MediaWiki

MediaWiki is a free, open-source software platform used to create and manage collaborative websites, most famously Wikipedia. It allows multiple users to easily add, edit, and organize content on web pages through a simple interface. MediaWiki's robust version control tracks changes, enabling users to see history and revert edits if needed. It supports features like categories, links, and multimedia. Designed for scalability, it can handle large amounts of data and numerous contributors, making it ideal for encyclopedias, knowledge bases, and collaborative projects that require transparent, collaborative content management.
