The stock interface design has a modern feel and is simple for new users to use.
Pro Free and open source
Released under the MIT license.

Pro Multilingual
Over 9 different languages are built in to BookStack which can be set at a per-profile level.
Pro Feature rich and stable
Markdown editing, syntax highlighting, WYSIWYG, keyboard shortcuts, versioning, SSO, LDAP, different roles, performant and fast developer response.

Cons
Con External program must be used for editing
A separate program must be used to make changes to documents as MDwiki lacks a built-in editor.
Con Requires additional permissions in Google Chrome
Supposedly, you can get it to work in Google Chrome by modifying JavaScript permissions, but these same changes may decrease security.
Con Limited customisability
Customisation options are limited with only the main theme color, logo and name being customisable.
Con No support for readable markup languages
The content entered through the WYSIWIG editor is stored as HTML. The HTML can be edited directly, but no other markup language is parsed. Speak ReST, Markdown, etc.
Con Limited to 2 levels of content
Bookstack implements a "Book / Chapter / Page" system which works fine, but lacks flexibility when you need to have more levels of imbrication.
Con Complicated installation
The current installation process involves many steps and may be a lot to take in for people not familiar with setting up Laravel applications.
