# Django REST framework
**A toolkit for building well-connected, self-describing web APIs.**
**Author:** Tom Christie. [Follow me on Twitter][twitter]
[![build-status-image]][travis]
---
**Full documentation for REST framework is available on [http://django-rest-framework.org][docs].**
Note that this is the 2.0 version of REST framework. If you are looking for earlier versions please see the [0.4.x branch][0.4] on GitHub.
---
# Overview
Django REST framework is a lightweight library that makes it easy to build Web APIs. It is designed as a modular and easy to customize architecture, based on Django's class based views.
Web APIs built using REST framework are fully self-describing and web browseable - a huge useability win for your developers. It also supports a wide range of media types, authentication and permission policies out of the box.
If you are considering using REST framework for your API, we recommend reading the [REST framework 2 announcment][rest-framework-2-announcement] which gives a good overview of the framework and it's capabilities.
There is also a sandbox API you can use for testing purposes, [available here][sandbox].
