What is CronSafe?

CronSafe monitors your cron jobs, scheduled tasks, and background workers using a dead man's switch (heartbeat) pattern. If your job doesn't ping CronSafe within the expected interval, you get alerted instantly via Slack, email, or webhook.

Key features:

  • Dead man's switch monitoring (heartbeat pattern)
  • Explicit fail endpoint to report errors
  • Overlap detection (alerts if a job starts before the previous one finishes)
  • Job output capture directly in Slack alerts
  • Escalating reminders and configurable grace periods
  • Weekly summary reports
  • 20 monitors free, unlimited at €9/month flat
  • EU-hosted (Hetzner, Germany), GDPR compliant
  • Simple integration: just add a curl ping to the end of your script

CronSafe was built after a backup script silently stopped running for 11 days at a client project. Nobody noticed until they needed a restore. Whether you use cron, systemd timers, Kubernetes CronJobs, GitHub Actions, or any scheduler — CronSafe makes sure your jobs actually run.
