Best Wiki Software 2026

Wiki software provides collaborative knowledge management platforms where teams create, organize, and maintain shared documentation and institutional knowledge. Page creation and editing uses rich text editors or markdown for writing and formatting documentation with version history tracking all changes. Hierarchical organization structures content through nested pages, spaces, and categories creating navigable knowledge architectures. Search functionality indexes all content for finding specific information quickly across large knowledge bases. Collaborative editing allows multiple contributors to work on documentation with change tracking, comments, and approval workflows. Templates standardize common document types like meeting notes, project briefs, technical documentation, and onboarding guides. Permission management controls who can view, edit, and publish content at the page, space, or organization level. Integration with development tools, project management, and communication platforms embeds knowledge into where work happens.
