In their own words
Asciidoctor
Asciidoctor is a free, open-source text processor and publishing toolchain for converting AsciiDoc files or strings into formats such as HTML5, DocBook, PDF, EPUB 3 and manual pages. Its core includes converters for HTML5, DocBook 5 and man pages; PDF and EPUB 3 conversion comes from separate gems. Documents can be processed through a command-line interface or Ruby API. Asciidoctor runs with Ruby, on the JVM through AsciidoctorJ, or in JavaScript environments through Asciidoctor.js, and supports Linux, macOS and Windows. The wider ecosystem includes Maven and Gradle plugins, browser and editor extensions, and diagram tools. Default HTML output includes a stylesheet and integrations such as Font Awesome, highlight.js, Rouge, Pygments and MathJax. It is distributed as a RubyGem, Docker image, Linux packages and macOS packages, and is licensed under MIT. Its security modes include SECURE, SAFE, SERVER and UNSAFE; safe modes do not sanitize generated output or provide a comprehensive security framework.
Natural Docs
Natural Docs is a command-line documentation generator that scans source-code comments and text files to create HTML documentation, including API references. Its syntax is designed to read like ordinary English in both source code and generated pages. The project says it comes configured for 25 programming languages and can be extended; for certain languages, it can also read Javadoc and Microsoft XML comments without rewrites. Generated pages have three panels, dynamic navigation, search and summaries that appear when readers hover over links. They can be opened from a local hard drive without installed software, and styled with custom CSS and images. Natural Docs runs on Linux, macOS and Windows. It is free and open source under AGPL version 3. The license requires source availability for modified distributions, projects incorporating its source, and services incorporating its functionality; merely documenting a project does not place that project under AGPL. Help is available through a Reddit forum, email and GitHub issues, with commercial support contracts available to businesses.
