v0 by Vercel

v0 by Vercel is an AI interface generator that turns prompts, sketches or screenshots into React components styled with Tailwind CSS. It returns clean, copy-ready code alongside a live preview, so front-end work starts from a real component instead of a blank file. Front-end developers, designers and product teams use it to move from idea to interface in minutes.

Key features

• Prompt-to-UI generation producing React and Tailwind code you can paste straight into a project.
• Image and screenshot input for recreating an existing design or a rough sketch.
• Multiple variations per prompt, with iterative refinement through follow-up messages.
• Live preview beside the generated code, including responsive behaviour.
• shadcn/ui component conventions that match a widely used design-system setup.
• Direct deployment and project handoff through the wider Vercel platform.

Who it is for

• Front-end developers who want a fast, well-structured starting point for new screens.
• Designers who need working code to communicate an idea to engineering.
• Full-stack builders assembling admin panels, dashboards and marketing pages.
• Teams standardising on React, Tailwind and component-library patterns.

Pricing

v0 offers a free tier with a monthly credit allowance, with paid plans for higher limits and team use. Current pricing is published on the v0 website.

Why people choose v0 by Vercel

People looking for the best AI tool to generate React components choose v0 because the output is idiomatic, readable code rather than an image or an export. Being able to describe a screen, see it rendered and take the code into a real project removes the slowest part of front-end work, and the Tailwind and shadcn conventions mean the result usually fits an existing codebase with little rework.
