Фреймворк Django REST был создан, как гибкий инструментарий для создания веб-API на основе Django.

DRF использовался многими компаниями, включая Mozilla, Red Hat и Eventbrite.

Это был один из первых примеров **автоматического документирования API** и это была одна из первых идей, вдохновивших на создание **FastAPI**.
