Flatline Gives Silent Failures Somewhere to Scream

Why it surfaced

Flatline targets the failure mode ordinary cron monitors miss: an AI agent or unattended job that remains technically alive but quietly stops making progress. Add one ping request, define the expected schedule and grace period, then route missed-heartbeat alerts to email, Slack, Discord, SMS, or a phone call.

A dead-man's-switch monitoring service for cron jobs, automations, and AI agents that alert when expected check-ins stop.
