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 websites such as Fandom, wikiHow, and major internal installations like Intellipedia and Diplopedia.
