BookStack

BookStack is an excellent choice when you want a documentation tool that people actually enjoy using. Its book → chapter → page structure matches how most teams naturally think about organizing information, so onboarding is almost frictionless. Because it’s self-hosted, you retain full control over your data, access, and infrastructure, which is critical for teams with compliance, privacy, or security requirements.

The WYSIWYG editor lowers the barrier to contribution: non-technical users can create and edit content without learning markdown or complex formatting rules, which leads to broader adoption across the organization. Combined with its intuitive navigation and clear hierarchy, BookStack works especially well as a wiki replacement where previous tools have failed due to complexity or poor user experience. If your goal is a structured yet simple knowledge base that your team will actually keep up to date, BookStack is a strong, practical recommendation.
