MediaWiki

MediaWiki is a free and open-source wiki software. It is used on Wikipedia and almost all other Wikimedia websites, including Wiktionary, Wikimedia Commons and Wikidata; these sites define a large part of the requirement set for MediaWiki.[5] It was developed for use on Wikipedia in 2002, and given the name "MediaWiki" in 2003.[6] MediaWiki was originally developed by Magnus Manske and improved by Lee Daniel Crocker.[7][8] Its development has since then been coordinated by the Wikimedia Foundation.

MediaWiki is written in the PHP programming language and stores all text content into a database. The software is optimized to efficiently handle large projects, which can have terabytes of content and hundreds of thousands of views per second.[5][9] Because Wikipedia is one of the world's largest websites, achieving scalability through multiple layers of caching and database replication has been a major concern for developers. Another major aspect of MediaWiki is its internationalization; its interface is available in more than 300 languages.[10] The software has more than 1,000 configuration settings[11] and more than 1,800 extensions available for enabling various features to be added or changed.[12]

Besides its use on Wikimedia sites, MediaWiki has been used as a knowledge management and content management system on tens of thousands of websites, and thousands of companies, public and private, including the websites Fandom, wikiHow, and major internal installations like Intellipedia and Diplopedia.
