Sphinx is described as 'Tool that makes it easy to create intelligent and beautiful documentation, written by Georg Brandl and licensed under the BSD license' and is a documentation generator in the development category. There are more than 50 alternatives to Sphinx for a variety of platforms, including Linux, Self-Hosted, Mac, Windows and Web-based apps. The best Sphinx alternative is GitBook, which is free. Other great apps like Sphinx are Wiki.js, MkDocs, Quartz – Static Site Generator and Doxygen.


docsify generates your documentation website on the fly. Unlike GitBook, it does not generate static html files. Instead, it smartly loads and parses your Markdown files and displays them as website. All you need to do is create an index.


Read the Docs hosts documentation for the open source community. It supports Sphinx docs written with reStructuredText, and can pull from your Subversion, Bazaar, Git, and Mercurial repositories. The code is open source, and available on github.




Presidium is a software documentation management system for agile teams, and their users, made from commonly used open source components.
Open-source headless CMS ideal for programming blogs, offering a modern WYSIWYG editor, Markdown, code formatting, real-time collaboration, Kanban dashboard, and versatile API for content delivery.




DocFX generates Documentation directly from source code (.NET, RESTful API, JavaScript, Java, etc...) and Markdown files.
Write your documentation in Markdown and create a professional static site in minutes – searchable, customizable, in 60+ languages, for all devices.

Doclets.io is the missing hosted and automated API-Doc generation service for Javascript. By simplifying API-Doc setup it enables you to actually focus on writing documentation!


Documize creates the Enterprise Knowledge Backbone by unifying docs, wiki, reporting and dashboards — composition + coordination + discovery + distribution + workflows = faster business outcomes



A static site generator for creating documentation sites from AsciiDoc content aggregated from multiple repositories. Made by the creators of Asciidoctor.

ReadTheDocs (RTD) is a Sphinx-doc hosting site, not a docsite generator itself and therefore not an alternative. RTD is a great add-on to Sphinx use.
