About LocalStack
LocalStack simulates AWS services on your own infrastructure, so developers, CI pipelines and AI agents can build and test cloud and serverless applications without deploying to a real cloud account. The documentation also covers a Snowflake emulation feature.
An open-source core is published on GitHub, and paid tiers with enterprise sales are offered on top. It suits teams that want faster feedback and lower cloud costs while testing infrastructure code and serverless functions.
