Introduction to FastAPI and Django

FastAPI: A modern, high-performance framework designed for building APIs with Python 3.7+ that features automatic documentation, easy data validation, and modern Python type hints.

Django: A full-featured framework suitable for building complex web applications with built-in solutions for ORM, admin panels, and authentication.

Core Features and Advantages

FastAPI:

• High Performance: Comparable to Node.js and Go due to its asynchronous support.
• Rapid Development: Features like automatic documentation and editor support speed up the development process.
• Standards-Based: Fully compatible with OpenAPI and JSON Schema which streamlines API development.

Django:

• Rich Feature Set: Includes an ORM, admin panel, and extensive built-in functionalities.
• Highly Scalable: Ideal for complex applications like CMSs, e-commerce sites, and social networks.
• Strong Community: Benefits from a well-established community and comprehensive documentation.

Performance Comparison

FastAPI excels in scenarios requiring high performance, especially in environments that benefit from asynchronous programming.

Django offers reliable performance for a wide array of web applications, focusing on feature-rich solutions rather than sheer speed.

When to Use Each Framework

Use FastAPI if:

• You need stellar performance for APIs.
• Your project demands rapid development with modern Python features.
• You are building microservices or applications that require efficient real-time data processing.

Use Django if:

• You need a comprehensive solution with less dependency on external libraries.
• Your application requires a rich set of features out-of-the-box.
• You are developing complex systems like content management systems or e-commerce platforms that benefit from Django’s robust security and scalability.
