Kind: launch · Impact: medium

## In brief

- AWS launched AWS Emulator, a local emulator for AWS services that runs on a developer's machine.
- The AWS CLI, AWS SDKs and coding agents connect to it over a local HTTPS endpoint using the same AWS APIs they would use in the cloud.
- According to The New Stack, the emulator was built entirely by a team of agents and AWS will maintain it.

## Why it matters

Developers can test AWS-dependent applications locally against an emulated AWS API without deploying to the cloud, which may affect demand for third-party emulators such as LocalStack.
