Powertools for AWS Lambda (Python) is a developer toolkit to implement Serverless best practices and increase developer velocity.

  • Features

    Adopt one, a few, or all industry practices. Progressively.

    All features

  • ❤ Support this project

    Become a public reference customer, share your work, contribute, use Lambda Layers, etc.

    Support

  • Available languages

    Powertools for AWS Lambda is also available in other languages

    Java, TypeScript, and .NET

Install

You can install Powertools for AWS Lambda (Python) using your favorite dependency management, or Lambda Layers:

Most features use Python standard library and the AWS SDK (boto3) that are available in the AWS Lambda runtime.

  • pip: pip install "aws-lambda-powertools"📋
  • poetry: poetry add "aws-lambda-powertools"📋
  • pdm: pdm add "aws-lambda-powertools"📋

Extra dependencies

However, you will need additional dependencies if you are using any of the features below:

Feature Install Default dependency
Tracer pip install "aws-lambda-powertools[tracer]"📋 aws-xray-sdk
Validation pip install "aws-lambda-powertools[validation]"📋 fastjsonschema
Parser pip install "aws-lambda-powertools[parser]"📋 pydantic (v2)
Data Masking pip install "aws-lambda-powertools[datamasking]"📋 aws-encryption-sdk, jsonpath-ng
All extra dependencies at once pip install "aws-lambda-powertools[all]"📋
Two or more extra dependencies only, not all pip install "aws-lambda-powertools[tracer,parser,datamasking"]📋

Lambda Layer is a .zip file archive that can contain additional code, pre-packaged dependencies, data, or configuration files. We compile and optimize all dependencies, and remove duplicate dependencies already available in the Lambda runtime to achieve the most optimal size.

For the latter, make sure to replace {region} with your AWS region, e.g., eu-west-1, and the {python_version} without the period (.), e.g., python313 for Python 3.13.

Architecture Layer ARN
x86_64 arn:aws:lambda:{region}:017000801446:layer:AWSLambdaPowertoolsPythonV3-{python_version}-x86_64:4📋
ARM arn:aws:lambda:{region}:017000801446:layer:AWSLambdaPowertoolsPythonV3-{python_version}-arm64:4📋

You can add our layer using the AWS Lambda Console (direct link):

  • Under Layers, choose AWS layers or Specify an ARN
  • Click to copy the correct ARN value based on your AWS Lambda function architecture and region

Are we missing a framework? please create a documentation request.

Thanks to the community, we've covered most popular frameworks on how to add a Lambda Layer to an existing function.

You can use AWS CLI to generate a pre-signed URL to download the contents of our Lambda Layer.

AWS CLI command to download Lambda Layer content
1
aws lambda get-layer-version-by-arn --arn arn:aws:lambda:eu-west-1:017000801446:layer:AWSLambdaPowertoolsPythonV3-python312-x86_64:4 --region eu-west-1

You'll find the pre-signed URL under Location key as part of the CLI command output.

We provide a SAR App that deploys a CloudFormation stack with a copy of our Lambda Layer in your AWS account and region.

Compared with the public Layer ARN option, the advantage is being able to use a semantic version.

App ARN

Every morning during business days (~8am UTC), we publish a prerelease to PyPi to accelerate customer feedback on unstable releases / bugfixes until they become production ready.

Here's how you can use them:

Local development

Using Lambda Layer? Simply add "aws-lambda-powertools[all]"📋 as a development dependency.

Powertools for AWS Lambda (Python) relies on the AWS SDK bundled in the Lambda runtime. This helps us achieve an optimal package size and initialization. However, when developing locally, you need to install AWS SDK as a development dependency to support IDE auto-completion and to run your tests locally:

A word about dependency resolution

In this context, [aws-sdk] is an alias to the boto3 package. Due to dependency resolution, it'll either install:

Lambda Layer

Lambda Layer is a .zip file archive that can contain additional code, pre-packaged dependencies, data, or configuration files. We compile and optimize all dependencies for Python versions from 3.8 to 3.13, as well as for both arm64 and x86_64 architectures, to ensure compatibility. We also remove duplicate dependencies already available in the Lambda runtime to achieve the most optimal size.

aws lambda get-layer-version-by-arn --arn arn:aws:lambda:eu-west-1:017000801446:layer:AWSLambdaPowertoolsPythonV3-python312-x86_64:4 --region eu-west-1

SAR

Serverless Application Repository (SAR) App deploys a CloudFormation stack with a copy of our Lambda Layer in your AWS account and region.

Compared with the public Layer ARN option, SAR allows you to choose a semantic version and deploys a Layer in your target account.

App ARN Description
aws-lambda-powertools-python-layer arn:aws:serverlessrepo:eu-west-1:057560766410:applications/aws-lambda-powertools-python-layer📋 Contains all extra dependencies (e.g: pydantic).
aws-lambda-powertools-python-layer-arm64 arn:aws:serverlessrepo:eu-west-1:057560766410:applications/aws-lambda-powertools-python-layer-arm64📋 Contains all extra dependencies (e.g: pydantic). For arm64 functions.
Click to expand and copy SAR code snippets for popular frameworks

You can create a shared Lambda Layers stack and make this along with other account level layers stack.

sam init --app-template hello-world-powertools-python --name sam-app --package-type Zip --runtime python3.11 --no-tracing

Features

Core utilities such as Tracing, Logging, Metrics, and Event Handler will be available across all Powertools for AWS Lambda languages. Additional utilities are subjective to each language ecosystem and customer demand.

Utility Description
Tracing Decorators and utilities to trace Lambda function handlers, and both synchronous and asynchronous functions
Logger Structured logging made easier, and decorator to enrich structured logging with key Lambda context details
Metrics Custom Metrics created asynchronously via CloudWatch Embedded Metric Format (EMF)
Event handler: AppSync AppSync event handler for Lambda Direct Resolver and Amplify GraphQL Transformer function
Event handler: API Gateway, ALB and Lambda Function URL Amazon API Gateway REST/HTTP API and ALB event handler for Lambda functions invoked using Proxy integration, and Lambda Function URL
Middleware factory Decorator factory to create your own middleware to run logic before, and after each Lambda invocation
Parameters Retrieve parameter values from AWS Systems Manager Parameter Store, AWS Secrets Manager, or Amazon DynamoDB, and cache them for a specific amount of time
Batch processing Handle partial failures for AWS SQS batch processing
Typing Static typing classes to speedup development in your IDE
Validation JSON Schema validator for inbound events and responses
Event source data classes Data classes describing the schema of common Lambda event triggers
Parser Data parsing and deep validation using Pydantic
Idempotency Idempotent Lambda handler
Data Masking Protect confidential data with easy removal or encryption
Feature Flags A simple rule engine to evaluate when one or multiple features should be enabled depending on the input
Streaming Streams datasets larger than the available memory as streaming data.

Environment variables

Info

Explicit parameters take precedence over environment variables

Environment variable Description Utility Default
POWERTOOLS_SERVICE_NAME Sets service name used for tracing namespace, metrics dimension and structured logging All "service_undefined"
POWERTOOLS_METRICS_NAMESPACE Sets namespace used for metrics Metrics None
POWERTOOLS_TRACE_DISABLED Explicitly disables tracing Tracing false
POWERTOOLS_TRACER_CAPTURE_RESPONSE Captures Lambda or method return as metadata. Tracing true
POWERTOOLS_TRACER_CAPTURE_ERROR Captures Lambda or method exception as metadata. Tracing true
POWERTOOLS_TRACE_MIDDLEWARES Creates sub-segment for each custom middleware Middleware factory false
POWERTOOLS_LOGGER_LOG_EVENT Logs incoming event Logging false
POWERTOOLS_LOGGER_SAMPLE_RATE Debug log sampling Logging 0
POWERTOOLS_LOG_DEDUPLICATION_DISABLED Disables log deduplication filter protection to use Pytest Live Log feature Logging false
POWERTOOLS_PARAMETERS_MAX_AGE Adjust how long values are kept in cache (in seconds) Parameters 5
POWERTOOLS_PARAMETERS_SSM_DECRYPT Sets whether to decrypt or not values retrieved from AWS SSM Parameters Store Parameters false
POWERTOOLS_DEV Increases verbosity across utilities Multiple; see POWERTOOLS_DEV effect below false
POWERTOOLS_LOG_LEVEL Sets logging level Logging INFO

Optimizing for non-production environments

We will emit a warning when this feature is used to help you detect misuse in production.

Whether you're prototyping locally or against a non-production environment, you can use POWERTOOLS_DEV to increase verbosity across multiple utilities.

When POWERTOOLS_DEV is set to a truthy value (1, true), it'll have the following effects:

Utility Effect
Logger Increase JSON indentation to 4. This will ease local debugging when running functions locally under emulators or direct calls while not affecting unit tests.

However, Amazon CloudWatch Logs view will degrade as each new line is treated as a new message.
Event Handler Enable full traceback errors in the response, indent request/responses, and CORS in dev mode (*).
Tracer Future-proof safety to disables tracing operations in non-Lambda environments. This already happens automatically in the Tracer utility.

Debug mode

As a best practice for libraries, Powertools module logging statements are suppressed.

When necessary, you can use POWERTOOLS_DEBUG environment variable to enable debugging. This will provide additional information on every internal operation.

Using Lambda Layers

Layers help us understand who uses Powertools for AWS Lambda (Python) in a non-intrusive way.

When using Layers, you can add Powertools for AWS Lambda (Python) as a dev dependency to not impact the development process. For Layers, we pre-package all dependencies, compile and optimize for storage and both x86_64 and ARM architecture.

Tenets

These are our core principles to guide our decision making.

  • AWS Lambda only. We optimise for AWS Lambda function environments and supported runtimes only. Utilities might work with web frameworks and non-Lambda environments, though they are not officially supported.
  • Eases the adoption of best practices. The main priority of the utilities is to facilitate best practices adoption, as defined in the AWS Well-Architected Serverless Lens; all other functionality is optional.
  • Keep it lean. Additional dependencies are carefully considered for security and ease of maintenance, and prevent negatively impacting startup time.
  • We strive for backwards compatibility. New features and changes should keep backwards compatibility. If a breaking change cannot be avoided, the deprecation and migration process should be clearly defined.
  • We work backwards from the community. We aim to strike a balance of what would work best for 80% of customers. Emerging practices are considered and discussed via Requests for Comment (RFCs)
  • Progressive. Utilities are designed to be incrementally adoptable for customers at any stage of their Serverless journey. They follow language idioms and their community’s common practices.
