v0 by Vercel is a generative AI tool that makes website and application creation as simple as describing your ideas in natural language. Built by the creators of Next.js and Vercel, v0 acts like a frontend engineer through a chat interface – you describe the UI and logic you want, and it outputs clean, production-ready React code with Tailwind CSS and shadcn/ui components. The platform combines retrieval-augmented generation to ground the model in best practices, frontier LLMs for reasoning, and a streaming post-processor called "AutoFix" that continuously scans for errors and best-practice violations during and after generation. This ensures that generated code follows modern standards, maintains accessibility, and implements responsive design patterns out of the box. Recently rebranded from v0.dev to v0.app, the platform now positions itself as "the AI builder for everyone" – not just developers but founders, designers, marketers, and other non-technical users. v0 excels at rapid prototyping, generating polished UIs with strong design sense, and creating landing pages, dashboards, and component libraries. The platform supports Figma imports, allowing designers to bridge the gap between design tools and AI-driven development. v0 uses a credit-based pricing model where usage is metered on input and output tokens. The free tier includes $5 of monthly credits, sufficient for exploring and testing. Paid plans offer more credits and advanced features like larger file attachments, Figma import, and API access. All generated code can be exported and deployed directly to Vercel with zero configuration, or used in any Next.js project. While v0 excels at UI generation and rapid prototyping, it's less suited for complex full-stack logic, multi-step flows, and intricate state management.
