Best for
Best for developers with their own GPU who want an open, MIT-licensed image-to-3D model to run and adapt themselves.
Cataleo does not name a winner. Both statements come from the vendors themselves.
Full Comparison
| Criterion | KIRI Engine | TRELLIS |
|---|---|---|
| Starting price | Free tier; Pro from $17.99 / month Pro is $17.99 billed monthly or $79.99 per year. The free Basic plan includes unlimited scans and unlimited exports. | Free, MIT licence Needs your own hardware: Linux and an NVIDIA GPU with at least 24 GB of memory, verified on A100 and H100. |
| Free trial | Free Basic plan with unlimited scans and exports | Free open weights, plus a Hugging Face Spaces demo |
| Output | 3D models and Gaussian splats of real objects and scenes, from photos or iOS LiDAR | Textured 3D assets in GLB, as radiance fields, 3D Gaussians or meshes |
| API | Yes, a 3D scanning API billed per call in credits | Run from the published code and weights; an Azure AI Foundry instance is available |
| Hosting | Not stated | Self-hosted |
| What it makes | 3D models and Gaussian splats of real objects and scenes, captured from phone photos, iOS LiDAR or the web app | 3D assets from image prompts in TRELLIS.2, and from text or image prompts in the first release, decoded as radiance fields, 3D Gaussians or meshes |
| Detail and topology | High-poly meshes with millions of vertices, dynamic decimation for polygon reduction, and quad-mesh retopology with unwrapped UVs on Pro | The O-Voxel sparse voxel structure represents open surfaces, non-manifold geometry and enclosed internal structures without a lossy conversion |
| Rigging and textures | PBR materials with normal maps and textures up to 8K, plus automatic rig generation, both on the Pro plan | Native PBR materials with base colour, roughness, metallic and opacity |
| Speed | Processing runs on KIRI's servers and takes from a few minutes for a quick scan to 20 to 30 minutes for an intensive one, depending on how many photos or how much video went up. A shared global queue sits in front of that, and Pro adds priority queueing | On an H100, about 3 seconds at 512 cubed, 17 seconds at 1024 cubed and 60 seconds at 1536 cubed |
| Export and pipeline fit | OBJ, FBX, STL, GLB, GLTF, USDZ, PLY and XYZ from Photo Scan and Featureless Object Scan; OBJ and USDZ from LiDAR Scan; PLY natively for Gaussian splats, with mesh export on Pro | GLB export; runs on Linux with an NVIDIA GPU of at least 24 GB and CUDA Toolkit 12.4 |
| Commercial use | The scans you create and export belong to you, on the free plan as well as on Pro. KIRI notes separately that a scan of a proprietary object may still be covered by someone else's copyright, so the rights in the subject are a different question from the rights in the file | MIT licence for the model and the code; dependencies such as nvdiffrast and nvdiffrec carry their own licences |
| Deployment | Cloud (SaaS), Browser-based | Browser-based, On-premise |
| Support | Email helpdesk, Community forum | Not stated |
| Onboarding | Documentation and knowledge base | Not stated |
| Company size | Freelancers, Small and mid-sized | Not stated |
| Integrations | Not stated | Hugging Face, Azure AI Foundry |

The trade-offs
Strengths and Limitations
KIRI Engine
Strengths
- Free plan includes unlimited scans and unlimited exports rather than paywalling export formats
- Featureless Object Scan handles reflective, transparent and untextured objects that photogrammetry misses
- Runs on iPhone, Android and in the browser, so a LiDAR device is not required
Limitations
- PBR materials, quad-mesh retopology and auto rig generation are Pro only
- LiDAR Scan needs a LiDAR-equipped iOS device and exports only OBJ and USDZ
- The free plan caps a scan at 150 photos and 2 GB
TRELLIS
Strengths
- MIT licence covering both the code and the pretrained weights
- Represents open surfaces, non-manifold geometry and internal structures
- Native PBR output with base colour, roughness, metallic and opacity
- Seconds per asset at 512 cubed on an H100
Limitations
- Needs Linux and an NVIDIA GPU with at least 24 GB of memory
- A research release on GitHub and Hugging Face rather than a packaged product with support
- TRELLIS.2 takes images only; text prompting is in the first release
Plans
Pricing
KIRI Engine
- Basic $0 Unlimited 3D scans and unlimited exports. Photo Scan and LiDAR Scan, in-app cropping and texturing, high-poly export, dynamic decimation and access to the web platform. Up to 150 photos and 2 GB per scan.
- Pro $17.99 Per month, or $79.99 per year. Adds Featureless Object Scan, mesh-inclusive 3DGS, PBR materials, quad-mesh retopology and auto rig generation. Up to 500 photos and 5 GB per scan, with queue priority.
TRELLIS
