Free open-source local AWS emulator
About
- A free open-source emulator that can fully reproduce an AWS environment locally, developed as an alternative to LocalStack, which became paid
- Runs 34 AWS services on a single port and actually runs Postgres, Redis, and Docker containers, providing an infrastructure-level test environment
- Fully compatible with the AWS SDK, CLI, Terraform, CDK, Pulumi, and more, and distributed under the MIT license with no account registration or telemetry
- Light and fast local execution with a 2-second startup, 30MB memory usage, and a 150MB Docker image
- All features are provided for free, so you can build a complete local AWS development environment that replaces LocalStack Pro features
