ZBrush alternative
Push, pull, smooth and crease organic form with pressure-sensitive brushes, take a base mesh into millions of triangles with multiresolution subdivision, and remesh when the topology stops cooperating. It runs in a browser tab, it's free to sculpt, and the model hands straight to a PBR texture painter when you're done.
29 brushes, from Clay, Dam and Pinch to Elastic Move, Pose and Move Topological — pressure-sensitive, with alphas on nearly every brush, falloff curves, symmetry on any axis and masking. The core sculpting loop, not a toy subset of it.
Subdivide into millions of triangles to sculpt broad form low and fine detail high, stepping between levels freely. Or switch on live dynamic topology, which adds and removes triangles under the brush as you sculpt — the roles Sculptris Pro and DynaMesh play in ZBrush.
No multi-gigabyte installer, no license activation, no maintenance plan. Open a URL on Mac, Windows or Linux — or on an iPad with an Apple Pencil — and start sculpting.
ZBrush hands you a high-poly mesh and wishes you luck downstream. One click here unwraps the sculpt with fresh UVs and opens it in a layered PBR painter, in the same browser.
Why Mixos
ZBrush is the industry standard for a reason: two decades of depth, hundreds of configurable brushes, ZRemesher, ZModeler, Fibermesh, and a place in almost every film and games character pipeline. If you sculpt production characters for a living, none of that is replaceable, and this page is not going to pretend otherwise.
What Mold does is take the part most people actually use every day — direct, pressure-sensitive brush sculpting over a subdivided mesh, with masking, face sets, mirror and radial symmetry, live dynamic topology, and voxel or field-aligned quad remeshing — and run it in a browser tab. On a desktop with 8 GB or more it divides to around six million triangles, the heavy operations run in the background, and there is no install, no license server and no version to keep current.
The other real difference is what happens after the sculpt. A ZBrush high-poly is the start of a long trip: retopologize, unwrap, bake, then texture somewhere else entirely. Mold hands the sculpt to Mixos Paint with fresh UVs in one click, ready for layered PBR materials, masks and wear — so the path from blockout to a textured, exportable asset stays inside one browser tab.
It is also free to sculpt. Every brush, every subdivision level, dynamic topology, remeshing, masking, symmetry, multi-object scenes and rigging are available on a free account, with no time limit and no watermark on your work. A paid plan is what lets you export the finished mesh as GLB, OBJ or STL — so you can learn the tool, block out a model and take it all the way to textured before deciding whether it's worth paying for.
Mold is free to sculpt on any Mixos account — all the brushes, subdivision levels, dynamic topology, remeshing, masking and symmetry, with no trial clock and no watermark on your work. Exporting the finished mesh as GLB, OBJ or STL is on a paid plan. Blender is the other serious free option: it sculpts well and it's fully free including export, but it's a desktop install and a much larger program to learn.
For learning to sculpt, concepting, hobby work, 3D printing prototypes and game-ready props — realistically yes. For professional character and creature pipelines, no: ZBrush's brush depth, ZRemesher, ZModeler and its ecosystem of plugins and studio workflows go far beyond what a browser tool covers today. We'd rather you knew that up front than found out three days in.
A browser with WebGPU — current Chrome or Edge on Mac, Windows or Linux. No install and no plugin. It also runs on iPad and phones with a touch-first layout, including Apple Pencil pressure, which is something the desktop ZBrush license doesn't cover.
Within your device's budget, yes. Multiresolution subdivision takes a base mesh to as many as six million triangles on a desktop with 8 GB or more of memory, 1.5 million on an iPad and 1 million on a phone, and Divide and remeshing run in the background with progress. It won't match a workstation running ZBrush on a 40-million-polygon production sculpt, but it holds up well past the point most work needs.
No — ZBrush's tool format is proprietary and isn't readable here. Export your sculpt from ZBrush as OBJ, FBX or GLB and import that instead. On a desktop a dense mesh keeps up to a million triangles of its detail, and Rebuild levels can turn it back into a multiresolution sculpt you can step down through.
One click unwraps it with fresh UVs and opens it in Mixos Paint, a layer-based PBR texture painter — paint materials, add masks and edge wear, then export standard map sets for Blender, Unreal, Unity and the rest. That handoff is free too; only the final export needs a plan.
Yes — a field-aligned quad remesh rebuilds the sculpt as all quads with edge loops that follow the form, aimed at a face count you set, keeping face-set borders and sharp creases, with an optional mirrored X half. ZRemesher is still the benchmark for production retopology, and hand-built topology for an animated hero character is still a job for a dedicated tool.
