The short version
- Each has a real cost: BookStack there is no vendor-hosted option at all, so you own the server, TLS certificates, database backups and upgrades, or you pay a third-party host that has no support relationship with the project and no ability to fix a bug.; MkDocs no built-in versioning, which Docusaurus provides and documentation teams eventually need
- They diverge on capability: BookStack covers Shelves, books, chapters, pages, MkDocs covers Plain Markdown.

Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
BookStack
- There is no vendor-hosted option at all, so you own the server, TLS certificates, database backups and upgrades, or you pay a third-party host that has no support relationship with the project and no ability to fix a bug.
- The shelf, book, chapter, page hierarchy is fixed at four levels and cannot be reshaped, so migrating a deeply nested Confluence or MediaWiki space means flattening content by hand and losing the original structure.
- It requires PHP and MySQL or MariaDB, which is a stack many engineering teams no longer run, so adopting it usually means introducing a database and runtime nobody else in the organisation maintains.
- Development is concentrated on a single maintainer, which makes the bus factor a legitimate procurement question for anything the organisation intends to depend on for a decade.
- Content lives in the database rather than in files under version control, so there is no docs-as-code workflow, no review by pull request and no branch per release.
- Export is per page, chapter or book, so moving a large instance to another platform means writing a script against the REST API rather than copying a directory of Markdown.
MkDocs
- No built-in versioning, which Docusaurus provides and documentation teams eventually need
- Extending past the theme means writing Python plugins
- Markdown only, so embedding interactive components is not the model

Answered from the vendors’ own pages
BookStack: Is there a paid or hosted version?
No. BookStack is MIT-licensed with no commercial edition and no official hosted service. Third-party hosts exist but are unaffiliated with the project.
MkDocs: Is MkDocs free?
Yes, open source under the BSD licence. The Material theme has a free version and a paid Insiders edition.
BookStack: Can I nest pages more deeply?
No. Four levels is the design, not a limitation waiting to be fixed, and content that needs deeper nesting has to be restructured.
MkDocs: MkDocs or Docusaurus?
MkDocs is simpler and faster to adopt, especially for Python teams. Docusaurus offers versioning, internationalisation and React components, which matter once documentation grows.
BookStack: Does it support single sign-on?
Yes, through LDAP, SAML2 or OpenID Connect, with group to role mapping, and none of it is gated behind a paid tier because there is no paid tier.
MkDocs: Does MkDocs support versioned docs?
Not natively. Plugins such as mike add it, where Docusaurus includes versioning in core.
BookStack: How hard is it to migrate content in?
Straightforward for flat content through the REST API, awkward for deeply nested wikis, because the structure has to be collapsed to fit.
