About

CustomName is a client-side Fabric mod for Minecraft *.21.11 that lets players replace the default Minecraft client branding with a name they choose. It creates and loads ******/customname.json automatically, exposing a clientName field that requires no source changes to edit. The configured name appears in the game window title and title screen branding alongside the game version. Mixins integrate the replacement into vanilla client rendering while keeping the mod lightweight and server-independent.
