Full Comparison
| Criterion | KIRI Engine | Marble |
|---|---|---|
| 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. | Not stated |
| Free trial | Free Basic plan with unlimited scans and exports | Free plan with up to 4 world generations |
| Output | 3D models and Gaussian splats of real objects and scenes, from photos or iOS LiDAR | Explorable 3D worlds as Gaussian splats, meshes or video |
| API | Yes, a 3D scanning API billed per call in credits | Yes |
| What it makes | 3D models and Gaussian splats of real objects and scenes, captured from phone photos, iOS LiDAR or the web app | Explorable 3D worlds as Gaussian splats, meshes or video |
| Detail and topology | High-poly meshes with millions of vertices, dynamic decimation for polygon reduction, and quad-mesh retopology with unwrapped UVs on Pro | Splats at about 2M or 500k; meshes at about 600k triangles textured, 1M vertex-coloured, plus a 100-200k collider mesh |
| Rigging and textures | PBR materials with normal maps and textures up to 8K, plus automatic rig generation, both on the Pro plan | No rigging or animation, the output is an environment rather than a character. Collider mesh export is included from the Standard plan, textured GLB export requires Pro |
| 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 | High-quality mesh export takes up to an hour, limited to 4 requests per hour |
| 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 | SPZ and PLY splats, GLB meshes, 360 panorama PNG; guides for Unreal Engine, Unity, Blender and Houdini |
| 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 | Commercial rights included from the Pro plan |
| Deployment | Cloud (SaaS), Browser-based | Cloud (SaaS), Browser-based |

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
Marble
Strengths
- Generates navigable worlds rather than single objects
- Takes text, images, video, 360 panoramas or a coarse 3D layout as input
- Chisel blocks out world structure in 3D before generating
- Worlds can be expanded and composed into larger spaces
- Documented export routes into Unreal Engine, Unity, Blender and Houdini
Limitations
- Commercial rights only from the Pro plan upwards
- Free plan covers only four world generations
- High-quality mesh export takes up to an hour and is rate limited
- High-quality meshes can only be generated on worlds you own
Plans
