Heartbeat monitors your critical events and alerts you when they stop. Perfect for cron jobs, webhooks, backups, and any process that should run regularly.

  • Simple POST endpoint

How It Works

1. Create a Rule

Enter your email and set a timeout (how long before we alert you). You'll get a unique endpoint URL.

2. Send Heartbeats

Add a simple POST request to your cron job or script. Just hit your endpoint URL whenever your task runs.

curl -X POST https://your-endpoint-url

3. Get Alerted

If we don't hear from you within your timeout window, you'll get an email alert. Simple as that.

Why I Built This

I got tired of my cron jobs failing silently. Backups that stopped running, webhooks that died quietly, scheduled tasks that just... disappeared. Existing solutions were either too complex or too expensive for simple monitoring needs. So I built Heartbeat — a dead simple way to know when things stop working.
