AWS Releases Free Local Cloud Emulator Built by AI Agents

Nov 11, 2026
AWS Emulator simulates more than 200 cloud services on local machines, letting developers and coding agents test software without network access or cloud fees.

Amazon Web Services released AWS Emulator, a free tool built entirely by autonomous AI agents, according to GeekWire. It simulates AWS services on a local machine so developers and coding agents can test software without network access or cloud fees.

The emulator uses more than 400 API models covering over 200 AWS services. AWS said its engineers did not write or review its code. Agents use public API models, compare tests against the AWS cloud, identify failures and fix issues through automated security and coding checks.

The project began when an engineer prompted the Kiro coding agent to build a version of Amazon SQS. Kiro produced an initial version in 15 minutes and expanded it to cover other AWS services over one weekend.

AWS released the emulator under the CC0 public domain dedication and published its commit history on GitHub. An IDC analyst told InfoWorld that it does not yet simulate throttling, outages or regional service differences, and that it does not sandbox the code it runs.
