v0

v0 is an AI assistant from Vercel that generates user interfaces and full-stack web applications from text prompts. It produces working React code alongside a live preview, letting users describe a layout or feature and receive components styled with Tailwind CSS that can be copied into a project or iterated on within the tool.

The product serves web developers, designers, and product teams who want to move from concept to functional interface quickly. Users refine results through conversation, attach reference images, and extend simple pages into complete applications, with tight integration into Vercel's deployment workflow for shipping projects.

v0 runs in the browser on a credit-based model with a free tier and paid plans for expanded usage. Launched in 2023 by Vercel, the company behind Next.js, it has become a widely adopted tool for AI-assisted front-end development.
