What Kuvasz Uptime is
Kuvasz Uptime is a free, open-source, self-hosted service for uptime and SSL monitoring. HTTP checks can use adjustable intervals, headers, keyword matching, expected status codes, and response-time checks. It also monitors SSL certificates, push checks, ICMP ping, TCP ports, and DNS. Users can create public or private brandable status pages, and schedule maintenance windows manually, as recurring cron jobs, or as one-off events to pause affected checks. Notifications can go to email, Slack, Discord, Telegram, Microsoft Teams, Apprise, Pushover, PagerDuty, or custom webhooks, with channels configurable per monitor. Monitors can be managed through the Web UI, REST API, or YAML configuration. A built-in MCP server exposes monitoring data and management operations to AI assistants and compatible clients. Kuvasz can export metrics to Prometheus or OTLP-compatible tools and has an official Home Assistant integration. It is distributed as a Docker image and can be deployed using Docker Compose or an official Helm chart. PostgreSQL is required, with PostgreSQL 14 listed as the minimum tested version. The AGPL-3.0 software is listed as free. Authentication can be configured or disabled, but disabling it may leave an exposed instance accessible to anyone.
