Alert only when it matters.
Confirm outages and recoveries before alerting, so one failed check does not become a false alarm.
Reliability without
the noise.
Warden is an open-source, self-hosted uptime monitor for websites, APIs and services. It confirms real failures, learns normal response time and explains what changed.
Every service has its own normal.
Learn each service's normal response time, then catch slowdowns a global threshold misses.
History should explain the present.
See recurring slowdowns, time-of-day failures and services that break together.

Ask your AI assistant what is down, why a check failed and what changed. Warden provides live context through a permission-scoped MCP connection.
