Extensions for LocalStack
Decision gist · record as of 2026-08-14
No. The repository is archived and abandoned; the project has been consolidated into a unified LocalStack image. While the package may technically install, there is no active maintenance, and users are explicitly directed to migrate to LocalStack's commercial offerings or the unified image. The unclear license treatment and lack of maintenance support make this unsuitable for new projects.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Docker to be installed and running; requires Python 3.13 (>=3.13,<3.14); the repository is archived and no longer maintained.
- High install friction due to 82 runtime dependencies.
- Repository is archived and marked abandoned as of the latest release, with no active maintenance.

What it is and what it does
localstack-ext is an extension package for LocalStack, the AWS service emulator framework. It builds on localstack-core to provide additional capabilities for developing and testing AWS applications locally without connecting to AWS. The package depends on a large ecosystem of AWS-related libraries (boto3, botocore, aws-encryption-sdk, aws-sam-translator) and infrastructure tools (alembic, dulwich, hypercorn) to support its extensions.
However, the repository is now archived and abandoned as of March 2026. The project has been consolidated into a unified LocalStack image, and this package is read-only. While it may still be installable and functional, there is no active maintenance, bug fixes, or feature development. Users are directed to use LocalStack's commercial offerings or the unified image instead.
Use it for
- Local testing of AWS Lambda, S3, DynamoDB, and other AWS services during development without cloud costs.
- Integration testing of Terraform or CDK applications against a local AWS emulation layer.
- CI/CD pipeline testing where AWS service mocking is needed without external cloud dependencies.
