Antora

What Antora does

Antora is an open-source, modular documentation site generator developed and maintained by OpenDevise Inc., a private Colorado-based corporation founded in 2017. The product is purpose-built for DevOps-oriented technical writing teams who author content in AsciiDoc and need to aggregate, version, and publish documentation sourced from one or more Git repositories. Its core technology is a Node.js-based pipeline composed of discrete components (AsciiDoc Loader, Content Aggregator, Content Classifier, Document Converter, Navigation Builder, Page Composer, Playbook Builder, Site Generator, Site Mapper, File Publisher, and UI Loader) governed by a YAML playbook that configures content sources, versions, and UI. Antora retrieves content over any git protocol from local, remote public, or remote private repositories, supports Git-branch-based versioning, and publishes static sites to environments including GitHub Pages, GitLab Pages, and Netlify. The product suite extends to official Maven and Gradle plugins, a Docker/OCI image, a Default UI archetype theme, and a Lunr-based offline full-text search extension.

Antora's go-to-market is community-led and self-serve. The core software is distributed under the Mozilla Public License 2.0 via npm, Docker Hub, Maven Central, and the Gradle Plugin Portal, with discovery and support driven by GitLab repositories, a Zulip community chat, and the @antoraproject Twitter account. The only monetized stream is professional services from OpenDevise Inc., covering migration, custom development, DocOps, technical content consulting, and support subscriptions. No paid tiers, enterprise licensing, or SaaS product exist. The customer base is horizontal — any technical documentation team using AsciiDoc — and no customer logos or enterprise accounts are publicly disclosed. With 11-50 employees and no outside funding, Antora functions as a self-sustaining open-source project with a services overlay rather than a venture-backed software company.

It supports multi-repository content aggregation, Git-branch-based versioning, playbook-driven site configuration, multi-channel publishing, and an open architecture with a JavaScript extension API.

Product overview

Antora is a modular, open-source documentation site generator designed for DevOps-savvy technical writing teams. The product suite consists of the core Antora CLI and Site Generator (which orchestrate the entire pipeline), the Antora Default UI (the archetype theme), and the Antora Lunr Extension (for offline full-text search). Antora's modular architecture is built on individual AsciiDoc-processing components (AsciiDoc Loader, Content Aggregator, Content Classifier, Document Converter, Navigation Builder, Page Composer, Playbook Builder, Redirect Producer, Site Mapper, File Publisher, UI Loader) that can be assembled into custom pipelines or replaced. Build tool integrations include official Gradle and Maven plugins, and a Docker/OCI image is available. Antora is built and extended using Asciidoctor (the AsciiDoc processor), whose core team leads the Asciidoctor open source organization that Antora maintains a direct relationship with.
