CronWatch

Your cron jobs fail silently.
We tell you immediately.

CronWatch monitors scheduled jobs across every platform and alerts you the moment a job misses its window, errors, or stops running.

No credit card. No spam. Notify me when it launches.

The Friday invoice email problem

It's Monday morning. Your nightly data sync stopped running Thursday. You find out from a user.

Without CronWatch
❌ nightly-sync: last run Thu 3am — then nothing
❌ No alert. No error. Just silence.
❌ Customer: "Why is my dashboard 4 days stale?"
❌ 3 hours debugging: it was a permissions change on the DB user
❌ Lost: 4 days of processed data, 1 customer's trust
With CronWatch
✅ Thursday 3:05am: "nightly-sync missed its 3am window"
✅ Alert in Slack within 5 minutes of missed window
✅ Fixed by 3:30am — before any customer noticed
✅ Total downtime: 30 minutes, not 4 days

⏰

Missed window alerts

Define expected run windows. Get alerted within minutes if a job doesn't run. Never find out from a customer again.

💥

Error detection

Capture non-zero exit codes and exceptions. Know what failed and why — not just that something stopped running.

🔌

Works everywhere

One ping URL. Add one line to any cron job — shell, Python, Node, Ruby, whatever runs your job.

📢

Alert anywhere

Slack, email, PagerDuty, webhooks. Deliver alerts to wherever your team actually sees them.

📈

Run history

See every run: duration, success/failure, exit code. Spot drift before it becomes an incident.

🔒

Simple integration

Heartbeat ping model — add curl https://cron.watch/ping/your-job-id to the end of your cron. 30 seconds to integrate.

Works with every job scheduler
