Uptime Kuma

Open-source, self-hosted monitoring tool featuring a reactive UI, extensive notification integrations, and Docker container tracking.

About Uptime Kuma

Uptime Kuma is a wildly popular, open-source, and self-hosted monitoring solution designed as an alternative to proprietary SaaS platforms. Built with a modern, reactive Vue.js interface, it offers administrators a fast, clean, and highly customizable environment to track the health of their entire infrastructure without relying on external cloud providers.

The platform is favored by homelab enthusiasts and privacy-conscious enterprises alike. Because it is self-hosted via Docker or Node.js, data remains entirely on-premise. Despite being open-source, it boasts an incredible breadth of monitoring types—ranging from standard HTTP to complex game server polling—and supports a massive ecosystem of third-party notification services.
