⚡️ Quick start guide

If you want to get started quickly, please refer to the Deployment guide in the documentation.

✨ Features

  • HTTP(S) monitoring: Monitor the availability and performance of your websites and services by sending HTTP(S) requests.
  • SSL certification monitoring: Automatically check the SSL certificates of your monitored services to ensure they are valid and not expired.
  • Heartbeat (push) monitoring: Monitor your cron jobs, backups, and other scheduled tasks in a push-based manner, getting alerted when an expected heartbeat doesn't arrive in time.
  • Ping (ICMP) monitoring: Check the reachability and latency of any host by sending ICMP echo requests (pings) to it.
  • TCP port monitoring: Check whether any TCP service — databases, SMTP, SSH, message brokers, and more — accepts connections, and track connect latency.
  • Notifications on a per-monitor basis: Configure different notification channels for each monitor, allowing you to tailor alerts to your specific needs.
  • Status pages: Create public or private status pages to keep your users or your own team informed about the status of your services.
  • Sleek UI: Kuvasz has a modern, responsive, and user-friendly interface that makes it easy to manage your monitors.
  • Full-fledged REST API: Manage your monitors, check their status, and more through a powerful API.
  • Metrics exporters: Export your metrics to OpenTelemetry and Prometheus for better observability and integration with your existing monitoring stack.
  • Home Assistant integration: With the official Home Assistant integration you can easily integrate your monitors into your smart home setup, create custom dashboards, and automate actions based on the status of your services.
  • MCP server: The MCP server allows you to leverage the capabilities of Kuvasz via AI assistants, enabling you to query monitor status, view incidents, and create or toggle monitors through natural language.
  • Maintenance windows: Schedule planned downtime so Kuvasz pauses the affected checks and suppresses false alerts — manually, on a recurring cron schedule, or as a one-off event.
  • More to come: Take a look at our Roadmap
