RadianceKit: Native macOS app for 3D Gaussian Splatting on Apple Silicon

A snack-sized bagel for a snack-sized appetite.
Summary
RadianceKit is a native macOS app for 3D Gaussian Splatting, developed by solo developer Björn from Germany. It allows users to drop in photos or video and get a photorealistic 3D reconstruction entirely on-device using Apple Silicon's Metal framework — no Python, CUDA, cloud, or external dependencies required. The app features Simple Mode for one-click results, Scene-Class Presets (Render/Outdoor/Indoor), Expert controls, and exports to 6 formats. Priced at $7.99 one-time with a 3-day trial, it runs on M1+ Macs.
Key quotes
· 3 pulledI built RadianceKit because I was fascinated by 3D Gaussian Splatting but frustrated by the workflow: install Python, set up CUDA, run COLMAP, fiddle with command-line scripts... all on a Linux box or a beefy NVIDIA rig.
I thought: this should just be an app. Drop in photos, get a 3D scene back.
So I rewrote the entire pipeline in Metal for Apple Silicon. No external dependencies, no cloud — everything runs locally on your Mac.
