Antora
Antora is a documentation site generator for technical writers working in AsciiDoc.
What Antora is
Antora is a documentation site generator for technical writers working in AsciiDoc. It can assemble content from local or remote Git repositories, including private repositories, and use repository branches to create versioned documentation collections. A playbook defines which documentation to collect, where it is located, and which user interface to apply; branches can be left out of publication.
Antora includes AsciiDoc support for tables, media, cross references, metadata, navigation, and syntax-highlighted source code. Its architecture supports custom extensions and generator pipelines. Generated sites can be published to local or remote destinations and adapted to different publishing environments. Because Antora creates static sites, its documentation notes that there is no deployed CMS application to patch. It runs on Node.js and is verified on Linux, macOS, and Windows, with a Docker image for Docker or Podman. Antora is open source under the Mozilla Public License 2.0 and is free. OpenDevise offers optional Pro Support for $14,000 a year and Premier Support for $30,000 a year.
