Uptime Kuma Review

uptime.kuma.pet →

Uptime Kuma is a self-hosted, open-source monitoring tool for tracking uptime of websites, APIs, and services with a clean dashboard and notification alerts.

Chat Frontends & Clients

Verdict

Uptime Kuma has become one of the most popular self-hosted alternatives to commercial uptime monitors like UptimeRobot, praised for its polished UI, broad notification integrations (Slack, Telegram, email, and dozens more), and zero ongoing cost. It supports HTTP, TCP, DNS, and ping monitoring with customizable status pages you can share publicly. The tradeoff is that Docker or Node.js self-hosting is required, so it is not suitable for users who want a managed, no-ops solution.
