About Cronitor

Cronitor is a monitoring service built for developers. It tracks scheduled jobs, background workers, websites and APIs, and sends alerts when something fails, runs late or never starts.

What it does

Cronitor watches jobs by their schedule and by heartbeat pings sent from your code. It records the status, metrics and output of each run so you can see what happened. Uptime and performance checks run from many regions, and alerts go to channels such as Slack, PagerDuty and email.

Key features

  • Cron job monitoring with schedule-based alerts
  • Heartbeat monitors for workers and background tasks
  • Uptime and performance checks from 12 or more locations
  • Run history with status and output
  • Alerts to Slack, PagerDuty and email

Who it's for

Developers and operations engineers who run cron jobs, queues and scheduled tasks and want to know about failures before users do. It also suits teams that want one tool for both job monitoring and endpoint checks.

Pricing and good to know

You can start for free, and the team offers a call with a developer for larger needs. The service includes SDKs and an API for integration, so monitors can be created from your own code.
