Technology

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 one of the top most-visited websites in the world, accessed by 1.5 billion unique devices every month. Our infrastructure keeps it online.

Making Wikipedia easier to use

Through technical and design improvements to Wikipedia’s desktop and more, we make the site easier to use and more welcoming for readers and contributors alike.

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.

Helping NASA

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.

Mentoring new developers

To help build a more diverse and inclusive technical community, the Wikimedia Foundation funds, supports, and mentors new developers and underrepresented groups in tech.

Growing a volunteer developer community

Over half of the commits made to our codebase are pushed by volunteers. We actively support a thriving volunteer technology community, with grants, events, and an open collaboration tool.

Help us unlock the world’s knowledge.

As a nonprofit, Wikipedia and our related free knowledge projects are powered primarily through donations.

Wikipedia’s value in the age of generative AI

If there was a generative artificial intelligence system that could, on its own, write all the information contained in Wikipedia, would it be the same as Wikipedia today?
