XWiki

XWiki Platform offers runtime services for applications built on top of it, making it a generic wiki platform in the literal sense. The distinction matters: rather than a place to write pages, it is a substrate other tools are written against, which is why a wiki, a knowledge base, and a small internal application can all be the same deployment.

The platform is a large Java build released in step with XWiki Commons and XWiki Rendering, three projects sharing a version number and the same software forge. Its core splits into modules that each cover a single service, so a deployment carries only what it uses.

Those modules are where the platform's capabilities live.

• Editing: a CKEditor-based WYSIWYG surface alongside real-time collaborative editing built on Netflux and Yjs.
• Structured content: App Within Minutes, classes, sheets, and LiveData tables turn pages into structured records.
• Collaboration: notifications, mentions, annotations, ratings, and likes attach to the content people work on.
• Extension management: an extension repository and a flavor system install and update components at runtime.
• Integration: a REST API, WebSocket support, office document import, and feed handling connect the wiki to a wider stack.
• Administration: permissions, cryptography, CSRF protection, a scheduler, and statistics cover the operational side.

Distributions are published as a WAR for an existing servlet container, as a standalone Jetty and HSQLDB bundle for a quick start, and as a Debian package. The code is LGPL-2.1, continuous integration builds every commit, and issues are tracked in the project's own JIRA rather than on GitHub.
