Power your website with the free, web-based wiki software that runs Wikipedia and the other sites of its developer, Wikimedia Foundation. Written in PHP and using a back-end database, MediaWiki is optimized to correctly scale and efficiently handle projects of all sizes, including those with terabytes of content and hundreds of thousands of hits per second.

The software is highly customizable, with more than 700 configuration settings and more than 1,800 extensions available to add or alter features. More than 600 automated and semi-automated bots and other tools have been developed to help edit MediaWiki sites. This free and open-source software is distributed under the terms of the GNU General Public License version 2 or any later version; documentation is released under the Creative Commons BY-SA 3.0 license and partly in the public domain. MediaWiki development has generally favored the use of open-source media formats.
