VERDICT

Should I use XWiki?

The Advanced Open-Source Enterprise Wiki - xwiki.com

Depends. Buy if you're a mid-size or larger org with IT staff who want an open-source Confluence alternative. Skip it if you're a small team wanting a simple wiki — even Reddit users call it overkill.

Confidence

Medium. Based on 30+ public sources; several review snippets truncated, so review coverage is thin (13 G2 reviews).
