What does Cronitor do?
Cronitor is a monitoring platform built for developers. It tracks the health and performance of critical backend systems. You can use it to monitor scheduled cron jobs, check the uptime of websites and APIs, and keep a pulse on any part of your infrastructure using simple heartbeat events. The goal is to catch failures quickly, before they become bigger problems, and to provide clear visibility into system reliability.
The tool works by integrating with your applications via its SDKs or a straightforward API. For cron jobs, it captures status, metrics, and logs. For websites, it runs checks from over a dozen global locations. You can set up custom assertions for complex monitoring logic and receive alerts through a wide range of integrations like Slack, email, and PagerDuty. A key feature is its integrated status pages, which automatically reflect your system's health for your customers or internal teams.
This service is most useful for development and operations teams who need to ensure their automated tasks run correctly and their services stay online. Real-world use includes monitoring nightly data export jobs, verifying that customer-facing APIs are responding, and tracking key business metrics like new user sign-ups through heartbeat events. It helps teams move from reactive firefighting to proactive system management.
