v0.app

Overview

• Tool name: v0.app
• Developer: Vercel
• Official website: https://v0.app/
• Category: AI Coding Tools

v0 is Vercel's AI app builder. You describe an interface — or paste a screenshot or a Figma frame — and it returns working React code styled with Tailwind CSS and shadcn/ui, alongside a live preview you can iterate on in chat. It began in 2023 as a text-to-component experiment and was rebuilt in February 2026 into a fuller development environment with Git integration, an in-browser code editor, database connections, and one-click deployment to Vercel. The stack opinion is deliberate: if you are already on Next.js and Tailwind, v0 produces output you can actually ship.

Key Uses

• Generate React and Next.js interfaces from a prompt: Describe a pricing page, a dashboard, or a settings screen and get real components with Tailwind classes and shadcn/ui patterns rather than a mockup image.
• Turn screenshots and Figma frames into code: Paste a design and v0 reconstructs it, preserving spacing, colour values, and hierarchy — the fastest way to close the gap between a mockup and a working page.
• Prototype before committing engineering time: Product teams can click through a functional prototype in an afternoon and validate an idea before a sprint is spent on it.
• Edit visually without touching code: Design Mode lets non-developers select elements and adjust styling and layout directly, which removes the round trip through an engineer for small changes.
• Ship straight to a URL: Projects deploy to Vercel in one click with preview URLs for every change, and sync to GitHub when the code needs to live in a repository.

Pricing

• Free: a small monthly credit allowance plus daily message limits. Enough for a handful of generations — roughly enough to evaluate the output quality, not to build a project.
• Premium / Plus: around $20 to $30 per user per month, with a larger monthly credit allowance, higher upload limits, Figma import, and API access.
• Team: roughly $30 per user per month with shared credits and centralized billing.
• Business: about $100 per user per month, adding higher limits, org controls, and training opt-out by default.
• Enterprise: custom pricing with SSO, priority performance, and support.

v0 meters by token, not by message, and each conversation carries its context in the input — so a short prompt on a large project can cost more than it looks. Credits do not roll over. Vercel hosting for production is billed separately. Check v0.app/pricing for current figures.

Who It Is For

• Next.js and Vercel-first teams: The output stack matches what they already run, so generated code drops straight into the project.
• Designers producing prototypes: Figma and screenshot import plus Design Mode means a designer can get to something clickable without an engineer.
• Product managers validating ideas: A working prototype in an afternoon is a better validation artifact than a static mockup.
• Startups without frontend capacity: A landing page, an admin view, and basic auth can be scaffolded before the first frontend hire.

How to Use v0.app

1. Go to v0.app and sign in with a Vercel account.

2. Start a new project by describing the interface, or paste a screenshot or Figma link to work from an existing design.

3. Review the live preview. Iterate in chat — describe what to change rather than rewriting the whole prompt.

4. Switch to Design Mode to adjust spacing, colour, and layout by selecting elements directly.

5. Open the built-in editor to inspect or edit the generated code when chat is not precise enough.

6. Connect a database such as Supabase if the app needs real data rather than placeholder content.

7. Sync the project to GitHub so the code lives in version control.

8. Deploy to Vercel in one click and check the result on the preview URL before pointing a domain at it.

Tips for Best Results

• Specify the stack in your first prompt. Naming Next.js, Tailwind, and shadcn/ui up front keeps output consistent across iterations.
• Work in small iterations. Large multi-screen requests degrade in quality. Generate one screen or component at a time and compose them.
• Watch your credits from the first project. Context is resent with every message, so long threads burn credits faster than newcomers expect.
• Review dependencies after generating. The model occasionally imports shadcn/ui components that are not installed in your project, which breaks the build.
• Treat backend output as a draft. UI generation is strong; API wiring, auth, and permissions still need a developer to review.
• Use Business or Enterprise for sensitive work. Lower tiers may use your data for training by default.

Limitations

• The free tier's credit allowance is small — a couple of small projects at most before you hit the wall.
• Credit consumption is opaque. A single complex generation can consume a meaningful share of a monthly allowance, and unused credits do not roll over.
• It is locked to the React and Next.js stack. There is no Vue, Svelte, or non-JavaScript output.
• Backend generation is materially weaker than UI generation — APIs, database wiring, and auth need real engineering review.
• Quality drops on complex multi-screen apps. It is strongest on individual components and pages.
• Vercel hosting is a separate cost from the v0 subscription, which teams routinely forget when budgeting.

Frequently Asked Questions

What is v0?

v0 is Vercel's AI app builder. It turns natural-language prompts, screenshots, and Figma frames into working React and Next.js code styled with Tailwind CSS and shadcn/ui, which you can edit, sync to GitHub, or deploy.

Is v0 free?

There is a free tier with a small monthly credit allowance and daily message limits. It is enough to evaluate output quality, not to build and ship a project.

How much does v0 cost?

Paid plans run roughly from $20 per month to about $100 per user per month, with Team around $30 per user and Enterprise custom. Credits are metered by token. Check v0.app/pricing for current figures.

Is the generated code production-ready?

For UI, largely yes — it follows React and TypeScript conventions with accessibility attributes and responsive behaviour. Backend logic, permissions, and data handling still need a developer's review.

Does v0 support frameworks other than React?

No. Output targets React, Next.js, Tailwind, and shadcn/ui specifically. Teams on Vue, Svelte, or other stacks should look elsewhere.

Does v0 have an API?

Yes. There is a platform API for generating projects programmatically and a model API for calling v0's coding models directly.

How is v0 different from Lovable or Bolt?

v0 produces higher-quality UI code for the Next.js and Vercel ecosystem. Lovable and Bolt go further on complete full-stack apps for non-developers, but professional teams more often keep v0's output.
