AWS releases free local emulator built entirely by AI agents
AWS has released a free tool called AWS Emulator for developers who build apps using its cloud services.
It runs on a developer’s own computer, so they can test code without an AWS account, cloud resources or a network connection.
The emulator covers hundreds of AWS services, using 438 API models, though how closely it matches AWS varies by service and operation.
Coding agents can produce code quickly, but testing it against the real cloud can take time and add costs.
AI agents wrote and maintain all the emulator’s code, testing it against AWS, finding gaps and making fixes.
The tool is meant for development and testing, not for production or security checks, and its data disappears when it stops.
AWS publishes fidelity scores and tests, and says the emulator is updated several times a day.
AWS released AWS Emulator on Nov. 11, a free tool that simulates AWS services on a developer’s computer.
It lets developers test AWS applications locally without an AWS account, cloud resources or network connection.
The emulator is based on 438 AWS API models and supports interfaces for hundreds of services, though its coverage varies by service and operation.
AWS says autonomous AI agents wrote and maintain all of its code, while agents test it against real AWS and fix problems.
AWS says the tool is not intended for production use, and warns against using it for security testing.
- Who
- Amazon Web Services (AWS) released the tool. AWS senior principal engineer Matt Goldberg led its development.
- What
- AWS Emulator locally simulates AWS APIs so developers can build and test applications without using cloud resources.
- When
- AWS announced it on Nov. 11, 2026, local time.
- Where
- It runs on a developer’s own computer. The source code is available on GitHub.
- Why
- It allows developers and AI coding agents to test AWS applications locally, without cloud costs or delays.
This story does not have two clearly opposing sides.
An Anthropic team demonstrated a C compiler built by a team of Claude agents, inspiring Goldberg’s experiment.
Goldberg prompted AWS’s Kiro coding agent to create a passable version of Amazon SQS in about 15 minutes.

What people are saying
The emulator was written entirely by autonomous agents. Our team hasn’t written or reviewed any of the code.
I think agents also need coloring books.
