What Is Healthchecks.io?


Healthchecks.io monitors cron jobs by expecting regular pings. If a ping doesn't arrive on time, something is wrong — and you get alerted.


How It Works


1. Create a check with an expected schedule

2. Add a ping to your cron job: `curl https://hc.example.com/ping/uuid`

3. If the ping doesn't arrive on time, Healthchecks alerts you
