What people use each for

The jobs each tool is most often brought in to do.

Antora

  • Publishing one documentation site from several product repositories owned by different teamsnot MadCap Flare
  • Maintaining documentation for three or more supported releases without copying directoriesnot MadCap Flare
  • Enterprise documentation teams that already write in AsciiDoc and need version-aware cross-referencesnot MadCap Flare
  • Keeping documentation in the same repository and pull request as the code change it describesnot MadCap Flare

MadCap Flare

  • A technical writing team moving off an unsupported or discontinued help authoring tool that needs single-source, multi-format publishingnot Antora
  • An enterprise documentation team needing conditional content to manage several product editions from one sourcenot Antora
  • A team wanting a familiar desktop authoring workflow rather than a browser-only or fully structured CCMS environmentnot Antora
  • A documentation team that needs reviewer seats for subject matter experts without giving them full author licences, available on the Online plansnot 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.

MadCap Flare

  • Flare is now subscription-only at $3,150 per author per year; a buyer who previously owned a perpetual licence faces an ongoing cost that did not exist under the old purchase model
  • A 12-month commitment is required on Flare Online, so a team cannot trial the cloud tier month to month before committing budget
  • Pricing above the Desktop base tier is entirely quote-based for Online plans, so team and business-tier costs are not comparable across vendors without a sales call
  • The authoring model, while less rigid than a full CCMS, still requires writers to learn topic-based structuring, conditional tags and variables, which is a real ramp for staff used to Word or a wiki
  • Storage is capped per tier with paid add-ons in 10 GB increments, so a documentation set with heavy image or video assets can incur additional cost beyond the headline price
  • Windows-only desktop authoring limits teams that standardise on macOS or Linux to the browser-based Flare Online tier, which may not have full feature parity with desktop

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.

MadCap Flare: Is there still a perpetual licence option?

No, MadCap Flare is sold on an annual subscription basis; the previous perpetual licence model is not offered on current pricing.

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.

MadCap Flare: What is the entry price?

Flare Desktop is $3,150 per author per year; Flare Online plans are quote-only.

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.

MadCap Flare: Is there a minimum commitment?

Flare Online requires a 12-month commitment; Flare Desktop is billed annually.

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.
