V0: Buy Custom Domains Directly in Chat
V0V0 added the ability to purchase and attach custom domains to projects directly from the in-chat sidebar, removing the need to navigate to a separate domain registrar or Vercel dashboard.
Purchase Custom Domains Without Leaving V0
V0 introduced in-chat custom domain purchasing in December 2025, integrating domain registration directly into the project sidebar.
The Workflow
The custom domain feature lives in the in-chat sidebar alongside other project settings. Users can search for available domain names, purchase them, and have them automatically associated with the current project's deployment through Vercel's infrastructure.
Filling a Gap in the Build-to-Deploy Flow
Prior to this addition, deploying a v0 project to a custom domain required leaving the v0 interface. Community discussions on the Vercel forum reflected demand for this streamlined path. The feature complements other recent sidebar improvements, reinforcing v0's direction toward being a complete, self-contained deployment environment.
