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.; Nuclino there is no publishing layer, so a public help centre or versioned product documentation cannot live here and has to be maintained in a second tool.
  • They diverge on capability: Antora covers Multi-repository sourcing, Nuclino covers Item graph.
  • Prices and features above were last checked on 31 August 2026.

  • Organisations that must keep internal knowledge hosted inside the European Unionnot Antora
  • Replacing scattered shared documents where search, not layout, is the actual problemnot 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.

Nuclino

  • There is no publishing layer, so a public help centre or versioned product documentation cannot live here and has to be maintained in a second tool.
  • The free plan is capped at roughly fifty items, which a real team passes within weeks, making it a trial rather than a usable tier.
  • Per user pricing means occasional readers who open a document twice a month cost the same as the writers who maintain it.
  • The editor is intentionally limited, with no databases, relations or page-level templates, so structured content such as a request register needs a different product.
  • Export options are limited to Markdown and PDF per item, so moving a large workspace elsewhere is a bulk conversion job rather than a supported migration.

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.

Nuclino: Can Nuclino publish a public documentation site?

No. Individual items can be shared by link, but there is no branded, versioned public site.

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.

Nuclino: Where is the data stored?

In the European Union, by a company registered in Germany, which is usually the reason procurement shortlists it.

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.

Nuclino: Does it handle translated content?

No. There is no locale model, so translations would be separate items kept in sync by hand.

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.
