vsSculpty vs SPAR3D
SPAR3D reconstructs a mesh from a single image in under a second, with open weights you can download and a licence that permits commercial use. It is one of the most impressive things in this directory, and it is a model rather than a product — which is the whole comparison.
SPAR3D wins on speed by an order of magnitude and on cost of ownership if you already run GPUs: no per-generation charge, no vendor, weights you keep. Its point-cloud conditioning also gives editing control the commercial engines do not expose. What you get with Sculpty instead is a product: text prompts, five engines, multi-view, texturing, remesh, renders, worlds, a gallery, print ordering, and nothing to deploy. If you have an ML team, SPAR3D may be the better foundation. If you want to make something this afternoon, it is not close.

- Public API — Available through the Stability AI developer platform as well as self-hosting.
- Free plan or trial — Open weights are free to run — you supply the GPU. There is also a hosted API.
Sculpty runs five engines, not one
Every engine answers the same prompt box. When one misreads what you asked for, switching costs a dropdown instead of another subscription.

Both sides, fairly.
Sculpty- Five AI 3D engines in one studio — pick the best one per prompt instead of being locked to a single model
- The whole pipeline after generation: AI texturing, remesh and retopology, photoreal renders, explorable 3D worlds
- Export GLB, STL, OBJ, PLY and glTF, plus native FBX, USDZ and 3MF on Meshy generations
- Free format converters and a browser 3D viewer, no sign-up required
- Order a physical 3D print of any model without leaving the app
- Free plan to try every engine, then $14/mo
- No public API yet — Sculpty is a studio, not an engine you can call from your own code
- No auto-rigging or animation tooling
- Younger platform than the engines it runs, with a smaller community
- Sub-second reconstruction — the fastest thing in this list by an order of magnitude
- Open weights under a licence that permits commercial use
- Point-cloud conditioning gives real editing control over the reconstruction
- Predicts complete object structure, including the parts the photo does not show
- A model, not a product: no gallery, no account, no support
- Image input only — no text prompts, no multi-view
- Self-hosting means GPUs and engineering time
- No texturing, remesh, render or world tooling
The cost that does not appear on either pricing page
Open weights are free the way a puppy is free. You need GPUs with enough memory, an inference service, monitoring, someone to update it, and a viewer to look at the output — and none of that produces a single asset until it is finished. That investment pays off at volume or when you need to modify the model itself. Below that threshold, a hosted studio on credits is dramatically cheaper in the only currency that matters, which is your time.
Frequently asked questions.
Is SPAR3D really free for commercial use?+
The weights are published under Stability AI's Community License, which permits commercial and non-commercial use. You supply the compute, or pay for their hosted API.
Can SPAR3D take a text prompt?+
No — single image only. Sculpty runs four text-to-3D engines.
