Summary

LocalStack simulates cloud environments on customer infrastructure so developers and AI agents can validate applications before deployment. It currently emulates AWS and Snowflake, with AWS coverage described as more than 120 services; an Azure public preview is coming soon. Developers can deploy application code and infrastructure-as-code resources into a local container, review failures, validate fixes and then change the endpoint when ready to ship. LocalStack can run in GitHub Actions, GitLab CI, CircleCI and Jenkins using a Docker image. Listed infrastructure-as-code tools include CDK, Terraform and Pulumi. The free Hobby plan includes 30+ emulated services and one personal sandbox, but is limited to non-commercial use. AWS Base is 39.00 USD per year, billed at $39 per license per month annually, or $45 per license per month billed monthly. LocalStack is intended for development and testing, not production customer-facing applications. Enterprise lists custom SSO and SCIM, GovCloud and offline or air-gapped image delivery options.
