Your cron jobs are failing silently right now.
CronSafe alerts you when scheduled jobs don't run — before your customers notice. Dead man's switch monitoring for engineers who can't afford silent failures.
# Add this to your cron job — that's it

Silent Failures
Jobs exit 0 but fail to process data. No alerts. No logs. Just stale output.
Missed Executions
Server rebooted. Daemon crashed. Job didn't run. You found out when a customer complained.
Duration Drift
Your nightly sync used to take 30 seconds. Now it takes 40 minutes. Nobody noticed.
Three steps. One line of code.
Add one line to your job
Append a curl ping to the end of your cron script.
Configure your schedule
Tell CronSafe when to expect the next check-in (cron expression or interval).

Receive a Slack, email, or webhook alert if your job is late, long, or missing.
