v0 by Vercel
v0 is Vercel's AI UI generation tool that creates production-ready React and Next.js components from text or image prompts using shadcn/ui and Tailwind CSS.
v0 is an AI-powered UI generation tool developed by Vercel, designed to bridge the gap between design intent and production-ready frontend code. By simply describing what you want in natural language—or uploading a screenshot or wireframe—v0 instantly generates clean, functional React components that adhere to modern best practices. It combines the power of large language models with Vercel's deep expertise in frontend infrastructure to produce code you can actually ship.
At its core, v0 generates components built on shadcn/ui and styled with Tailwind CSS—two of the most widely adopted frontend libraries in the React ecosystem. This means the output isn't just visually correct, it's architecturally sound and immediately integrable into any Next.js or React project. Components come with proper TypeScript typing, accessibility attributes, and responsive design out of the box, reducing the polish work developers typically face after a code generation step.
The iterative editing workflow sets v0 apart from simple code generation tools. After the initial generation, you can refine components through follow-up prompts—adjusting colors, layout, behavior, or adding new features—all while maintaining code coherence. This conversational refinement loop makes v0 feel less like a one-shot generator and more like a collaborative frontend pair programmer who understands your design system.
v0 also supports image-to-code generation, allowing users to upload mockups, screenshots of existing UIs, or hand-drawn sketches. The model analyzes the visual layout and produces matching component code, dramatically accelerating the process of converting designs into implementation. This capability is particularly powerful for replicating competitor UI patterns, prototyping from Figma exports, or quickly bootstrapping new features based on visual references.
Beyond individual components, v0 can generate full page layouts, dashboard templates, landing pages, and multi-component compositions. The output is copy-paste ready and comes with live preview, enabling developers and designers to validate the output visually before integrating it into their codebase. For teams using Vercel's deployment platform, v0 fits naturally into the existing workflow, complementing tools like Next.js, Turbopack, and Vercel's edge network.

Frequently Asked Questions
Is v0 free to use?
v0 offers a free tier that includes a limited number of generations per day. For heavier usage, Vercel offers paid plans with increased generation quotas and additional features. The free tier is sufficient for individual developers experimenting with the tool or building small projects. Teams and professionals who use v0 regularly typically upgrade to a paid plan for unlimited or higher-volume access.
What tech stack does v0 generate code for?
v0 primarily generates React components built with shadcn/ui and styled using Tailwind CSS. The output is TypeScript-first and designed to integrate seamlessly into Next.js projects, though the components can also be used in any React application. The generated code follows the same conventions as the shadcn/ui component library, making it immediately familiar to developers already using that stack.
Can I use v0 output in non-Vercel projects?
Yes, the code generated by v0 is standard React/Next.js code and is not locked into Vercel's platform. You can copy the generated components and use them in any React project hosted on AWS, GCP, Netlify, or any other platform. The only dependencies are shadcn/ui and Tailwind CSS, both of which are free, open-source libraries you can install via npm.
How accurate is v0 at replicating designs from images?
v0's image-to-code capability is impressively accurate for structured UI layouts such as dashboards, forms, navigation bars, and card-based designs. It correctly interprets spacing, color schemes, and component hierarchy from screenshots. For highly complex or custom-illustrated designs, some manual adjustments may be needed. The best results come from clean, high-resolution screenshots of standard web UI patterns.
Who is v0 best suited for?
v0 is ideal for frontend developers who want to accelerate component development, designers who want to quickly validate UI ideas in real code, and full-stack developers who want to skip tedious boilerplate when building new interfaces. Startups and indie makers use it to ship product quickly without a dedicated frontend team. It's also excellent for learning — seeing how v0 structures components is a practical way to study React and Tailwind CSS patterns.
