Editorial Verdict
Best for
3D printing enthusiasts needing quick, accurate scansGame developers creating real-time assets with 3DGSArtists capturing real-world objects for digital artDesigners and engineers for product prototypesArchitects/interior designers using LiDAR floor plans
Not ideal for
Professional industrial metrology requiring sub-mm accuracyUsers who need fully offline processing (cloud-based only)Scenes with heavy occlusion or fine hair/fur (photogrammetry struggles)Those seeking a pure desktop software (no desktop app, only mobile/web)Remote field work without reliable internet connection
KIRI Engine delivers the most feature-rich free 3D scanning experience on mobile, especially with NeRF and 3DGS included. The Pro upgrade is reasonably priced for the advanced tools, but cloud-only processing and lack of offline mode limit its use in remote settings. If you need a versatile scanner without upfront cost, this is hard to beat.

About KIRI Engine
FreemiumBeginner-friendlyAPI availableMobile · Web · Plugin
KIRI Engine is a mobile-first 3D scanning app for iPhone, iPad, and Android that combines photogrammetry, LiDAR capture, NeRF-based featureless scanning, and 3D Gaussian Splatting (3DGS) into a single tool. It's designed for 3D printing enthusiasts, game developers, artists, and engineers who need quick, production-ready 3D assets without complex desktop software. The app offers four scanning modes: Photo Scan (traditional photogrammetry), LiDAR Scan (room/object/scene capture on iOS), Featureless Object Scan (NeRF-derived, for shiny/transparent/low-texture objects), and 3DGS Scan (ultra-realistic real-time renders with mesh export). Advanced features include AI-generated PBR materials (albedo, roughness, normal, displacement maps), quad mesh retopology with clean UVs, auto-rigging for animation, and dynamic decimation. Exports support OBJ, STL, GLTF, FBX, USDZ, and mesh-included 3DGS formats. Processing runs in the cloud, with unlimited free exports on the Basic plan—rare among competitors. The free tier includes photogrammetry, LiDAR scans, cropping/texturing tools, high-poly export, and unlimited photo uploads via the web companion. Pro subscribers (USD 79.99/year or USD 17.99/month) unlock featureless scanning, 3DGS with mesh, PBR materials, quad mesh, auto-rigging, faster processing, and 500 photos per upload. Compared to Polycam and Luma AI, KIRI Engine stands out for its generous free tier and built-in NeRF/3DGS support. It's not a replacement for high-end desktop photogrammetry suites (e.g., RealityCapture) for sub-mm metrology, but for quick, affordable mobile scanning, it's a top choice.
Behind the Verdict
KIRI Engine nails the mobile 3D scanning use case better than most. The free tier is genuinely usable—unlimited exports, no watermarks, and access to both photogrammetry and LiDAR scans. That alone makes it a go-to for hobbyists and students. Where it really shines is the advanced scanning modes. The Featureless Object Scan (NeRF-based) handles shiny, transparent, or monochrome objects that stump traditional photogrammetry apps. The 3DGS mode with mesh export is a differentiator, letting you create real-time renders that are actually editable in other 3D software. For game assets and digital art, that's a huge time-saver. When to pick it: you're a 3D printer needing quick scans of everyday objects, a game developer prototyping assets, or an artist capturing real-world textures. When to pass: you need sub-mm accuracy for industrial inspection, work offline in the field, or want a fully desktop-based workflow. The cloud dependency is real—no processing without internet. Compared to Polycam, KIRI Engine offers more free features and includes 3DGS/NeRF at a lower price point. Polycam has a better web platform and slightly more polished UI, but KIRI's free tier is far more generous. Compared to Luma AI, KIRI is less focused on NeRF-only and gives you traditional photogrammetry too—more versatile but less specialized. One caveat: processing queue times can be slow on the free tier. Pro users get faster queuing, but even then, large scans can take hours. For quick turnaround, keep your capture sets small. Also, the app occasionally crashes on older Android devices—test before committing to a workflow.

Use Cases
- Scan a shiny ceramic mug using Featureless Object Scan for 3D printing.
- Capture your living room with LiDAR Room Scan to create a floor plan.
- Photograph a small sculpture with Photo Scan and export as OBJ for game engine.
- Record a 3D Gaussian Splatting scene of a garden and export with mesh for VR.
- Use auto-rig feature to create an animated character from a scanned figurine.
Limitations
- The free tier limits local photo upload to an unspecified number (Pro increases to 500 photos per upload).
- Processing speed is slower on free tier due to queuing.
- Featureless Object Scan, PBR Materials, Quad Mesh, and Auto Rig Generation require a Pro subscription.
- The app relies on cloud processing, so internet is required for most operations.
