XWiki vs Docmost
Both are alternatives to Confluence. Here's how they stack up — verified facts, no spin.
Also searched as Docmost vs XWiki — same comparison, one verdict.
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.
Docmost
The modern one — real-time collaborative editing, Notion-like feel.
Docmost is the newest serious entrant and feels it: block-based editor, real-time collaboration, nested pages, comments and diagrams, with the polish people expect after using Notion. AGPL-3.0, around 21k stars and moving quickly. It is the closest thing here to the editing experience that makes people reluctant to leave Confluence. The caveat is age — it has the shortest production track record on this page, and AGPL is strong copyleft worth reading if you intend to modify it.
