Uptime Kuma

Uptime Kuma is a self-hosted uptime monitoring tool for tracking availability and latency of websites, APIs, and network services. It provides a web dashboard to manage monitors, view history, and receive notifications when checks fail.

Key Features

• Multiple monitor types (HTTP(s), TCP port, Ping, DNS, keyword search, etc.) to fit common availability checks
• Configurable intervals, retries, timeouts, and status history for each monitor
• Alerting via many notification providers (e.g., email/SMTP, Telegram, Discord, Slack, Webhooks, and more)
• Public or private status pages with custom branding and incident-style visibility for selected monitors
• TLS/SSL certificate expiry monitoring for HTTPS endpoints
• Multi-user support with authentication and session management
• Docker-based deployment support and lightweight standalone operation

Use Cases

• Monitor public websites and APIs and alert on downtime or slow responses
• Track internal services (databases, NAS, homelab apps) via TCP/Ping and centralize alerts
• Publish a simple external status page for customers or internal stakeholders

Limitations and Considerations

• It is primarily an availability/health checker and does not replace full observability stacks (logs/traces/metrics)

Uptime Kuma is a practical choice for individuals and teams needing an easy-to-operate monitoring dashboard with broad notification support. It suits homelabs and small-to-medium deployments where quick setup and clear uptime history are priorities.
