AWS Emulator, Amazon‘s new developer tool, puts a working stand-in for its cloud on an ordinary computer, so software that normally talks to Amazon’s servers can be tested offline, for free and without an account. The surprise is who built it. Amazon says AI agents wrote every line, and the engineers on the project have not written or reviewed any of the code.
For people who build software, that changes a slow and expensive habit. Testing an app against the real cloud means waiting on servers and paying for resources that exist only to be thrown away. Coding agents such as Amazon’s Kiro and Anthropic‘s Claude Code make the problem worse, because they check their work by running code over and over, and every round trip to the cloud adds delay and cost.
