Kuvasz Uptime vs SiteUptime

Kuvasz Uptime is free, open-source, self-hosted monitoring software for uptime, SSL certificates, keywords, servers, and infrastructure checks. HTTP monitors support adjustable intervals, headers, keyword matching, expected status codes, and response-time checks. Other monitor types include SSL certificate, push, ICMP ping, TCP port, and DNS monitoring. You can create public or private brandable status pages and schedule maintenance windows manually, by recurring cron schedule, or as one-off events to pause affected checks. Notifications can use email, Slack, Discord, Telegram, Microsoft Teams, Apprise, Pushover, PagerDuty, or custom webhooks, configured per monitor. Metrics export to Prometheus or OTLP-compatible tools, and an official Home Assistant integration is available. Monitors can be managed through the Web UI, REST API, or YAML. Deployment uses Docker, Docker Compose, or an official Helm chart and requires PostgreSQL; PostgreSQL 14 is the minimum tested version listed. The Free plan costs nothing, with the monitor limit not stated.
