Kuvasz Uptime is an open-source, self-hosted uptime and SSL monitoring service built for developers and cloud-native environments. It is positioned as a self-hosted alternative to UptimeRobot, but with a stronger focus on configuration as code, APIs, metrics export, and deployment control. The documentation clearly states that it is released under the Apache License 2.0, is free, and will remain free.
It supports HTTP/HTTPS monitoring with configurable check intervals, GET/HEAD methods, request headers, request bodies, redirects, expected status codes, response-time thresholds, keyword matching, and response-header matching. SSL monitoring checks certificates daily and sends notifications before they expire. Push/heartbeat monitoring is suitable for tasks that cannot be actively probed, such as cron jobs and backups; ICMP monitoring can check host reachability, average round-trip latency, and packet loss. Status pages can be public or private, support custom logo/favicon, custom titles and slugs, and display uptime, average response time, and incident counts for the past 30 days.
Kuvasz provides a Web UI, a full REST API, and OpenAPI documentation. API authentication is handled via X-API-KEY or Bearer Token. Monitors and status pages can be managed from the UI, via the API, or through YAML files, making it a good fit for GitOps/IaC workflows. For deployment, it is distributed as a single Docker image, depends only on PostgreSQL, and also offers an official Helm Chart. Its integration capabilities are strong: notifications support Email, Slack, Discord, Telegram, PagerDuty, and custom Webhooks; metrics can be exported to Prometheus or OTLP-compatible tools; and there is also an official Home Assistant integration.
Pricing is one of its biggest advantages: it is free and open source. The comparison table shows unlimited monitors, with monitoring intervals as low as 5 seconds. The downside is that it is not a hosted SaaS product, so users need to maintain the database, deployment, backups, and upgrades themselves. Location-specific monitoring is not available out of the box and requires deploying instances in multiple regions. TCP monitoring and maintenance windows are still planned, while DNS and domain-expiration monitoring are not yet supported.
It is well suited to developers, SREs, small teams, and organizations that have Docker/Kubernetes experience and value data ownership. It is less suitable for users who want zero-ops monitoring with global nodes available immediately as a paid service. The source text does not provide details on access from China. Since the project is self-hosted, production access mainly depends on where the user deploys it. External ecosystem services such as GitHub, Docker Hub, Slack, Telegram, and PagerDuty may have network or availability differences in mainland China. Alternatives include Uptime Kuma, UptimeRobot, Better Stack, Healthchecks.io, and Prometheus Blackbox Exporter.
