What is it?

Kuvasz is a self-hosted service for monitoring the uptime of websites and services and the validity of their SSL certificates. It covers HTTP(S), ICMP ping, TCP ports, DNS records, heartbeat (push) checks for cron jobs and backups, and Docker container health, and it can route checks through HTTP or SOCKS5 proxies.

Alerts can be sent per monitor to email, Discord, Slack, Telegram, Microsoft Teams, Apprise, Pushover, PagerDuty, or custom webhooks. Public or private status pages and maintenance windows let teams communicate planned downtime without triggering false alerts.

For automation, Kuvasz provides a REST API, YAML-based configuration, Prometheus and OpenTelemetry exporters, and an MCP server for querying and managing monitors from AI assistants. It is built with Kotlin and Micronaut.
