AWS SAM Translator is a library that transform SAM templates into AWS CloudFormation templates
Decision gist · record as of 2026-08-14
Yes, if you need to programmatically transform SAM templates or integrate SAM template handling into custom tooling. The library is production-stable, actively maintained, permissively licensed, and has no known vulnerabilities. If you only deploy SAM applications via the CLI, install the SAM CLI instead, which includes this library as a dependency.AI-flagged interpretation of the facts on this page — verify before relying
Before you install
- Requires Python 3.10 or later; boto3 must be installed and configured with AWS credentials for full functionality.
- Low install friction with a pure Python wheel and four lightweight runtime dependencies (boto3, jsonschema, typing_extensions, pydantic).
- Actively maintained with a release from 2026-08-13 and 9563 repository stars.

What it is and what it does
aws-sam-translator is the core library that powers AWS SAM's CloudFormation transformation. It takes SAM template dictionaries and converts them into standard CloudFormation templates, applying best practices like automatic IAM role creation, resource tagging, and syntax extension. The library is the engine behind the SAM CLI's deployment workflow and can be used programmatically to transform templates outside of the CLI context.
The package depends on boto3 for AWS integration, jsonschema for template validation, pydantic for data modeling, and typing_extensions for type hints. It supports Python 3.10 through 3.14 and is actively maintained by AWS, with no known security vulnerabilities. Installation is straightforward via pip with minimal system dependencies.
Use it for
- Programmatically transform SAM templates to CloudFormation for integration into custom deployment pipelines.
- Validate SAM template syntax and structure before deployment using the translator's parsing logic.
- Generate CloudFormation templates from SAM definitions for inspection, documentation, or manual review.
- Build tooling that extends or customizes SAM template transformation behavior.
- Test SAM template transformations in CI/CD workflows without invoking the full SAM CLI.
