Best Wiki Software in 2026

Wiki software gives you a shared space to create, organize, and maintain reference pages for a team or community. Compare page permissions and version history to judge how access and edits are handled, and consider page limits as your collection grows. API access, custom domains, and SSO support add useful points of comparison for integration and administration; self-hosting may matter if you want to run the software on your own infrastructure. Confluence, MediaWiki, and MoinMoin are among the entries to explore. Check free-plan availability and paid-from pricing alongside the features that suit your needs.
