PulsewatchKnow the moment your cron jobs stop running.
Your backup script pings PulseWatch on every run. The ping stops — you get alerted, in seconds, by email, Telegram or webhook. Uptime checks for your URLs included.

Heartbeat monitors
For cron jobs, queues, backups — anything that should run on a schedule. Your code pings us; silence means trouble. Explicit /fail pings alert instantly.
Uptime monitors
We request your URL as often as every minute. Bad status, timeout or connection failure — confirmed by a retry to avoid flapping — and you're the first to know.

FAQ
How is this different from a normal uptime checker?
Uptime checkers only see what is public. Heartbeat monitoring catches the invisible failures — the backup that silently stopped, the queue worker that crashed at 3am — because your own code confirms every successful run.
What exactly happens when a ping goes missing?
After the expected period the monitor turns "late" (visible in the dashboard, no alert). After period + grace it goes "down" and every attached channel is alerted once. When pings resume you get a recovery alert. No alert spam in between.
Can I get alerts in Slack or Discord?
Yes — add a webhook channel with your Slack or Discord webhook URL. Our payload includes the fields both expect, plus structured JSON for anything custom.
What counts as a monitor?
One heartbeat (one cron job/script) or one uptime check (one URL). Paused monitors still count until you delete them.
Do I need a credit card for the free plan?
No. Free gives you 3 monitors with email alerts, forever. Paid plans are handled by Lemon Squeezy and can be cancelled anytime.
What if PulseWatch itself goes down?
The worker restarts automatically and all state lives in Postgres, so it resumes exactly where it left off. Worst case alerts are delayed by the outage — we are honest about that; monitoring your monitoring is what status pages are for.
