Wikimedia is a global movement with a mission to bring free knowledge to the world.
We run the free encyclopedia Wikipedia, the multi-lingual structured database Wikidata, the media repository Wikimedia Commons, and other free knowledge projects. We keep the Wikimedia sites fast, reliable, and available to all. Our sites run on our own servers in five data centers across the world.
We build and use Free and Open software to make it easy to read, edit, and share from the Wikimedia sites. Our technology empowers diverse users and communities around the world to contribute and access free knowledge.
Our vibrant free and open-source community of staff and volunteers contributes to the core software MediaWiki, supports curation workflows through tools that enhance the user experience, innovates on new forms of content creation and consumption, and interacts with our data and APIs to visualize or analyze data.
