v0 by Vercel is an AI UI generation tool that creates production-ready React components and full page layouts from text prompts and screenshots — outputting code built with shadcn/ui components, Tailwind CSS, and TypeScript that developers can copy directly into their projects. Unlike AI builders that generate hosted sites, v0 is specifically a code generation tool for developers — the output is a React component, not a deployed website. It's integrated into Vercel's ecosystem and used by developers to rapidly prototype UI components, landing pages, and admin interfaces. Sites where developers have deployed v0-generated code may include generated-by-v0 comments or v0.dev references in their markup, though this is optional attribution. v0 is accessible at v0.dev with a free tier and Pro access included with Vercel Pro.
