v0 has redefined how teams prototype web UIs. By outputting clean, idiomatic React + Tailwind + shadcn/ui code (rather than visual mockups or proprietary markup), it slots directly into modern Next.js workflows and gives engineers a real starting point — not a throwaway. The screenshot-to-code path is genuinely impressive: paste a competitor's hero section or a Figma export and v0 produces a usable component. The free tier is generous enough to evaluate seriously, and the Premium plan at $20/mo unlocks higher message limits and priority generation. Where v0 still lags is complex multi-page interactivity and stateful logic — it shines for visual generation but typically needs human glue for full product features. For solo founders, designers, and frontend engineers, it has rapidly become a default first stop when starting a new screen or product.
v0 is Vercel's AI tool for generating React components, full pages, and apps from natural-language prompts or screenshots. It outputs production-quality code (Tailwind CSS and shadcn/ui by default) that you can edit live in the browser, sync to a Vercel project, or copy into any Next.js codebase. Increasingly used as a starting point for MVPs and as an API endpoint for agentic UI workflows.
