LocalStack

LocalStack simulates cloud environments on customer infrastructure so developers and AI agents can validate cloud applications before deployment. It currently emulates AWS and Snowflake, with AWS coverage listed at 120+ services; an Azure public preview is described as coming soon. Developers can place application code and infrastructure-as-code resources in a local container, review failures, validate fixes, and change the endpoint when ready to ship. It can run in GitHub Actions, GitLab CI, CircleCI, and Jenkins using a Docker image. Listed infrastructure-as-code tools include CDK, Terraform, and Pulumi, and the Hobby plan lists an Extensions Marketplace and VS Code integration. LocalStack is intended for development and testing, not production customer-facing applications. Hobby is free for non-commercial use and includes 30+ emulated services and one personal sandbox. AWS Base is listed at 39.00 USD per year, billed at $39 per license per month annually, or $45 monthly. AWS Base includes 55+ emulated services and 100 minutes of workspace previews per month. LocalStack supports API, Linux, macOS, self-hosted, web, and Windows environments.
