Django Ninja is a free and open source web framework for building REST APIs with Django and Python 3.6+ based type hints. It shares many similarities with FastAPI, another popular Python framework for building APIs. Django Ninja now brings the same methodology to Django users wanting to build modern APIs using OpenAPI (Swagger) standards and JSON schema. It integrates well with the Django ORM and the ecosystem of third-party Django applications. Already the framework is used by multiple companies with live projects.
