Mixos Mold

Overview

Mixos Mold is browser-based software for sculpting organic 3D forms with GPU tools and pressure-sensitive brushes. It suits artists who want to work across devices without installing a sculpting app. Its broad sculpting toolkit is a clear draw, but the free plan cannot export a finished mesh.

Projects saved to an account can be reopened on other devices after sign-in. The maker says editing runs locally in the browser and that projects, models, textures, brushes and prompts are not used to train AI models. Projects are stored after account save, but Mixos has no SOC 2, ISO 27001 or equivalent audit, or uptime guarantee. That distinction matters to studios weighing a browser workflow for production work.

Mixos is a one-person operation based in New York, led by founder Matthew Guild. Its stated audience includes game artists, motion designers, 3D hobbyists, students and studios.

Key features

Sculpting and topology

Mold combines subdivision, dynamic topology, masking, symmetry, stamp alphas, brush presets and remeshing. Automatic retopology, multiresolution sculpting and voxel sculpting broaden the toolkit for different modeling approaches. Free users get unlimited sculpting, every brush and every subdivision level, making the free tier useful for learning and developing forms. The catch is decisive for anyone finishing work outside Mold: mesh export is locked behind a paid option.

Models, texturing and handoff

OBJ, FBX and GLB imports let users bring existing models into the sculpting workflow. Mold can unwrap a sculpt and send it to Mixos Paint for layered PBR texturing, a focused handoff for users who want to continue inside the Mixos ecosystem. The broader Mixos desktop app's Live Link streams materials into Blender, Cinema 4D and Unreal, but that is a separate handoff capability rather than a Mold export format.

Browser and device workflow

Mold runs without installation in WebGPU-capable browsers: Chrome, Edge, Firefox or Brave, and Safari 26+ on desktop. It also runs on iPad and Android devices in a WebGPU-capable browser; the Mixos iOS app includes Mold for iOS 26 or later. This reach favors users moving between devices, though the browser requirement makes WebGPU compatibility essential. Email support is available at [email protected], and in-app feedback includes the app version.

Pricing

Mold is freemium, with no free trial. The free plan costs 0.00 USD per free (billed $0 forever). It includes unlimited Mold sculpting, every brush and subdivision level, 10 trial AI credits and 100 MB cloud storage. It is a capable sculpting tier, but finished-mesh export requires an upgrade.

Pro costs 8.99 USD per month (billed $8.99/mo; billed monthly). It adds GLB, OBJ and STL mesh export, 50 AI credits/month, 25 GB cloud storage and email support. This is the practical choice for regular users who need to download finished work without a large storage requirement.

Max costs 17.99 USD per month (billed $17.99/mo; billed monthly). It includes everything in Pro, raises the allowance to 150 AI credits/month and storage to 50 GB, and adds priority support. The higher tier is most relevant to users who need the larger quotas or priority help; it does not change the listed export formats.

The perpetual license costs 99.00 USD per once (billed $99 once). It includes 4K watermark-free export forever, mesh export and 20 GB cloud storage, while AI credits are sold separately. It avoids a monthly subscription for users focused on exported meshes, but offers less storage than Pro and does not include an AI credit allowance.

Platforms

Mold supports web, Windows, macOS, Linux, iOS and Android. Desktop browser use requires WebGPU and one of the named browsers; mobile use also depends on a WebGPU-capable browser, except that Mold is included in the Mixos iOS app for iOS 26 or later.

Who it's for

Mold is best suited to game artists, motion designers, students and hobbyists who want a broad sculpting toolkit in a browser and can accept a paid export route. Its free plan is especially useful for sculpting practice and saving work to a library. Studios should weigh the absence of an equivalent security audit and uptime guarantee before making it a production dependency.

Pros and cons

• Pro: The free tier keeps all brushes, subdivision levels and unlimited sculpting available, so users can develop forms before paying.
• Pro: Import support for OBJ, FBX and GLB, plus a Paint handoff for layered PBR texturing, supports a practical asset workflow.
• Pro: Account-saved projects can be reopened across devices, and the browser-based workflow avoids installation.
• Con: Free users cannot download finished meshes, so the free tier cannot serve as a complete export workflow.
• Con: Browser use depends on WebGPU, with Safari desktop requiring version 26 or later.
• Con: Mixos has no SOC 2, ISO 27001 or equivalent audit or uptime guarantee, a consideration for studios with formal requirements.

Verdict

Choose Mixos Mold if you want a capable, cross-device sculpting workflow and can pay when it is time to export. Its generous free sculpting tier and Mixos Paint handoff are the strongest reasons to start here; look elsewhere if free mesh export or audited enterprise assurances are essential.
