# AWS Emulator — AI Coding Tool Review & Pricing

> AWS Emulator is a local emulator of the AWS APIs that you run on your machine, a development server or in CI. The AWS CLI, AWS SDKs and coding agents talk to it over a local HTTPS endpoint with the same API shapes and errors as AWS, so they can create resources, check results and iterate without an AWS account or a deployment.

## At a glance

- **Tool**: AWS Emulator
- **Company**: Amazon Web Services
- **Category**: [AI Testing & Quality Assurance](https://ai.dosa.dev/category/qa-testing)
- **Pricing model**: Free
- **Official website**: https://docs.aws.amazon.com/emulator/latest/userguide/what-is-service.html

## Key features

- Local HTTPS endpoint (127.0.0.1:9297) for the AWS CLI and any AWS SDK
- Built from the same AWS API models as the SDKs, so requests and errors match AWS
- aws-emulator agent skill installed with `aws agent-toolkit add-skill` (AWS CLI 2.35.0 or later)
- Embedded mode for Rust tests with one isolated emulator per test
- Per-service fidelity scores published with each release
- Generates its own credentials, config and certificate on start
- RPM and Debian packages on Linux, Docker on macOS and Windows

## Pricing

**Model**: Free

AWS Emulator has no additional service fee and its source is released under CC0-1.0. You pay only for AWS resources when you deploy to AWS.

## Who it is for

- **Best for**: Developers and coding agents that need to build and test AWS applications in a fast local loop or in CI without touching a real AWS account.
- **Not ideal for**: Production workloads or security testing, which AWS says the emulator is not for, and projects that rely on APIs it does not yet emulate faithfully.

## Verdict

An official, free local AWS emulator with first-class coding-agent support; a strong default for agent-driven AWS development and testing.

## Recent updates

Launched on November 11, 2026; AWS says the code was written entirely by autonomous AI agents, and releases ship several times a day (v1.0.336 on November 12, 2026).
