How do I send a heartbeat?
Make a POST request to your unique endpoint URL. Works with curl, any HTTP library, or any language. No SDK, no dependencies.
What counts as a monitor?
Each cron job, webhook, or scheduled task you want to watch is one monitor. Create as many as your plan allows.
What happens when an alert fires?
You get an email immediately. Once your job pings again, the alert resets automatically — no action needed.
Is there an SDK?
No SDK required. Any HTTP POST request works. We keep it simple on purpose.
Can I use this for uptime monitoring?
Heartbeat is for scheduled and background tasks, not HTTP uptime checks. For uptime monitoring, use something like UptimeRobot alongside us.
