Stripe usage alerts for Node apps
Add usage threshold warnings before customers hit surprise limits.
Stripe Usage Alerts Kit is a paid Node source kit for SaaS builders who need monthly usage metering, threshold alerts, invoice usage syncing, and idempotent Stripe webhook handling.
What The Kit Covers
Threshold Logic
Usage events queue billing-period alerts without repeating a warning the customer has already received.
Stripe Webhooks
Raw-body signature checks and event idempotency support invoice, subscription, and usage updates.
Verification
Includes tests, buyer smoke checks, a manifest verifier, and a dependency-free demo server.
Adapt-It-Yourself Source
This is not a hosted usage analytics platform. It is a compact source kit for developers who want a concrete implementation to adapt into an existing Node app, notification system, and Stripe Billing setup.
npm run verify:manifest
npm test
npm run smoke:buyer
The delivered zip includes setup notes, source files, tests, and a checksum manifest.
