BookStack

BookStack at a glance

BookStack is a popular open-source, self-hosted platform for organizing documentation and knowledge in a simple books-and-pages structure. BookStack ships regular releases plus security fixes; as a web application holding organizational knowledge and user accounts, hardening and timely updates matter.

For admins updates run through the documented procedure (git or manual) and include database migrations — back up the database and uploads first, and keep the underlying PHP and database supported. Keep BookStack off the open internet behind authentication and TLS, ideally with SSO and two-factor, since documentation often contains sensitive internal detail. After upgrading, verify login, content and any integrations. Its simplicity keeps maintenance light, but it is still a web app that needs patching. The connected authentication (LDAP, SAML, social) should be checked across updates. Track the version and its releases; patchletter surfaces new BookStack versions so security fixes aren't missed.
