Overview
Wiki.js is a modern open-source wiki engine running on Node.js with Markdown and visual editors, full-text search, and a flexible page hierarchy. It supports many authentication providers, storage backends, and Git-based syncing. It is a flexible Confluence/Notion alternative for documentation-heavy teams.
Key features
- Markdown and WYSIWYG visual editors
- Full-text search across pages
- Flexible page hierarchy and navigation
- Many authentication providers supported
- Pluggable storage backends with Git-based syncing
Our take
Wiki.js is a polished Node.js wiki engine that earns its popularity through breadth: dual Markdown/visual editors, full-text search, a sensible page hierarchy, and an unusually long list of auth providers and storage backends. The Git-based syncing is a standout, letting your content live in a repo rather than locked inside the app, which is reassuring for long-term ownership. The main caveat is that it covers a lot of surface area, so initial configuration of auth, storage, and search can take some patience, and a long-running 3.0 rewrite has historically left some users unsure which version to commit to. If you accept that setup tax, it is a capable, flexible documentation home for a team that has outgrown scattered Markdown files.
Ideal for: Documentation-heavy teams wanting a self-hosted Confluence or Notion replacement with Git-backed content portability.
Where it falls short of Confluence
- No real-time collaborative editing.
- No database/table views or relational content.
- The long-awaited 3.x rewrite has been slow and partly unstable.
- Requires a separate database (Postgres/MySQL) to be configured.
We list the gaps honestly so you can decide if the trade-off is worth owning your data.
