Background
Born from the same outage story.
A deploy took billing offline for twelve minutes. Stripe retried, but two events landed during a bad rollout and one never did. Finance reconciled for a week.
The fix was never “handle webhooks better in the controller.” It was a durable buffer, idempotency, and a place to replay after the service recovered. Every mature team eventually builds it, often more than once across microservices.
Marevans packages that layer as a product you deploy once, route every provider through, and operate with the same rigor as the rest of your platform. We focus on the gateway; you keep building what differentiates your business.
