Documentation Publishing Tools
Documentation publishing tools turn plain-text source files into a documentation website, PDF, or API reference that readers can browse. They range from static site generators like Sphinx, MkDocs, and Docusaurus to hosted platforms like Read the Docs and GitBook and generators built specifically for API references. The tool a team picks shapes how it writes, versions, searches, and ships documentation.

Intro
Documentation Publishing Tools
A documentation publishing tool converts plain-text source into a reader-facing artifact: an HTML site, a PDF, an ePub, or an interactive API reference. It is the layer between what a writer edits and what a reader sees.
These tools fall into three overlapping groups. Static site generators, such as Sphinx, MkDocs, Docusaurus, Hugo, VitePress, Jekyll, and Zola, read source files and configuration and produce prebuilt HTML you can host anywhere. Hosted platforms, such as Read the Docs and GitBook, add build automation, versioning, and hosting around a generator or their own editor. Specialized generators, such as Antora, the DITA Open Toolkit, Doxygen, Swagger UI, and Redoc, target one publishing problem — multi-repository aggregation, structured single-sourcing, source-code comments, or OpenAPI descriptions — rather than general-purpose sites.
The build pipeline
Every generator in this category follows the same shape:
Source files + configuration
|
v
Parser (Markdown, reStructuredText, AsciiDoc, MDX, DITA XML)
|
v
Generator / build process
|
v
Theme + templates -> Rendered pages
|
v
Static output (HTML, PDF, ePub) -> Hosting
