VTuber Zukan is a free, unofficial database that shows the relationships between VTubers and their creators: character illustrators ("mama"), Live2D and 3D modelers, and others. Instead of a simple list, it draws an interactive relationship graph, so you can see at a glance which artists worked on which VTubers and how creators connect to each other. Credits are recorded per outfit and model version, and every entry is linked to a primary source such as an official announcement on X or a stream description. The site is an independent project by Ren Vale and is still growing, with more VTubers and creators being added over time.
