One silent failure cost us 6 hours of revenue. One alert pays for a year of NotiLens.
Six hours.
That's how long our payment webhook was silently failing before a user messaged us.
Server was up. Endpoint responding. Logs clean. Payments just quietly stopped flowing.
We were running a creator marketplace. Found out from a customer DM, not our tooling.
That night we started building NotiLens - monitoring for the failures that don't throw errors.
What it catches:
Cron ran. Processed 0 records. No error.
AI agent looped 14 times. No output. Credits burning.
Signup flow dead for 4 hours. Misconfigured Cloudflare rule. Revenue just stopped.
None of those showed up in error logs.
Early users are catching the same
broken Zapier nodes, skipped ETL steps, agent loops - all before their users do.
What we built:
Silence detection, broken flow detection, ML anomaly detection, AI agent monitoring, on-call escalation.
Push notifications to iOS and Android. SDKs for Python, Node, Go, Rust, Ruby, PHP, Java.
Would love feedback from anyone running event-driven backends, cross, AI agents, or Stripe payments.
