Unity Editor
Unity Editor (Unity.exe) is the central IDE for building Unity projects. It hosts the scripting runtime, scene graph, editor tools, and live preview, orchestrating script compilation, asset processing, and play mode. The Editor manages project data, editor extensions, and build targets.
