v0 is Vercel's generator for user interfaces and full Next.js apps. Its output usually uses the App Router, React Server Components, Tailwind CSS and shadcn/ui, and projects deploy straight to Vercel. Databases and auth often arrive through Vercel Marketplace integrations such as Neon or Supabase, with credentials stored as Vercel environment variables.
The interface is often the strongest part. Underneath, lists may be filled with hard-coded sample data, forms may call server actions that never write to a database, and authentication may be a styled page with no session handling. Some projects were assembled from several separate v0 chats, so styling and component conventions differ between pages.
Sync the project to a GitHub repository you own and make sure the latest chat output has been committed. List the environment variables the app expects, by name only, and which integrations created them. Check that no keys were pasted into client components, a common slip the secret leak scanner can catch. Then describe which screens must be backed by real data first, since that order shapes the estimate more than anything visual.

AI app builders are excellent for prototypes. These are the gaps that usually appear when a prototype meets real users, real data and a real domain, and how to close them.

ReadNo. Next.js apps can run on other hosts that support Node.js, though some Vercel-specific features may need replacing. Most developers keep Vercel during a rescue because it is already configured.
Invite them to your Vercel team with an appropriate role, or transfer the project to a team you own if it currently sits under a personal account. Keep the GitHub repository under your control as well.
