Kine UI – Standardizing hand-gesture interaction for React

Summary: Kine UI is an open-source React library for building spatial interfaces using real-time hand-gesture tracking powered by MediaPipe’s vision tasks running in a WebWorker at near 60fps. It provides source code ownership through a shadcn-style registry model without package installation.

What it does

Kine UI enables native hand-gesture primitives in React by off-loading MediaPipe’s vision tasks to a WebWorker, delivering efficient real-time gesture tracking and spatial computing.

Who it's for

Developers building spatial interfaces and gesture-based web interactions in React seeking open-source, performant solutions.

Why it matters

It offers a lightweight, transparent alternative to heavy computer vision libraries with full source code control and near real-time performance on mid-range devices.
