Healthchecks

Healthchecks monitors expected pings and alerts you when one arrives late. It listens for pings, checks whether each one arrives on time, and sends an alert when an expected ping does not appear as expected. Its purpose is deliberately narrow: it provides a straightforward way to know when a ping is late, rather than requiring you to monitor those pings yourself. It is for people or teams that need to monitor expected pings and receive alerts about delayed ones. For this specific automation task, Healthchecks can replace a paid product such as Zapier, and its source code is available under the BSD-3-Clause license. An important limitation is that Healthchecks is centered on two core functions: listening for pings and notifying you when they are late. It should therefore be considered a focused replacement for ping monitoring and late-ping alerts, not a replacement for unrelated automation tasks.
