About Cronitor
What is Cronitor?
Cronitor is a monitoring platform built for developers. It helps you track cron jobs, background agents, websites, APIs, and any system that can send a heartbeat. The tool detects failures, slowdowns, and silent outages in real time, sending alerts via email, Slack, PagerDuty, and more.
What problem does it solve?
Silent failures are a nightmare for engineering teams. A cron job can break and go unnoticed for days, causing data loss or downstream chaos. Cronitor eliminates that risk with automated checks, instant alerts, and detailed metrics. It also monitors uptime, SSL certificates, and website performance from 12+ global locations.
Who is it for?
Cronitor is best for developers, DevOps, and operations teams who need reliable, code-friendly monitoring for backend jobs and endpoints. It is NOT for non-technical users seeking all-in-one no-code dashboards. Real use cases include: alerting on failed data exports, tracking scheduled scripts, monitoring API performance, and building public status pages to communicate uptime during incidents.
