Frequently Asked Questions
Everything you need to know about cron job monitoring
What is cron job monitoring?
Cron job monitoring tracks whether your scheduled tasks (cron jobs, background workers, pipelines) actually run on time. CronSafe gives each job a unique ping URL — if the ping doesn't arrive within the expected window, you get alerted instantly via email or webhook.
How does CronSafe work?
Add a single curl command to the end of your cron job or script. Each time the job runs successfully, it pings your unique CronSafe URL. If CronSafe doesn't receive a ping within the expected interval (plus a configurable grace period), it triggers an alert.
Is CronSafe free?
Yes! The free plan includes up to 3 monitors, email alerts, and 24-hour ping history. No credit card required. Upgrade to Pro ($9/mo) for unlimited monitors, Slack/Discord integration, and 90-day history.
What happens if my cron job fails silently?
That's exactly what CronSafe prevents. Silent failures are the most dangerous — your job stops running but nobody notices until data is lost or users complain. CronSafe detects the missing ping and alerts you immediately.
Can I monitor Docker containers and Kubernetes jobs?
Absolutely. CronSafe works with any scheduled task — cron jobs, Docker containers, Kubernetes CronJobs, Celery tasks, Sidekiq workers, or any process that can make an HTTP request. Just add a curl to your health check.
How is CronSafe different from Healthchecks.io or Cronitor?
CronSafe offers a generous free tier, dead-simple setup (one curl command), and crypto-native payment for Pro. We focus on simplicity: no complex configuration, no agent to install, just a ping URL and instant alerts.
