Know when your business silently breaks

Heron detects when critical events like payments, signups, or emails stop — even when your system looks healthy.

The bugs you don't see are the most dangerous

Traditional monitoring catches crashes and errors. But what about when things simply stop happening?

No errors, but payments stop

Your monitoring shows green, but revenue silently stops flowing.

Email jobs silently fail

Critical notifications never reach your customers, and you don't know until they complain.

Background workers stop running

Scheduled tasks quietly die without triggering any alerts in your system.
