Django REST framework

Django REST framework (DRF) is a powerful and flexible toolkit for building Web APIs. It's built on top of the Django web framework, leveraging its strengths like the ORM, admin interface, and robust security features, while extending it specifically for API development. DRF simplifies common API tasks such as data serialization, request parsing, authentication, and access control, allowing developers to focus on business logic rather than boilerplate.

The framework provides a comprehensive set of tools, including serializers that handle data validation and conversion between Python objects and various data formats (like JSON and XML), and generic class-based views that abstract away common API patterns. Its 'Browsable API' feature is particularly noteworthy, offering a user-friendly web interface for interacting with the API directly in the browser, which greatly aids development and testing. DRF's modular design ensures it's highly customizable, enabling developers to tailor every aspect of their API to specific project requirements.
