Amazon Web Services (AWS) has released its own AWS Emulator, a local emulator of AWS APIs that allows developers to test their software without calling AWS, eliminating the need for an AWS account. The emulator serves as a local program with an AWS API endpoint, and users can set environment variables to point the AWS CLI or SDK at its endpoint, or pass the emulator's HTTP client to their SDK in embedded mode. The AWS Emulator is free to use, with no additional service fee, and is intended for building and testing purposes only, not for production workloads or security testing. It can be installed and set up using the AWS CLI version 2.35 or higher, and documentation is available in the AWS Emulator User Guide.
