## What it is
Doxygen is the de facto standard open-source tool for generating documentation from annotated source code, with primary support for C++ and additional support for C, Python, Java, PHP, C#, Objective-C, Fortran, VHDL, and more. It parses source comments and code structure to produce HTML, LaTeX/PDF, RTF, XML, and man-page output, including dependency graphs and inheritance diagrams.

## Use cases
- generate api documentation from c++ source comments
- produce html and pdf reference manuals from code
- extract class structure from undocumented codebases
- generate inheritance and collaboration diagrams
- document a multi-language codebase consistently
- create offline documentation for a large c project

## When to choose
- you maintain C, C++, or other compiled-language code needing API docs
- you want documentation generated directly from source comments
- you need multiple output formats like HTML, PDF, and man pages
- you want automatic diagrams of code structure

## When to avoid
- you need docs for JavaScript/TypeScript web projects with modern tooling ecosystems
- you want a docs-as-code static site with custom theming beyond Doxygen's customization
- your project is documentation-only with no source code to parse

## Facets
- artifact type: cli-tool
- maturity: stable
- function: documentation, parser, static-site-generator
- domain: documentation, developer-tools, parsers
- platform: windows, cross-platform, cli
- tags: api-documentation, code-documentation, doxygen, diagrams, cross-referencing, c-plus-plus, linux, macos
