Who This Tool Is For
Platform teams using CloudFormation registry extensions or custom Hooks.
Why We Built This Tool
Native AWS::* stacks are free of CFN fees; third-party handlers and custom hooks are metered.
What Problem It Solves
- Daily ops. 500 resources × daily ops ≈ 15K handlers/mo.
- Hook fan-out. Many hooks × stack ops multiplies invocations.
- Slow handlers. Duration past 30s/op adds overage.
