Django REST framework was created to be a flexible toolkit for building Web APIs using Django underneath, to improve its API capabilities.

It is used by many companies including Mozilla, Red Hat and Eventbrite.

It was one of the first examples of **automatic API documentation**, and this was specifically one of the first ideas that inspired "the search for" **FastAPI**.

### <a href="https://www.django-rest-framework.org/" class="external-link" target="_blank">Django REST Framework</a>

Django REST Frameworkは、Djangoを下敷きにしてWeb APIを構築する柔軟なツールキットとして、APIの機能を向上させるために作られました。

Mozilla、Red Hat、Eventbrite など多くの企業で利用されています。

これは**自動的なAPIドキュメント生成**の最初の例であり、これは**FastAPI**に向けた「調査」を触発した最初のアイデアの一つでした。

!!! note "備考"
    Django REST Framework は Tom Christie によって作成されました。StarletteとUvicornの生みの親であり、**FastAPI**のベースとなっています。

never forgotten that, if you drink much from a bottle marked
