Django (/ˈdʒæŋɡoʊ/JANG-goh; sometimes stylized asdjango)[5] is afree and open-source,Python-basedweb framework that runs on aweb server. It follows the model–template–views (MTV)architectural pattern.[6][7] It is maintained by theDjango Software Foundation (DSF), an independent organization established in the US as a501(c)(3) non-profit.
Django's primary goal is to ease the creation of complex,database-driven websites. The framework emphasizesreusability and "pluggability" of components, less code,low coupling, rapid development, and the principle ofdon't repeat yourself.[8] Python is used throughout, even for settings, files, anddata models. Django also provides an optional administrativecreate, read, update and delete interface that is generated dynamically throughintrospection and configured via admin models.
Some well-known sites that use Django includeInstagram,[9]Mozilla,[10]Disqus,[11]Bitbucket,[12]Nextdoor,[13] andClubhouse.[14]
Django was created in the autumn of 2003, when theweb programmers at theLawrence Journal-World newspaper,Adrian Holovaty andSimon Willison, began using Python to build applications. Jacob Kaplan-Moss was hired early in Django's development shortly before Willison'sinternship ended.[15] It was released publicly under aBSD license in July 2005. The framework was named after guitaristDjango Reinhardt.[16] Holovaty is aromani jazz guitar player inspired in part by Reinhardt's music.[17]
In June 2008, it was announced that a newly formedDjango Software Foundation (DSF) would maintain Django in the future.[18]
Despite having its own nomenclature, such as naming thecallable objects generating theHTTP responses "views",[6] the core Django framework can be seen as anMVC architecture.[7] It consists of anobject-relational mapper (ORM) that mediates betweendata models (defined as Python classes) and arelational database ("Model"), a system for processing HTTP requests with aweb templating system ("View"), and aregular-expression-basedURL dispatcher ("Controller").
Also included in the core framework are:
The main Django distribution also bundles a number of applications in its "contrib" package, including:

Django's configuration system allows third party code to be plugged into a regular project, provided that it follows the reusable app[21] conventions. More than 5000 packages[22] are available to extend the framework's original behavior, providing solutions to issues the original tool didn't tackle: registration, search,API provision and consumption,CMS, etc.
This extensibility is, however, mitigated by internal components' dependencies. While the Django philosophy implies loose coupling,[23] the template filters and tags assume one engine implementation, and both the auth and admin bundled applications require the use of the internalORM. None of these filters or bundled apps are mandatory to run a Django project, but reusable apps tend to depend on them, encouraging developers to keep using the official stack in order to benefit fully from the apps ecosystem.
Django can be run onASGI orWSGI-compliant web servers.[24] Django officially supports five database backends:PostgreSQL,MySQL,MariaDB,SQLite, andOracle.[25]Microsoft SQL Server can be used with mssql-django.
The Django team will occasionally designate certain releases to be "long-term support" (LTS) releases.[26] LTS releases will get security and data loss fixes applied for a guaranteed period of time, typically 3+ years, regardless of the pace of releases afterwards.

There is a semiannual conference for Django developers and users, named "DjangoCon", that has been held since September 2008. DjangoCon is held annually in Europe, in May or June;[58] while another is held in the United States in August or September, in various cities.[59] The 2012 DjangoCon took place in Washington, D.C., from September 3 to 8. 2013 DjangoCon was held in Chicago at the Hyatt Regency Hotel and the post-conferenceSprints were hosted at Digital Bootcamp, computer training center.[60] The 2014 DjangoCon US returned toPortland, OR from August 30 to 6 September. The 2015 DjangoCon US was held inAustin, TX from September 6 to 11 at the AT&T Executive Center. The 2016 DjangoCon US was held in Philadelphia, PA at TheWharton School of the University of Pennsylvania from July 17 to 22.[61] The 2017 DjangoCon US was held in Spokane, WA;[62] in 2018 DjangoCon US was held in San Diego, CA.[63] DjangoCon US 2019 was held again in San Diego, CA from September 22 to 27. DjangoCon 2021 took place virtually and in 2022, DjangoCon US returned to San Diego from October 16 to 21. DjangoCon US 2023 was held from October 16 to 20 at theDurham, NC convention center and DjangoCon US 2024 is scheduled to return to Durham for September 22 to 27.[64][65]
Django mini-conferences are usually held every year as part of the AustralianPython Conference 'PyCon AU'.[66] Previously, these mini-conferences have been held in:
Django has spawned user groups and meetups around the world, a notable group is theDjango Girls organization, which began in Poland but now has had events in 91 countries.[67][68][69]
Programmers have ported Django's template engine design from Python to other languages, providing decent cross-platform support. Some of these options are more direct ports; others, though inspired by Django and retaining its concepts, take the liberty to deviate from Django's design:
Django as a framework is capable of building a completeCMS. Some dedicated CMS projects are based upon Django:
Django follows this MVC pattern closely enough that it can be called an MVC framework
