Mediawiki

MediaWiki provides a web‑based platform for collaborative editing and documentation, allowing users to create, organize, and share knowledge in a structured wiki format. It supports multilingual content, page versioning, and fine‑grained access controls, making it suitable for public encyclopedias, internal knowledge bases, and community sites. The software can be installed on a self‑hosted server, offering a free, open‑source solution without subscription fees.

The system is extensible through a wide range of extensions that add functionality such as visual editing, semantic data handling, and custom authentication methods. Documentation and developer resources are available to help administrators configure the platform, troubleshoot issues, and contribute code or translations. A vibrant community maintains regular maintenance and security releases, ensuring stability and ongoing improvements.

MediaWiki is licensed under GPL‑2.0 and is used by thousands of organizations and tens of thousands of websites, including the Wikipedia family of projects. Its design emphasizes reliability, customizability, and collaborative knowledge management for both large‑scale public portals and smaller private deployments.
