LocalStack

LocalStack provides a local cloud development platform that emulates AWS, Snowflake and, in public preview, Azure services. Its containerized emulator runs on customers' own infrastructure, including laptops, CI/CD runners and shared internal environments, so developers and AI agents can deploy and test cloud applications without provisioning cloud resources.

The product is sold to software development and platform/DevOps teams on per-license subscription tiers (Base, Ultimate and custom Enterprise), with a free Hobby tier for non-commercial use and purchase through AWS Marketplace. The website cites case studies from companies including FABR, Neurolytics and CartonCloud.

The company's legal entity is LocalStack GmbH, with a registered address in Zürich, Switzerland. Its website lists its first open source commits in August 2016, a $25M Series A raised in November 2024, and 90+ employees working remotely across 14+ countries. Current open roles include engineering, DevOps, support, product and sales positions in the United States, Canada, the United Kingdom, Spain, Poland, Portugal and Brazil.
