Mixos Mold vs Re:Form

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.

Re:Form is a browser-based 3D sculpting studio that uses WebGPU, with macOS also listed as a platform. It offers 34 brushes and tools, including blockout, GPU subdivision, layers, symmetry, masking, vertex paint, renders, and turntables, plus pen and touch support. It runs in desktop Chrome, Edge, Firefox, and Safari 26 when WebGPU is available; there is no download or installation, and updates arrive with the web page. Projects autosave ten dated browser snapshots, while saved projects retain layers, paint, reference images, and viewport settings with the account. OBJ import and export are available on every plan; Pro adds STL, GLB, and FBX. Free supports renders up to 2048 pixels and five share links at a time. Pro adds 4096-pixel and 8K rendering, unlimited links with a public 3D viewer, and a commercial license. Free is limited to personal, non-commercial use. The product is v0.8.6 Alpha. Free is free; Pro is $9.99 a month, billed monthly.
