Coming soon
Your cron job died four hours ago. You just found out.
A one-line heartbeat for Vercel Cron, Cloudflare Workers and GitHub Actions — so a job that stops running tells you, instead of waiting for a customer to.
The failure mode nobody watches
Scheduled jobs fail silently. The handler throws, the schedule gets disabled, the token expires — and nothing tells you until something downstream is already wrong.
- Add one line to the end of the job and it checks in when it runs.
- Miss the expected check-in and you get an alert, fast.
- Built for Vercel Cron, Cloudflare Workers and GitHub Actions first, not retrofitted from crontab.
- See the history of runs and the exact time the job stopped reporting.
Who it is for
Small teams running billing, email, sync or cleanup jobs on serverless platforms, without a monitoring stack and without wanting one.
Serverless-first, not an afterthought
The established heartbeat monitors grew up around servers and crontab. This one starts where the jobs now actually run — edge schedules and CI — with a free tier that fits a side project.
Frequently asked questions
How do I add it to a job?
One HTTP request at the end of the job. If the job does not make it, the check-in is missed and you are alerted.
Which platforms are supported at launch?
Vercel Cron, Cloudflare Workers and GitHub Actions are first-class. Plain crontab works too.
Is there a free tier?
Yes — three monitors free for waitlist members at launch.
How fast are the alerts?
Within about a minute of a missed check-in, by email. More channels come later.
When does it launch?
It is in development. You will be emailed the moment it is ready.
