Fakecloud: Local AWS cloud emulator for integration tests
a day ago
- fakecloud is a local AWS emulator designed for integration tests, letting apps use normal AWS clients while staying fully local.
- It achieves true 100% conformance with 248,557/248,557 Smithy-model-generated test variants passing across 46 services and 7,508 operations.
- Unlike LocalStack Community, fakecloud requires no account, auth token, or paid plan—no Docker needed, just a ~19 MB binary or Docker image, with ~300ms startup and ~10 MiB idle memory.
- Offers SDKs for TypeScript, Python, Go, PHP, Java, and Rust to inspect and control emulated services (e.g., SES emails, SNS messages, Lambda invocations) and force async behaviors on demand.
