BookStack

BookStack is an open-source wiki and documentation platform, and a self-hosted alternative to Confluence. Content is organized into a deliberate three-level hierarchy — shelves hold books, books hold chapters and pages — which keeps large knowledge bases navigable. It ships WYSIWYG and Markdown editors, a diagrams.net integration, full-text search, page revisions, and SSO via SAML2, OIDC, and LDAP.
