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.; Read the Docs build configuration is finicky, and build failures on dependency changes are a common frustration
- They diverge on capability: BookStack covers Shelves, books, chapters, pages, Read the Docs covers Build on commit.

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.
Read the Docs
- Build configuration is finicky, and build failures on dependency changes are a common frustration
- Default themes are recognisable and dated, so sites look alike unless customised
- Private documentation requires a paid business plan
- Build times on large projects are slow enough to interrupt a review cycle

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.
Read the Docs: Is Read the Docs free?
Free for open-source public projects. Private documentation requires a paid business plan.
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.
Read the Docs: What does it build from?
Most commonly Sphinx or MkDocs sources kept in your repository.
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.
Read the Docs: How does versioning work?
It maps branches and tags to documentation versions, so several releases are served side by side without manual work.
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.
