Show HN: Fakecloud – Free, open-source AWS emulator

The "real PostgreSQL/Redis behind RDS/ElastiCache" approach is the right call. We run PHP integration tests against SQS and S3, and the biggest pain with mocked services is subtle behavioral differences that only show up in production. Having actual protocol conformance validated against Smithy models is a big deal.

One question: any plans for async event delivery for SNS/EventBridge? In our setup we test fan-out patterns where message ordering and delivery timing matter — curious how Fakecloud handles that vs real AWS eventual consistency.
