Dead man's switches, simplified.
Monitor cron jobs, backups, scheduled Workers, and background processes. Get an email before a silent failure becomes a real problem.

Small surface. Strong signal.
Everything needed to catch missing and failed jobs, without an entire incident-management suite.
Email verification
Register without passwords. Every account is verified by email and every monitor stays isolated to its owner.
Failure and recovery
Receive an email when a heartbeat is missed or explicitly fails, then another when it recovers.
One request after every job.
Use the secret ping URL from any language, scheduler, server, or Cloudflare Worker. Report success, failure, or the process exit code.
backup.sh
output=$(./backup.sh 2>&1) # Reports success or the actual exit code curl -d "$output" \ https://heartbeats.dorianmarie.com/ping/SECRET/$?
Your first heartbeat takes a minute.
Verify your email, choose a schedule, and copy the URL.
