Wiki.js
Modern self-hosted wiki with a first-class markdown editor.
Wiki.js is a modern, open-source wiki engine that runs on Node.js. Its primary editing experience is a markdown editor with live preview, alongside visual and other editors, with pages stored optionally as markdown files synced to Git.
Granular permissions, search, authentication providers, and theming make it a common pick for team knowledge bases that want wiki structure with markdown ergonomics.
