KIRI Engine

KIRI Engine is a 3D scanning app for turning photos and supported LiDAR captures into models and visualizations. It best suits makers and 3D practitioners who need different ways to capture subjects, including reflective or low-texture objects. Its appeal is breadth; its trade-offs are cloud processing and firm per-scan caps.

Overview

KIRI combines photogrammetry, Neural Surface Reconstruction and 3D Gaussian Splatting. Photo Scan builds detailed models from photos, while Featureless Object Scan is designed for shiny, reflective, transparent and low-texture subjects that can challenge a photo-based workflow. On LiDAR-equipped iOS devices, LiDAR Scan supports model scans, floor plans and quick scene visualizations.

Uploaded photos and videos are processed on cloud servers to produce models and visualizations. KIRI says transmitted user data is encrypted and used only for notification purposes, but the capture media still leaves the device during reconstruction. That rules it out for users who require local-only processing; running the scanning algorithm locally on a PC is not on the company’s roadmap at the moment.

Key features

Capture and modeling tools

The choice of scan methods is KIRI’s clearest advantage: users can choose photos, LiDAR where supported, or a mode aimed at difficult surfaces. Pro adds PBR materials, quad mesh, automatic rig generation and mesh-inclusive 3D Gaussian Splatting scans. Those additions make the paid tier more relevant to users who need modeling options beyond reconstruction, though Basic remains limited to 150 photos and 2 GB per scan.

Exports and integrations

KIRI supports point-cloud export and free exports on both Basic and Pro. The pricing page also describes a website 3D model embedder, a UE5 plug-in for 3DGS, and STL export for 3D printing. These options make the app useful beyond viewing a scan, particularly for users placing models on websites or preparing prints.

API

The API supports Photo Scan, Featureless Scan and 3DGS Scan; each call costs one credit regardless of method. This straightforward accounting suits occasional or metered integrations, but the minimum 500-credit recharge makes API access a substantial upfront commitment. New sign-ups receive 10 free test credits.

Pricing

Plan	Price	What it includes
Basic	Free	Up to 150 photos and 2 GB per scan, with unlimited scans and free exports
Monthly Pro Plan	USD 17.99 per month	Up to 500 photos and 5 GB per scan, faster queue processing, advanced scanning and modeling features, and unlimited free exports
Yearly Pro Plan	USD 79.99 per year, equivalent to USD 6.66 per month	The same Pro allowances and features as the monthly plan
API credits	USD 1.00 per credit, once; minimum recharge 500 credits	One credit per API call; 10 free test credits at sign-up

Basic is a meaningful starting point for smaller captures: scans and exports are unlimited, but each scan stops at 150 photos and 2 GB. Pro raises those caps to 500 photos and 5 GB and adds faster queue processing plus advanced tools. Monthly Pro suits users who want those additions without a yearly commitment; Yearly Pro is the lower-cost option for sustained use. API credits are separate from the app plans and are better suited to integration needs than ordinary scanning.

Platforms

KIRI Engine is available on Android, iOS, web and API. LiDAR Scan is specifically for LiDAR-equipped iOS devices, so Android users should not expect that capture method. Cloud processing also means the product does not serve users seeking an offline PC scanning workflow.

Who it's for

KIRI is a strong candidate for 3D printing enthusiasts, 3D artists and scientific researchers who can work within its capture limits and send media to cloud servers. The free tier should cover smaller or exploratory projects; Pro is more appropriate when larger captures, faster queue processing or the additional modeling tools matter. Users handling sensitive capture media that must stay local should look elsewhere.

Pros and cons

• Pros: Photo, LiDAR and featureless-object scanning give users several capture routes for different subjects.
• Pros: Basic includes unlimited scans and free exports, making it practical for repeated smaller projects.
• Pros: Pro increases both photo and file-size limits and adds faster processing and modeling tools.
• Cons: Basic’s 150-photo and 2 GB per-scan caps constrain larger captures.
• Cons: Cloud reconstruction requires uploading photos or videos, and local PC processing is not on the roadmap.
• Cons: API use has a 500-credit minimum recharge even though each call costs one credit.

Alternatives

For a different mobile scanning option, Polycam has a free plan with limited space, object and AI captures, GLTF exports and public link sharing; consider it if those outputs and sharing fit your needs. If running the software locally and offline is the priority, WebODM is free to install and use and supports those workflows. RealityScan is another freemium alternative with a free plan and free trial.

3DF Zephyr offers a free personal-use Windows edition capped at 50 photos or video frames, with limited exports and editing. PIX4Dcatch is another freemium option. Agisoft Metashape is a paid alternative with a free trial and a Standard Edition priced at USD 179.00 per month. Krynth has a free web plan limited to one Quartz scan per month, with watermarked output and 14-day hosting. Artec Studio is a paid Windows option with a 30-day Pro trial that does not allow saving or exporting projects.

Verdict

Choose KIRI Engine if you want several scanning methods, especially a dedicated option for difficult surfaces, and can accept cloud reconstruction and per-scan limits. Basic is a useful low-commitment starting point, while the yearly Pro plan is the more economical route to higher caps and modeling features for regular use. Look elsewhere if your work requires local processing or unrestricted capture sizes.
