Gauzilla

Gauzilla Pro is a browser based 3D Gaussian Splatting viewer and editor published by Waldek Technologies, which renders and edits reality models captured with smartphones, drones and 360 cameras without any installation. The application is written in Rust and compiled to WebAssembly, and it runs rendering through WebGL and AI inference on device through WebGPU and ONNX models rather than calling out to a cloud service.

Gauzilla Basic is the free, MIT licensed core, published on GitHub and deployable self-hosted, loading 3DGS models from a URL. Gauzilla Pro is the commercial layer and is now sold through a demo request rather than the waitlist that preceded it. Pro adds Vision Transformer based interactive segmentation, which arrived with segmentation and annotation in March 2024, object level annotation, and WYSIWYG object manipulation covering move, rotate, clone and erase, which arrived as the editing feature set the following month. A real time sharpness filter removes blur from a rendered splat without retraining on the GPU.

The multiple object segmentation path is the technical differentiator. Segmentation of several 3D Gaussian objects runs simultaneously in the browser through WebGPU, which addresses the absence of scene understanding in a raw splat, and running inference on the user's device rather than a server removes the per query cloud cost.

Gauzilla Pro is positioned around 3D and 4D digital twins for four named verticals. In architecture, engineering and construction it tracks jobsite progress against BIM schedules and supports clash detection and logistics planning. In real estate it produces walkable listings. In mining and forestry it monitors stockpile volumes and terrain and vegetation change with what the vendor describes as centimeter level spatial accuracy. In heritage and tourism it produces permanent photorealistic records of sites. A dedicated demolition workflow uses dynamic 4D viewing and editing for demolition simulation, safety and logistics planning, and verification. The 4D time lapse capability generates dynamic reconstructions from multiple 3DGS models, and XGRIDS scan data has been shown running through it in a retail demo.
