Godot GDExtension (C++ Bindings)
GDExtension is Godot 4's mechanism for binding native C++ (or any language with a C ABI) into the engine without recompiling Godot itself. GDExtension libraries register their own classes against the engine API and behave like first-class engine classes. The official godot-cpp binding repo provides the C++ API headers.
Godot GDExtension (C++ Bindings) is one of 5 APIs that Godot Engine publishes on the APIs.io network.
Tagged areas include C++, GDExtension, Native, and SDK. The published artifact set on APIs.io includes API documentation and a GitHub repository.
