Side by side
A health dashboard and status page that checks endpoints against conditions defined in YAML, with alerting and incident announcements.
A self-hosted monitoring tool that checks HTTP, TCP, ping, DNS, Docker and more, sends alerts through 90+ notification services and publishes status pages.
Configuration lives in files, with no UI for adding monitors, which suits engineers more than operators.
Single-instance design, so it does not monitor from multiple locations or scale to very large numbers of checks.
