Mate Engine

MateEngine is a lightweight desktop companion app with full custom VRM model support. Bring 3D anime-style characters to life on your screen with idle animations, drag and dance features, and low resource usage and open-source.
Mate Engine supports custom VRM characters, so you can use the free software VRoid Studio to make your own VRM character, or download characters/outfits/accessories (free and paid, you need Pixiv account) from the VRoid Hub:
