Amazon says AI agents built an entire product. The company has released AWS Emulator, a tool that runs copies of Amazon’s cloud services on a developer’s own machine. Developers use it for testing.

Amazon says the emulator was 100% written by autonomous AI agents. Its statement is direct: “Our team hasn’t written or reviewed any of the code.”

Hundreds of agents work on the project at once. Tens of thousands of tests check their output. The tool is free under an open license, CC0.

Early testers have found gaps. Heise reports more than 70 issues on GitHub. Some requests that real AWS rejects succeed in the emulator.

Amazon’s post is dated November 11. Heise’s report is dated November 12.

“Our team hasn't written or reviewed any of the code.”
