Fakecloud: Local AWS cloud emulator for integration tests

Fakecloud is a local AWS cloud emulator that allows developers to run integration tests using standard AWS SDKs and clients without needing accounts or paid plans. It supports 105 AWS services with 100% API conformance and includes purpose-built SDKs for TypeScript, Python, Go, PHP, Java, and Rust to enable test inspection and control of async behavior. Unlike alternatives, fakecloud runs as a simple local binary with realistic cross-service integrations and no authentication requirements.
