cState vs UptimeSignal
Both stand on status page software. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
cState is a free, open-source option for Markdown-based status pages and operational records. Teams needing monitoring automation should note that it is an optional addition rather than part of the static core.
Visit cStateChoose UptimeSignal if you want endpoint monitoring and unlimited public status pages, with alert channels included even on the free plan. Pro is the route to unlimited monitors, one-minute checks, custom domains, and lightweight event tracking.
