This organization hosts Rosetta — a C++26 reflection-based, multi-language binding generator — together with the libraries that use it to expose existing C++ codebases to other languages without modifying a single line of their source.
The idea is always the same: point Rosetta at unmodified C++ headers via a small manifest.json, run one tool, and get a ready-to-build binding project per target language (pybind11 / nanobind, N-API, Emscripten/embind, Qt, QML, REST, OpenAPI, Julia, TypeScript, C#, Java, JSON, Markdown, HTML, ParaView, …).
C++26 reflection (P2996) does the discovery; the consumer libraries in this org are concrete applications of that engine to real-world codebases.
