v0

v0 is the UI generation tool by Vercel, the team behind Next.js. From a natural-language prompt or screenshot, v0 produces a React + Tailwind CSS + shadcn/ui component ready to paste into your project.

The key differentiator: generated code uses modern React conventions (Server Components, async pages, App Router) and the shadcn/ui design system, which became the de-facto standard in 2026. v0 can also generate full-stack apps with a Next.js backend, Vercel Postgres, and auth.

Vercel integration enables one-click deployment, and the Open in v0 feature lets you instantly clone any component you find on the web to adapt it.
