Best CMS for Wikis
BeginnerQuick Answer
TL;DR
For internal team wikis, Notion, Confluence, and Outline are the most popular choices — they're purpose-built for collaborative documentation with version history, linking, and search. For public-facing wikis, MediaWiki (the software behind Wikipedia) remains the standard. A general-purpose CMS can work for wiki-like content, but dedicated wiki tools handle collaborative editing, page linking, and version history far better out of the box.
Key Takeaways
- Internal wikis: Notion, Confluence, Outline, and Coda are purpose-built for team knowledge management with collaborative editing.
- Public wikis: MediaWiki is the proven open-source standard; DokuWiki is a simpler alternative.
- General-purpose CMS platforms (WordPress, Contentful) can host wiki-style content but lack native wiki features like bidirectional page linking and edit history per contributor.
- The key wiki features to look for: version history, page linking/backlinks, collaborative editing, search, and access control.
- For developer documentation that functions like a wiki, GitBook and Readme.io are strong alternatives.
