CxxDox does not depend on Doxygen as it performs parsing using libClang (bundled in .whl for Windows and Linux). 100% doxygen compatibility was not a goal, but it has enough features to serve as the documentation engine for a large C++ library, such as KFR. An example of the generated documentation is live at https://docs.kfr.dev/_gen/

Supports: C++ and C, with all modern standards (thanks to Clang 21). Generation of symbol pages under any path prefix. Groups, global and per-type indexes. Easy links to C++ symbols in any .md page. Testable snippets.

Works best with mkdocs-material. The plugin is created and maintained by the author of KFR, a C++20 DSP library.
