Cronitor

Cronitor monitors scheduled jobs, background processes, websites, and APIs. Its heartbeat monitoring receives periodic HTTP signals from your systems and alerts your team when expected activity stops or reported values breach configured thresholds. Teams can track workers, scripts, data pipelines, and devices without exposing an inbound endpoint. Cron job monitoring also records execution status, duration, metrics, and output to help investigate missing or failed runs.

• Missing-heartbeat and explicit-failure alerts
• Custom metric charts and threshold assertions
• Configurable grace periods and failure tolerances
• Dashboard, API, SDK, and configuration-as-code setup
• Cron job execution status, duration, metrics, and captured output
• Website/API monitoring and status pages

What does Cronitor heartbeat monitoring detect?

It detects missing expected signals and explicit failures. Custom metric assertions can also trigger alerts when a process still reports activity but its results fall outside configured limits.

Do monitored processes need a public endpoint?

No. They send outbound HTTP/HTTPS requests to Cronitor, so an inbound public endpoint is unnecessary. Outbound connectivity is still required.

Is Cronitor free?

The Hacker plan includes five monitors and one dashboard user. Business costs $2 per monitor/month plus $5 per user/month, with optional extras charged separately. Check the vendor pricing page for current terms.
