AWS Emulator Now Available

AWS Emulator is now available for building and testing AWS applications locally. You can use AWS Emulator to build and test AWS applications on your computer or in your continuous integration (CI) environment. Your existing AWS SDK and CLI calls go to AWS Emulator and come back in milliseconds, so you and your coding agents can find and fix errors locally, with no deployments or AWS account required.

What to do

  • Use AWS Emulator to build and test AWS applications locally.
  • Create and manage resources with the same AWS SDK and AWS CLI calls you use with AWS.
  • Review the AWS Emulator fidelity report to see how its responses compare to AWS.
  • Get started with the AWS Emulator documentation.
