What it is and what it does

serverless-wsgi is a Serverless Framework plugin that packages and deploys Python WSGI applications to AWS Lambda, making them callable through API Gateway. It transparently converts API Gateway HTTP requests into standard WSGI format, allowing you to run unmodified Flask, Django, or Pyramid applications on Lambda without rewriting your code for a serverless environment.

The plugin handles the operational complexity: it automatically bundles your application's dependencies from requirements.txt, manages werkzeug as a core runtime dependency, and provides local development commands (wsgi serve for testing, wsgi exec for remote Python execution, wsgi manage for Django commands). It supports both API Gateway V1 and V2 payloads and includes convenience CLI commands for remote code execution and framework-specific management tasks.

Use it for

Deploy an existing Flask or Django web application to AWS Lambda without rewriting request/response handling.
Run local development with sls wsgi serve to test your WSGI app before deploying to Lambda.
Execute Django management commands or Flask CLI commands remotely on your deployed Lambda function.
Automatically package and deploy Python dependencies specified in requirements.txt alongside your application.
Handle file uploads, redirects, cookies, and other standard WSGI features transparently on API Gateway.
Execute arbitrary Python or shell code remotely on your Lambda function using wsgi exec or wsgi command.
