Zappa
Serverless Python Web Services
Overview
Zappa is a tool that makes it incredibly easy to build and deploy server-less, event-driven Python applications (including, but not limited to, WSGI web apps) on AWS Lambda + API Gateway. It handles all the configuration and deployment automatically. This allows you to take existing Python web applications built with frameworks like Flask or Django and deploy them in a serverless environment with minimal code changes.
✨ Key Features
- Deploys any Python WSGI application
- Compatible with popular frameworks like Flask and Django
- Automatic deployment and configuration
- Rollback capabilities
- Scheduled function execution
- CLI-based workflow
🎯 Key Differentiators
- Focus on deploying existing WSGI applications with minimal changes.
- Supports a wide range of Python web frameworks.
- Simplicity for developers already familiar with Flask/Django.
Unique Value: Go serverless with your existing Python web apps in minutes, without rewriting your code.
🎯 Use Cases (3)
✅ Best For
- Deploying a Flask REST API on AWS Lambda
- Running a Django application in a serverless environment
- Creating a simple webhook handler using a familiar Python framework
💡 Check With Vendor
Verify these considerations match your specific requirements:
- Non-WSGI or non-Python applications
- Applications that are not a good fit for the Lambda execution model (e.g., long-running connections)
- Projects that require fine-grained control over AWS resources
🏆 Alternatives
Unlike Chalice, which is a microframework for new apps, Zappa is designed to deploy existing, larger applications. It's more specialized for this purpose than the more general-purpose Serverless Framework.
