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.; GitBook hosted, so you do not own the rendering pipeline and are subject to platform changes
- They diverge on capability: Antora covers Multi-repository sourcing, GitBook covers Two-way Git sync.

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.
GitBook
- Hosted, so you do not own the rendering pipeline and are subject to platform changes
- Git sync is powerful but conflicts between browser and repository edits are confusing to resolve
- Pricing scales per user, which gets expensive where many people contribute occasionally
- Less customisable than a static site generator you control end to end

Questions people ask
- Is Antora or GitBook better?
- Neither clearly leads. Antora starts at Free and GitBook at Free, and user ratings are close enough to be indistinguishable. Choose on capability and platform support.
- Which is cheaper, Antora or GitBook?
- Antora starts at Free and GitBook at Free.
- Does Antora or GitBook run on more platforms?
- Antora runs on Self-hosted, Static hosting, CI pipelines. GitBook runs on Web, Cloud.
- Can I use Antora for free?
- Both have a free tier, so you can try either at no cost before committing.
- What is Antora best used for?
- Antora is most often used for publishing one documentation site from several product repositories owned by different teams, maintaining documentation for three or more supported releases without copying directories, enterprise documentation teams that already write in asciidoc and need version-aware cross-references, keeping documentation in the same repository and pull request as the code change it describes. Of those, publishing one documentation site from several product repositories owned by different teams and maintaining documentation for three or more supported releases without copying directories are not what GitBook is typically brought in for.
- What can Antora do that GitBook cannot?

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.
GitBook: Is GitBook free?
There is a free tier for public documentation, with paid team plans above it. Check current rates with the vendor.
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.
GitBook: How does Git sync work?
Changes made in the browser commit to the connected repository, and commits to the repository appear in GitBook, so both editing routes stay in step.
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.
GitBook: GitBook or Docusaurus?
GitBook is hosted and lets non-technical people write directly. Docusaurus is free and fully controllable but assumes contributors work in a repository.
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.
