Scope: A small sculpting application in JavaScript and WebGL, used for organic shapes. It needs no registration and runs in the browser.	Scope: A professional digital sculpting tool with over 200 brushes, remeshing, ZModeler, Live Boolean, PolyPaint, UV Master and Redshift rendering. Much deeper than SculptGL.	Scope: Described as a 3D creation suite with a Python API. The project page does not list sculpting functions, so scope is broader than a sculpting application.	Scope: A free sculpting tool from Pixologic, now treated as legacy software.
Status and maintenance: The GitHub repository is archived. The author states that SculptGL is no longer maintained apart from small fixes. Expect stability, not new features.
