Six monitoring tools compared on the one thing that matters most: do they actually detect silent failures? Heartbeat gaps, broken flows, zero-record cron jobs, AI agent loops — here's what each tool catches and what each misses.
PagerDuty and Incident.io both published comparison posts about each other in 2026. Neither mentioned what small teams and founders actually care about: catching the failures that never create an incident in the first place.
