Zappa
Serverless Python Web Services
Overview
Zappa is a tool that makes it easy to build and deploy server-less, event-driven Python applications (including, but not limited to, WSGI web apps) on AWS Lambda and API Gateway. It handles all of the configuration and deployment automatically, so you can focus on your code.
✨ Key Features
- Deploy existing Python web apps (Flask, Django) to Lambda
- Automatic deployment and configuration
- Scheduled function execution
- Custom domains and SSL
- Rollbacks and rollforwards
🎯 Key Differentiators
- Focus on deploying existing Python web applications to a serverless environment.
- Simple and easy to use.
- Automatic configuration and deployment.
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.
