v0 by Vercel

Overview v0 is Vercel's AI code generator for building React user interfaces from text prompts, screenshots, or Figma files. It emerged in late 2023 as a "generate shadcn/ui components from a prompt" experiment and has since grown into something meaningfully broader — a full stack of AI driven UI, app, and prototype building with a chat interface, an in browser preview, and one click deploys to Vercel. If you write React, you already know why this matters. If you do not, v0 is the smoothest on ramp on the market to shipping a working web app without touching your terminal. The output is production grade React: TypeScript, Tailwind CSS, shadcn/ui components, Next.js App Router by default. This is not a "generates JSX blob and hopes you can integrate it" tool. The code is idiomatic, opinionated in the same way Vercel's ecosystem is opinionated, and drops directly into a modern Next.js project without translation. That opinion is exactly what makes v0 useful — you are not choosing a framework, you are getting one. The model behind v0 is a fine tuned frontier model (currently based on GPT and Claude blends depending on task) that has been trained specifically on modern React patterns, Tailwind design, and Vercel's own component libraries. What that means in practice is that a prompt like "build me a SaaS pricing table with three tiers and a monthly/annual toggle" produces something you can actually ship, not something you spend an hour cleaning up. v0 is aimed at three…
