Live3D

Live3D has a free version, though the more advanced features sit behind a paid subscription. It is a VTuber software suite that lets you build avatars, animations and interactive streaming setups, with a focus on 3D VTuber models rather than 2D ones.

Live3D tracks your face and hands, so your avatar can follow your movements on camera.

A customizable VTuber editor lets you adjust a model, and a library of ready-made VTuber models and assets gives you a starting point if you do not want to build from scratch.

There are also interactive tools made for streamers, and the resources are updated on a continuing basis.

The category list also covers anime, cartoon, sticker and sketch generation, colorizing and background generation, so Live3D reaches beyond live avatars.

One catch: the Apple Store review process can delay releases of the VTuber app, so iOS updates may arrive later than you expect.
