Alternative to Datadog
Uptime Kuma is a monitoring tool for websites and services. It supports HTTP, TCP, DNS, Docker containers, and more protocols, detecting downtime and sending instant notifications.
- Multiple monitor types including HTTP(S), TCP, DNS, Docker, Steam, and MQTT
- Beautiful dashboard with real-time uptime percentage, response time, and status display
- 90+ notification services including Slack, Discord, Telegram, email, and webhooks
- Public status pages auto-generated for external visibility
- Certificate monitoring for SSL expiration alerts before certificates expire
- Maintenance scheduling to prevent false alerts during planned downtime
Built with Node.js and Vue.js, Uptime Kuma launches with a single Docker command. It provides a popular self-hosted alternative to UptimeRobot and Datadog for independent uptime monitoring.
