What it is
SculptGL is a digital sculpting app that runs in a browser using WebGL and JavaScript. Its tools include Brush, Inflate, Smooth, Twist, and Drag, with undo and redo for edits. Vertex painting supports color, roughness, and metalness, and tools can use alpha textures. Multiresolution sculpting uses Catmull-Clark and Loop subdivision and retains changes when moving between levels. 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 reads vertex color. A standalone version is described as identical to the web app, with 32-bit and 64-bit Windows downloads; a Chrome extension is also available. The app is free and open source, with no paid plan or usage limits stated on the maker’s pages. Its repository says maintenance is limited to small fixes and was archived on January 17, 2026.
