The short version

  • Only Antora has a free tier, so it costs nothing to try first.
  • 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.; Redocly only as useful as your commitment to OpenAPI; teams without a maintained spec get little from it
  • They diverge on capability: Antora covers Multi-repository sourcing, Redocly covers OpenAPI reference docs.
  • Prices and features above were last checked on 31 August 2026.

  • Developer portals combining guides with generated referencenot 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.

Redocly

  • Only as useful as your commitment to OpenAPI; teams without a maintained spec get little from it
  • The portal and governance features are paid, while the open-source renderer covers only reference rendering
  • Linting rules are another thing to configure and argue about before value appears
  • Narrower than a general documentation platform, by design

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.

Redocly: Is Redocly free?

The Redoc renderer and CLI are open source and free. The developer portal and governance features are paid, with pricing published on the vendor 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.

Redocly: What does the linter do?

It enforces rules on the OpenAPI spec itself in CI — missing descriptions, naming, examples — so a poor spec fails the build rather than becoming poor documentation.

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.

Redocly: Do I need OpenAPI to use it?

Effectively yes. Without a maintained specification there is little for it to work with.

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.
