CloudRig
CloudRig is currently the primary Rigging System used in the Blender Studio.
This auto-rigger started out as an “Extension” for Rigify. However since Blender 4.1 it has become a separate addon.
Nevertheless, if you are familiar with Rigify, CloudRig should be easy to get started with.
If you’re looking to get deeper into customizing your CloudRig, you’ll find learning resources in this article.
