v0 is Vercel’s AI app builder. You describe a UI or paste a screenshot, and it generates React components styled with Tailwind and shadcn/ui that you can copy into a real project or deploy straight to Vercel. Of all the ‘prompt-to-app’ tools we tested, v0 produces the cleanest code for developers who already live in the React ecosystem.

How it works#

You type a prompt (“a pricing page with three tiers and a monthly/annual toggle”) or upload an image, and v0 returns a working component with live preview. You can iterate in chat, fork versions, and open the result in your editor or push it to a Vercel project. It leans on shadcn/ui primitives, so the output matches a stack thousands of teams already use.

Strengths#

Output is idiomatic React + Tailwind + shadcn/ui — easy to drop into an existing codebase
Screenshot-to-UI is genuinely useful for rebuilding a reference design
Tight integration with Vercel deploy and Next.js
Version forking lets you explore variations without losing work

Weaknesses#

Best for frontend UI, not full-stack backends or complex data models
Assumes you’re comfortable with React — non-developers will hit a wall
Credits can burn fast on heavy iteration
Generated logic still needs a developer to review and wire up

Pricing#

Free — $0: Limited monthly credits, good for trying it
Premium — ~$20/mo: More credits for regular use
Team — ~$30/user/mo: Shared workspaces and higher limits

Verdict#

If you write React, v0 is the app builder to beat — it saves hours on first-draft UI and the code is clean enough to keep. If you’re a non-technical founder, start with Lovable or Bolt instead.

FAQ#

Q: Does v0 write backend code?

It focuses on frontend React/Next.js UI. It can scaffold routes and simple server actions, but complex backends still need a developer.

Q: Can I use the code commercially?

Yes — the generated code is yours to use in your projects.

Q: Do I need Vercel to use v0?

No. You can copy the code anywhere, though deploy is smoothest on Vercel.
