v0
Prompt-to-UI generator that outputs real React and Tailwind components.
v0 turns a description or screenshot into shadcn/ui-flavoured React with Tailwind classes. Because it emits idiomatic code rather than an opaque export, the output survives contact with a real codebase.
Best used for the first 70% of a screen — layout, states, responsive scaffolding — then finished by hand. Treat generated design tokens carefully; they rarely match an existing design system.
What it's genuinely good at
- Outputs clean React + Tailwind you can actually keep
- Screenshot-to-UI works surprisingly well
- Iterating on a generated screen is fast
- Great for portfolio and hackathon speed
Where it falls apart
- Generated styles ignore your existing design tokens
- Accessibility needs a manual pass
- Credit consumption adds up quickly
Alternatives to v0
Who should use v0
- Hackathon teams needing a UI in an hour
- Developers who dislike writing first-draft markup
- Portfolio projects that need to look designed
What it costs
Free monthly credits; paid plans from about $20/month scale credits with usage.
Frequently asked
Can I use v0 output in production?
Yes, but review accessibility, responsive behaviour and token usage before merging.
Does it work with my design system?
Partially. It defaults to shadcn/ui conventions; mapping to a custom system is manual work.
