For teams maintaining shared documentation or reference material, wiki software offers a way to organize information into pages. Compare page permissions and version history for controls and change tracking, and consider page limits as your content grows. API access, custom domains, and SSO support provide further points of comparison for integration and administration; self-hosting is another option to weigh. The ranking opens with Confluence, BlueSpice, and Outline, followed by BookStack and XWiki. Check free-plan availability and paid-from pricing against the capabilities your team needs, including the page capacity and access controls that matter to your setup.
32 wiki software ranked on what their makers publish — plans and prices, free tiers, platforms and the facts on their own pages.
