v0

v0, by Vercel, is the market-leading example of a Generative UI platform. It is crucial to understand that v0 is not a full-stack application builder but rather an "AI assistant to design, iterate, and scale" user interfaces for the web. Its core function is to generate high-quality, production-grade React components using Tailwind CSS and shadcn UI from simple text prompts. The platform embodies the "vibe" aspect of development for designers and frontend engineers, allowing them to rapidly experiment with UI/UX concepts. A user can start with a prompt like "a financial dashboard" or "a crypto app with a dark mode theme" and iteratively refine the output through conversation. What sets v0 apart are its advanced, agentic capabilities that go far beyond simple generation.
