v0

Vercel's generative UI tool: describe a screen, get a shadcn/ui implementation.

Preview of v0

What it is

v0 generates React, Tailwind and shadcn/ui interfaces from text prompts and images, with a live preview and iterative editing. It's a fast way to get a first version of a page or component that follows current conventions, which you can then export to your project.

Why it’s here

Very good at conventional product UI, less good at anything with a strong point of view. Use it to get structure quickly, then bring the result into your codebase and apply your own type, colour and spacing.

Best for

  • first drafts of screens
  • shadcn/ui projects
  • beginners
  • prototyping

Can my agent use this?

Agent good agent friendliness

Partly. v0 is itself an agent; the output can be added to a project with the shadcn CLI or exported. Give the result to your main coding agent to integrate and restyle.

Good: Publicly accessible and useful to reference, but the agent will need to interpret it rather than install it.
