The short version
- Each has a real cost: Antora content must be AsciiDoc, so an existing markdown documentation set has to be converted before you can evaluate the tool properly.; 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.
- They diverge on capability: Antora covers Multi-repository sourcing, BookStack covers Shelves, books, chapters, pages.

- Publishing customer-facing manuals from the same instance as internal documentation using per-book permissionsnot Antora
Where each one falls short
Documented limitations, not opinions. Every one is a constraint you would hit in normal use.
Antora
- Content must be AsciiDoc, so an existing markdown documentation set has to be converted before you can evaluate the tool properly.
- The component, version and module model must be understood before anything builds, and the first working site typically takes days rather than the afternoon a markdown generator needs.
- Theming means building a separate UI bundle with Handlebars templates and its own pipeline, which is a front-end project most documentation teams are not staffed for.
- There is no search included, so every deployment adds either a Lunr extension with its own index size limits or a paid hosted search service.
- Builds fetch from every configured repository, so large multi-component sites become slow and depend on git availability during every documentation build.
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.

Answered from the vendors’ own pages
Antora: Can I use markdown with Antora?
Not as the primary format. Antora is an AsciiDoc pipeline, and treating markdown as a first-class input means a different tool.
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.
Antora: Is it worth it for a single product with one version?
Usually not. The model pays off when you have several repositories or several supported versions; below that a simpler generator will do the same job with far less setup.
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.
Antora: How does versioning actually work?
Each branch or tag of a source repository becomes a version of that component. You publish a new version by branching, not by copying a directory.
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.
Antora: Who maintains it?
OpenDevise, the group behind Asciidoctor, under the Mozilla Public Licence. Paid consulting and custom UI work are available from them separately.
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.
