Confluence alternatives compared
Outline and Wiki.js tie at 98/100. Outline also has the largest following, at 41k stars.
The most recent release is Wiki.js 3.0.0-beta.705, published 4 days ago. None of the measured options scores under 40. By stack, Nodejs (3), PHP (3) and Java (1) are the most common. BookStack is permissively licensed; Wiki.js, docmost Community Edition, XWiki and 2 more are copyleft. Outline is source-available rather than open source, which limits commercial reuse. Mediawiki is not hosted on a forge Repoly can read, so it has no measured score yet.
