XWiki
Enterprise wiki platform with structured data, scripting, and extensibility
Overview
XWiki is a mature, Java-based enterprise wiki that goes beyond simple page editing — pages can contain structured data, queries, and Groovy/Velocity scripts making it a hybrid wiki-application platform. It supports multi-tenant installations, granular access control, and a rich extension marketplace. Deployed via WAR file on Tomcat or as a Docker image.
Where it falls short of Confluence
- JVM memory footprint is heavy; needs 1-2 GB RAM minimum for comfortable operation
- UI feels dated compared to modern Confluence or Notion interfaces
- Initial setup and Tomcat configuration have a steep learning curve for non-Java admins
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
