Wiki.js vs XWiki
Both are alternatives to Confluence. Here's how they stack up — verified facts, no spin.
Also searched as XWiki vs Wiki.js — same comparison, one verdict.
Wiki.js and XWiki are closely matched on ownership (92 vs 91) — this one comes down to pricing and to which trade-offs below you can live with.
Wiki.js
Every editor, every auth provider, every storage backend.
Wiki.js is the flexible one: Markdown, WYSIWYG, HTML and AsciiDoc editors, more than fifty authentication providers, and content that can sync to Git so your wiki has real version history in a repository you control. AGPL-3.0, around 29k stars. That Git sync is the feature worth noticing — it makes documentation reviewable in pull requests, which is how engineering teams already work. The trade is configuration: it does a great deal, and it asks you to decide about most of it.
XWiki
The heavyweight — a wiki you can program like an application platform.
XWiki has been running enterprise documentation for two decades and is less a wiki than a platform you write applications on top of: structured data, scripting, forms and workflow all live inside the wiki itself. LGPL-2.1, Java, with a large extension marketplace. It is the only option here that genuinely replaces Confluence Data Center feature for feature, including the parts organisations use for regulated processes. It is also the heaviest, and it looks its age next to Docmost.
Side by side

Weighing both against staying on Confluence? Is Confluence free? What it actually costs →
Wiki.js
Strengths
- +Git storage backend gives real version control over documentation
- +Over fifty auth providers — SSO into almost anything
- +Multiple editors, so writers are not forced into one style
- +Mature, with years of production use
Trade-offs
- −More configuration than BookStack before it feels finished
- −Node and a database to operate
- −Version 3 has been a long time coming
- −Search is adequate rather than excellent
XWiki
Strengths
- +The only true Confluence Data Center replacement, feature for feature
- +Structured data and scripting — build applications inside the wiki
- +Two decades of enterprise deployment behind it
- +LGPL with commercial support available
Trade-offs
- −Heaviest option here — a Java application to operate
- −Interface is dated next to the newer tools
- −Steep learning curve for the platform features
- −Overkill if you just want to write pages
Which one fits you
The trade-offs above, turned into a decision. Find the line that describes your team.
Choose Wiki.js
if a lower exit cost matters more to you than any single feature, and git storage backend gives real version control over documentation.
Choose XWiki
if the only true Confluence Data Center replacement, feature for feature.
Neither, yet
if both carry a real cost you should weigh first — more configuration than BookStack before it feels finished, and heaviest option here — a Java application to operate. If either of those is a dealbreaker for your team, the shortlist is wrong rather than the choice.
Wiki.js vs XWiki — common questions
Is Wiki.js a better fit than XWiki for wikis & internal docs?
It depends on what you are optimising for, and the honest split is this: Wiki.js scores 92 to XWiki's 91 on data ownership and exit cost, so it is the safer choice if you care about being able to leave. XWiki earns its place on a different axis — the only true Confluence Data Center replacement, feature for feature. Neither is a wrong answer for every team; the table above is the actual comparison.
What happens if we want to switch later?
Wiki.js keeps its data local or in open formats, so leaving is an export rather than a negotiation. XWiki is still self-hostable, so the files stay on your server either way — but it is not local-first by design, so check what its export produces before you rely on it.
Can I self-host Wiki.js or XWiki?
Both can be self-hosted. The difference is what it costs you in time rather than whether it is possible — see the setup and maintenance rows above.
Are Wiki.js and XWiki both alternatives to Confluence?
Yes — both appear in our Confluence comparison, which is why they are worth putting side by side. People usually arrive here already having decided to move off Confluence and now choosing between the two replacements, which is a narrower and much easier question.
