Uptime Kuma

Uptime Kuma is an easy-to-use self-hosted uptime monitoring service for servers, websites, and network endpoints. It provides a modern web UI to configure monitors, receive alerts, and publish status pages.

Key Features

• Multiple monitor types including HTTP(S), TCP, ping, DNS record, WebSocket, keyword checks, JSON query checks, and push-based monitoring
• Fast single-page web interface with real-time updates
• Multi-channel alerting with many notification integrations (including email/SMTP and common chat and push services)
• Public status pages with support for multiple pages and custom domain mapping
• Charts and visibility features such as ping graphs and certificate/TLS information
• Proxy support for checks and optional two-factor authentication

Use Cases

• Track uptime and latency for websites, APIs, and internal services
• Monitor homelab infrastructure and receive instant downtime notifications
• Publish a simple public status page for customers or teammates

Limitations and Considerations

• Network file systems such as NFS are not supported for the data directory and can cause instability

Uptime Kuma is a practical alternative to hosted uptime monitoring services when you want control over data and integrations. It is well-suited for individuals and teams that need straightforward monitoring, alerting, and shareable status pages.
