Cron Job Monitor

A dead-man's-switch monitor for scheduled jobs: your cron, backup, or queue worker pings a URL when it runs, and if a ping fails to arrive on schedule you get alerted. Lean and cheap for indies who find Cronitor and Healthchecks overkill.

🎯The Problem

Indies run critical scheduled jobs (nightly DB backups, billing reconciliation, digest emails) with no idea when they silently stop. The classic disaster: the backup cron died three weeks ago, nobody noticed, and the day you need the backup is the day you discover it is empty. Monitors exist, but the popular ones are priced and featured for teams.

💡The Solution

Create a check with an expected schedule (cron expression or interval plus grace period). Your job hits the check's unique ping URL on success. If a ping is late or missing, you get alerted via email, Slack, Telegram, or SMS. Start and finish pings catch jobs that hang rather than just jobs that vanish.

👥Target Users

Solo devs and small teams running cron jobs, backups, queue workers, and scheduled scripts who want monitoring without an enterprise price tag.
