v0 by Vercel

The fastest way to generate polished React interfaces

v0 turns prompts and screenshots into React components built on shadcn/ui and Tailwind. It is a UI specialist rather than a full-stack builder, and it is unbeaten at producing clean, idiomatic front-end code you can paste straight into an existing project.

• Code ownership — Full source
• Database — Not included
• Authentication — Not included
• Deploy — Vercel
• Best first project — A single high-polish page

• Component output is idiomatic and readable
• shadcn/ui and Tailwind by default
• Screenshot-to-UI works surprisingly well
• Slots into an existing Next.js codebase cleanly

• Backend and data layer are on you
• Strongest inside the Vercel ecosystem
• Full multi-page apps need stitching together

• Front-end developers
• Designers
• Marketing pages

Treat v0 as the component factory in your stack rather than the whole factory. For interface work it is still the sharpest tool available.
