cron-job.org alternative
The cron-job.org alternative with missed-run alerts
cron-job.org is a long-running, genuinely free cron service, and for simply firing a URL on a schedule it works. The catch: the interface is dated and there is no heartbeat (missed-run) detection — you only find out about HTTP errors, never about a job that quietly stopped running. Cronmint adds missed-run detection, configurable retries, Slack alerts, and a modern UI.

What cron-job.org is great for
If all you need is to hit a URL every few minutes and you are fine with a bare-bones dashboard, cron-job.org is hard to argue with — it is free and it has been reliable for years. Plenty of small projects run happily on it.
The gap: silent, missed runs
A URL-pinger can only tell you when a request returned an error. It cannot tell you when the request never happened — when your server was down, a deploy removed the schedule, or the job hung. That “it just stopped and nobody noticed” failure is the most common and most damaging one, and it is exactly what heartbeat monitoring catches.
- Heartbeat / missed-run detection: get alerted when an expected run does not arrive.
- Configurable retries so a single blip does not page you.
- Email and Slack alerts with the status code, response body, and timing.
When to upgrade to Cronmint
Once a job actually matters — billing, backups, syncs, digests — “free but blind” stops being a good trade. Cronmint stays cheap ($0 for 5 jobs, $9/mo for Pro) while adding the alerting that turns a cron job from fire-and-hope into something you can trust.

Start freeFrequently asked questions
Is cron-job.org really free?
Yes, cron-job.org is free and has been for a long time. Cronmint also has a free tier (5 jobs); you pay only when you want more jobs, longer history, or shorter intervals.
Why pay when cron-job.org is free?
Because free URL-pinging cannot detect a job that silently stops running. Cronmint’s heartbeat monitoring alerts you on missed runs — the failure mode that actually hurts.
Does Cronmint detect missed runs?
Yes. If a heartbeat does not check in within its expected interval, Cronmint marks the job down and alerts you by email or Slack.
Do I have to migrate my jobs?
No migration tooling needed — recreating a schedule in Cronmint takes about 30 seconds, and you can run both side by side until you are ready to switch.
