AWS has released AWS Emulator, a free local emulator of AWS APIs published under the CC0 license. The emulator was built from 438 API models, and autonomous agents wrote all of its code.

AWS Emulator is a local copy of AWS APIs, released free of charge under CC0. According to the headline, it covers more than 200 AWS services. It is built from 438 API models.

Autonomous AI agents wrote all of the emulator's code. At launch, it passes 56.6% of 42,857 published fidelity tests.

## Why it matters if you build agents

Agent developers can run code that calls AWS services against a local emulator instead of a live account, which can speed up testing.

At launch, slightly more than half of the published fidelity tests pass, so behavior that differs from real AWS should be checked against the live service before the emulator is relied on.
