We keep Wikimedia projects fast, reliable, and available to all.
From hosting Wikipedia to creating edit-checking artificial intelligence (AI), we design and build the open-source technology that powers Wikimedia projects. Community volunteers and Foundation technologists collaborate on MediaWiki, the platform that makes sharing free knowledge possible.
Hosting the world’s knowledge
Wikipedia is the fifth most-visited website in the world, with more than 6,000 visits every second. Our infrastructure keeps it online. Over the last year, we delivered an uptime of 99.97% (according to independent monitoring) across all project sites.

More than half of Wikimedia’s visitors connect from mobile devices. But high mobile data costs across Africa, Latin America, and Asia can make accessing Wikipedia expensive. That is why we redesigned our apps and sites to be up to 51% less data intensive.
Assisting human collaboration with machine learning
Anyone can edit Wikipedia, and it can be challenging to maintain quality control. That is why we made ORES, an artificial intelligence service that automatically identifies potentially problematic content as soon as it appears, advising editors if changes are needed.
NASA’s internal wiki for collaboration and documentation is built on MediaWiki, just like Wikipedia. We create MediaWiki—open-source wiki software that is free and available for anyone.
