LocalStack
LocalStack 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!
About LocalStack
LocalStack is a local cloud development platform that emulates cloud provider APIs so applications can be built, tested, and validated without provisioning real cloud infrastructure. It runs as a container on local infrastructure, including developer laptops, CI/CD runners, or centralized shared infrastructure, and simulates the actual APIs of supported cloud providers. Coverage includes AWS (120+ services) and Snowflake, with support for Microsoft Azure listed as coming soon.
The platform lets code deploy to a local container simulating a production environment, surfacing defects and failures before code reaches the cloud, and gives instant feedback when code is updated and redeployed to the container. Once validated, teams update the endpoint to ship code to a staging or production environment.
LocalStack is aimed at software development teams and AI coding agents that need to test and debug cloud application behavior without cloud access, provisioning delays, or cloud costs, including replacing shared cloud test environments with local ones for individual developers.
