BookStack works well if you already have someone who can run a small server.
You get a clean wiki with books, chapters, and pages plus full search and SSO logins (OIDC, SAML, LDAP), with no per-user fees ever. If you don't have technical staff to install and maintain it, a hosted tool will save you the setup work.
BookStack needs a developer to set up and use, so we don't give it an owner rating. Here is how each factor looks for a small team that has a developer.
- SMB Fit
Built for teams that can host it themselves; the software is free and open source with roles and permissions, SSO and diagrams built in.bookstackapp.com (source, opens in a new tab)
