Our editorial assessment — not vendor-stated facts.
Free and open source; your only cost is the server you run it on — a $5/mo VPS is plenty. No per-monitor or seat fees. Because it is self-hosted, there is no vendor pricing to normalize.
Developers and homelabbers who want free, private uptime monitoring and are comfortable self-hosting it — it pairs naturally with a cheap VPS.
