Mixos Mold vs SculptGL

Mixos Mold is browser-based 3D sculpting software for shaping organic forms with GPU sculpting and pressure-sensitive brushes. Its toolset includes subdivision, dynamic topology, masking, symmetry, stamp alphas, brush presets, and remeshing. Users can import OBJ, FBX, or GLB models, unwrap a sculpt, and send it to Mixos Paint for layered PBR texturing. Mold runs without installation in a WebGPU-capable browser; desktop browsers listed are Chrome, Edge, Firefox, Brave, and Safari 26 or later. It also runs on iPad and Android in compatible browsers, and is included in the free Mixos iOS app for iOS 26 or later. Sculpting and saving to a library are free, but exporting finished meshes as GLB, OBJ, or STL requires a paid plan or perpetual license. Pro costs $8.99/mo, Max costs $17.99/mo, and a perpetual license costs $99 once. Account-saved projects can be opened across devices after sign-in. The maker says editing runs locally in the browser, but provides no equivalent security audit or uptime guarantee.

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.
