VSeeFace

VSeeFace is a free, well-regarded 3D VTubing application: load a VRM or VSFAvatar model and it tracks your face and expressions through a standard webcam — no iPhone or special gear required — with optional support for iPhone/ARKit, hand tracking, and full-body setups if you have them. It’s known for clean, responsive tracking while being fully free, which makes it a common pick for 3D VTubers who want quality without a budget. Windows only, and it speaks the VMC protocol so it slots into larger tracking rigs.
