The Problem

Cron jobs fail silently. A backup script stops running, and nobody notices for weeks. A billing job fails, and invoices don't send. There's no built-in alerting for 'this job should have run but didn't.'

The Solution

Each cron job pings a unique URL when it completes. If the ping doesn't arrive within the expected schedule, you get an alert via email, Slack, or SMS. Simple dead man's switch pattern.

Target Audience

Backend developers and DevOps teams running scheduled jobs (cron, Celery, Sidekiq) who need to know immediately when a job fails silently

Why Now?

Serverless and microservices mean more scheduled jobs than ever. Each Lambda, Cloud Function, and cron needs monitoring. Silent failures cost businesses thousands before detection.

Revenue Model

SaaS: Free (5 jobs), $9/mo Starter (20 jobs, Slack alerts), $29/mo Pro (100 jobs, SMS, API), $79/mo Team (unlimited, multi-team, SLA).
