Runaway serverless functions can cause unexpected high bills, with no automatic circuit breaker to prevent this.
Real Demand Evidence
Found on hackernews ↗·2 months ago
I deployed a Lambda function with a bug and got a $4,200 bill in six hours. AWS sent me an email but by the time I saw it the damage was done. I need something that just kills the function.
Core Insight
A circuit breaker service that automatically stops serverless execution based on real-time spend rate.
- Target Customer

Competitive Landscape
Require manual configuration per-function and don't respond to cost signals
Willingness to Pay
- $19–$49/mo
AWS bill shock stories with $1K–$10K unexpected charges are common on r/aws; a circuit breaker service at $19–$49/mo would provide immediate ROI after preventing even one runaway function incident.
