What Antora is

Antora is an open-source documentation site generator for technical writers who work in AsciiDoc. It gathers content from one or more local or remote Git repositories, including private repositories, and uses repository branches to build versioned documentation collections. A playbook tells Antora which documentation to assemble, where to locate it, and which UI to apply; branches can be left out of the published collection.

Its AsciiDoc support covers tables, media, cross references, metadata, navigation, and syntax-highlighted source code. Custom extensions and generator pipelines can extend its open architecture. Generated sites can go to local or remote destinations, with support for different publishing environments. Antora creates static sites; its documentation says this avoids the need to patch a deployed CMS application. It runs on Node.js and is verified on Linux, macOS, and Windows, and a project Docker image can run with Docker or Podman. Antora is free under the Mozilla Public License 2.0. OpenDevise offers optional Pro Support for $14,000 a year and Premier Support for $30,000 a year. The listed capabilities also include documentation versioning, documentation analytics, and reader analytics.
