KIRI Engine vs Meshroom

KIRI Engine is a 3D scanning application that creates models and visualizations using photogrammetry, Neural Surface Reconstruction, and 3D Gaussian Splatting. Photo Scan creates 3D models from photos. LiDAR Scan supports model scans, floor plans, and quick scene visualizations on LiDAR-equipped iOS devices, while Featureless Object Scan is designed for shiny, reflective, transparent, and low-texture objects. The free Basic plan costs nothing and permits up to 150 photos and 2 GB per scan, with unlimited scans and free exports. Pro costs $17.99 a month or $79.99 a year, and raises the limits to 500 photos and 5 GB per scan while adding faster queue processing and advanced scanning and modeling features. The API offers Photo Scan, Featureless Scan, and 3DGS Scan; each API call uses one credit. Credits cost 1.00 USD each, with a 500-credit minimum recharge and 10 free test credits at sign-up. Other listed tools include a website model embedder, a UE5 plug-in, and STL export. Uploaded photos and videos are processed on cloud servers, and local PC scanning is not on the company's roadmap at the moment.

Meshroom is a free, node-based visual programming toolbox for creating and running data-processing pipelines. Its AliceVision plugin combines photogrammetry, camera tracking, HDR panorama, lidar meshing, raw image conversion and color calibration workflows. Users connect operations visually to set dependencies, data flow and execution order. Pipelines can run locally or on distributed systems, including local and remote computation in one project. The meshroom_batch command-line interface and JSON pipeline definitions support automated, reproducible execution. Meshroom reuses cached intermediate results and invalidates affected downstream nodes when attributes change. Built-in viewers display logs, images, 3D data and node outputs. Dynamically loaded plugins can run in separate virtual environments, while Meshroom Hub offers domain-specific plugins for computer vision, AI and other tasks. Prebuilt desktop releases are available for Linux and Windows; macOS requires manual packaging. The software is linked to the Mozilla Public License 2.0. Its listed plan costs nothing.
