No-code / low-code 3D & motion graphics for the web — Spline (3D scenes with @splinetool/react-spline), Rive (interactive 2D and 3D state machines via @rive-app/canvas, @rive-app/react-canvas, @rive-app/webgl2). Use when a designer ships a .spline scene or .riv file, you need an interactive hero/illustration without writing Three.js, or for runtime-controlled state-machine animations.
