Full Comparison
| Criterion | KIRI Engine | Sloyd |
|---|---|---|
| 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. | lower value Free tier; paid from $15 / month The Guest tier is personal use only. Plus is $15 / month, or $12.50 billed annually. |
| Free trial | Free Basic plan with unlimited scans and exports | Free Guest tier (1 generation per day) |
| Output | 3D models and Gaussian splats of real objects and scenes, from photos or iOS LiDAR | Game-ready 3D models from text, images or parametric templates |
| 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 | Game-ready 3D assets from text, images or customizable parametric templates |
| Detail and topology | High-poly meshes with millions of vertices, dynamic decimation for polygon reduction, and quad-mesh retopology with unwrapped UVs on Pro | Clean topology optimized for real-time engines, adjustable polygon counts and manifold geometry for 3D printing |
| Rigging and textures | PBR materials with normal maps and textures up to 8K, plus automatic rig generation, both on the Pro plan | Auto-rigging, AI animation and retexturing with up to 4K textures |
| 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 | Real-time generation in seconds |
| 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 | FBX, GLB, OBJ, USD and USDZ export; plugins for Unity, Unreal, Godot, Maya and Blender |
| 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 | Included with paid subscriptions; Pro adds reselling. The free Guest tier is personal use only |

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
Sloyd
Strengths
- Unlimited generations on paid plans, with no per-model credit caps
- Parametric templates give precise, consistent control
- Auto-rigging, animation and up to 4K retexturing built in
Limitations
- Free Guest tier is personal use only and limited to one generation per day
- Commercial reselling requires the top Pro tier
