What is LocalStack?

LocalStack provides an easy-to-use test/mocking framework for developing Cloud applications. It spins up a testing environment on your local machine that provides the same functionality and APIs as the real AWS cloud environment.

Yes, that's true - you can run your Lambda functions, store data to DynamoDB tables, feed events through Kinesis streams, put your application behind an API Gateway, and much more. And all this happens on your local machine, without ever talking to the cloud.

The diagram below illustrates the efficient dev/test and deployment pipeline enabled by LocalStack.

  1. Your application is developed entirely on the local developer machines. LocalStack provisions all required "cloud" resources in a local container.
  2. Changes are frequently pushed to a continuous integration server that runs the automated tests. LocalStack provisions all required "cloud" resources in the continuous integration server environment.
  3. Once all tests are green, you flip the switch and the application can be seamlessly deployed to the real AWS cloud environment.

Needless to say, this enables an extremely efficient development loop and team collaboration. No more tedious uploading of application code to run a quick test. No more dollars spent on expensive test resources on AWS!

Our users love it. Check out the Github repository, or search on Twitter/Google to find out what people have to say about LocalStack. It's the modern way of developing cloud applications - we hope you're part of it!
