. Users can create multiple status pages and map them to specific domains. Other listed features include ping charts, certificate information, proxy support, multiple languages, and two-factor authentication. Installation instructions cover Docker Compose, Docker commands, and non-Docker setups. Non-Docker 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. The README says network file systems such as NFS are not supported and advises using a local directory or volume. The project license is MIT. The maintainer says general or technical support is not available by email and points users toward Google, GitHub Issues, or the project subreddit.
