VNyan

VNyan (by Suvidriel) is a free, made-by-a-VTuber 3D VTubing app built for interactivity: a node-graph interface lets you wire up custom reactions, props, and physics, and it’s the one with deep Twitch integration — channel events, hype-train detection, and Twitch/7TV/BTTV/FFZ emotes can all drive things on screen. Under the hood it handles VRM and VSFAvatar models, a wide range of tracking (webcam ARKit, iPhone, LeapMotion, VR full-body, and VMC inputs), and standout physics like pendulum chains for wobbly eyes and flowing hair. It’s completely free with no paywalls, and the developer notably builds it without generative AI. Windows only.
