Best for
Git-backed wikis where Ops and Devs already version their docs.
Wiki.js strengths
- Storage backends include Git, S3, local disk and cloud providers.
- Multiple authentication sources out of the box.
- Polished editor with markdown, WYSIWYG and code modes.
Wiki.js weaknesses
- v3 rewrite slowed 2.x feature additions.
- AGPL-3.0 may block some commercial vendors.
- Node.js + Postgres requires more ops than PHP stacks.
What's the catch with Confluence?
- Search quality degrades as workspaces grow.
- Permissions model is hard to reason about.
- Tightly coupled to the Atlassian suite lifecycle.
