Uptime Kuma

What is Uptime Kuma?

Uptime Kuma is a self-hosted, open-source monitoring tool for tracking whether websites, servers and services are up. It is licensed under MIT and runs on your own infrastructure.

Key features of Uptime Kuma

• Monitor types: HTTP(s), TCP, ping, HTTP keyword and JSON query, WebSocket, DNS record, push, Steam game server and Docker containers.
• Fast checks: intervals as short as 20 seconds.
• Status pages: multiple status pages that can be mapped to specific domains.
• Notifications: 90+ services, including Telegram, Discord, Gotify, Slack, Pushover and email.
• Other tools: ping charts, certificate info, proxy support and 2FA.

How Uptime Kuma works

You install it with Docker Compose, a Docker command, or directly with Node.js 20.4 or later, open the web UI on port 3001 and add monitors. Checks run from your server and alerts go to your notification channels.

Who uses Uptime Kuma?

Developers, homelab users and small operations teams who want a free, self-managed monitor use Uptime Kuma. It supports major Linux distributions and Windows 10 or Server 2012 R2 and later.

Uptime Kuma pricing

Uptime Kuma is free and open source under the MIT license, so there is no subscription. You pay only for the server you run it on.

Uptime Kuma integrations

Uptime Kuma includes built-in notification integrations for Telegram, Discord, Gotify, Slack, Pushover and email over SMTP, and the project cites more than 90 notification services in total.

Uptime Kuma alternatives

Datadog is a commercial observability suite with a hosted model rather than self-hosting. New Relic is a hosted full-stack monitoring service. Better Stack is a hosted uptime and logging service with a free tier. Uptime Kuma suits teams who want to run it themselves.
