SculptGL
What it is
SculptGL is a free digital sculpting app for the web, with Windows and Chrome extension versions also available. Its tools include Brush, Inflate, Smooth, Twist, and Drag, with undo and redo for editing. Vertex painting supports color, roughness, and metalness, and users can apply alpha textures with each tool. Multiresolution sculpting uses Catmull-Clark and Loop subdivision while preserving changes across subdivision levels. For mesh work, voxel remeshing uses SurfaceNets to create quad-only meshes, while dynamic topology performs local subdivision and decimation in real time using triangles. Both methods delete UVs. SculptGL imports and exports OBJ, PLY, and STL files and can read vertex color. The maker offers a standalone version described as identical to the web app, with 32-bit and 64-bit Windows downloads. The maker’s repository says the project is no longer maintained apart from small or minor fixes and was archived on January 17, 2026.
