Overview

is a cloud service emulator that runs in a single container on your laptop or in your CI environment. With LocalStack, you can run your AWS applications or Lambdas entirely on your local machine without connecting to a remote cloud provider! Whether you are testing complex CDK applications or Terraform configurations, or just beginning to learn about AWS services, LocalStack helps speed up and simplify your testing and development workflow.

LocalStack supports a growing number of AWS services, like AWS Lambda, S3, Dynamodb, Kinesis, SQS, SNS, and many more! The Pro version of LocalStack supports additional APIs and advanced features. You can find a comprehensive list of supported APIs on our page.

LocalStack also provides additional features to make your life as a cloud developer easier! Check out LocalStack's Cloud Developer Tools for more information.

Requirements

• python (Python 3.6 up to 3.10 supported)
• pip (Python package manager)
• Docker

Installing

The easiest way to install LocalStack is via pip:

pip install localstack

Note: Please do not use sudo or the root user - LocalStack should be installed and started entirely under a local non-root user. If you have problems with permissions in macOS High Sierra, install with pip install --user localstack

It installs the localstack-cli which is used to run the Docker image that hosts the LocalStack runtime.

Example

Start LocalStack inside a Docker container by running:

 % localstack start -d
