## Summary

AWS has released aws-emulator, an official tool for running tests against a local clone of its many services without a paid API key, according to Simon Willison. The emulator is written in Rust, and the project logged 29,684 commits in its first three weeks. It currently requires Docker to run on macOS or Windows, which the author hopes will change so a single binary can be used across platforms.
