"Cronitor has increased our Operations staff's efficiency and responsiveness immensely. Their spin on micro-monitoring represents a best-in-class solution to the age old problem of visibility."

Ethan Erchinger Director of Operations

"I was finding too many cases where our cron jobs would silently fail - we sometimes would not find out for days that a job was broken. Cronitor gives our team the confidence and peace of mind that if a job is not running, we'll know fast."

Gary Malouf VP of Technology

"Before we used Cronitor, we had an important data backup job fail silently for over a month. We use Cronitor so that will never happen again!"
