Kine UI is an open-source alternative to heavy, black-box computer vision libraries. Build spatial interfaces, track real-time gestures, and explore native spatial computing — built openly, for everyone, forever free. What makes it different? > Registry Model: Like shadcn/ui, you don’t install a package. You copy the source code. You own the engine (kine-engine.ts) and the components. > It uses MediaPipe’s vision tasks off-loaded to a WebWorker. It runs at near 60fps even on mid-range laptops.
