Meshy vs Stable Fast 3D

Meshy creates 3D assets from text, images, or creative concepts for users to preview, edit, and export. Text-to-3D generates textured models from written descriptions, while Image-to-3D works from photos, sketches, or concept art. It can auto-rig humanoid and quadruped characters and offers more than 600 motion presets. For 3D printing, Meshy says its models are watertight and manifold; its printability check scans exports and can repair some edge cases. Integrations include Blender, Unity, Unreal Engine, Godot, Roblox Studio, Bambu Studio, OrcaSlicer, and Creality Print, along with a REST API and MCP server. The Android and iOS app syncs with the web app and exports formats including STL, GLB, FBX, OBJ, USDZ, and 3MF. The web app has a 100 MB upload limit for AI texturing and accepts one model at a time. Meshy has a free plan; Pro starts at $20 a month. Free-plan assets use CC BY 4.0 and require attribution for commercial use.

Stable Fast 3D turns an image of an object into a textured, UV-unwrapped 3D mesh. Stability AI describes the model as generating a 3D model from one image in under one second. It expects a 512 × 512 pixel input, applies a delighting step, and predicts roughness and metallic material parameters. The official code example saves the result as a GLB file. The repository includes custom nodes and an example workflow for ComfyUI, and API access is available. Documented inference options include CUDA, CPU, and experimental Mac MPS; Windows support is marked experimental. Default settings use about 6 GB of VRAM for one image. Stability AI identifies game and VR developers and professionals in retail, architecture, and design among its intended users.
