Self-hosted uptime monitoring with a fancy reactive interface
Easy-to-use self-hosted monitoring tool for tracking uptime across HTTP, TCP, ping, DNS, Docker containers, and more with 90+ notification integrations.
Uptime Kuma is a self-hosted monitoring solution designed for teams and individuals who need reliable uptime tracking without depending on third-party services. Built with Vue 3 and powered by WebSocket communication, it delivers a responsive, real-time interface for monitoring infrastructure health.
Monitor diverse endpoints including HTTP(s), TCP ports, ping targets, DNS records, Docker containers, and Steam game servers. Track keyword presence, query JSON responses, or receive push-based health checks. The platform supports 20-second check intervals and displays certificate information, ping charts, and historical data through an intuitive dashboard.
Notifications reach your team through 90+ services including Telegram, Discord, Slack, email, and Pushover. Create multiple status pages mapped to custom domains, enable two-factor authentication, and configure proxy support for complex network topologies.
Deploy via Docker with a single command or install directly on major Linux distributions, Windows 10+, and Windows Server 2012 R2+. The application requires Node.js 18/20.4+ and runs on port 3001 by default. PM2 process management is recommended for non-Docker deployments to ensure background operation and automatic restarts.
When teams consider Uptime Kuma, these hosted platforms usually appear on the same shortlist.
