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
