v0.dev: Generate Production-Ready React Components from Text Prompts

Vercel released v0.dev. Type what you want, get React components. “Create a pricing page with 3 tiers.” Boom - complete component with Tailwind CSS.

I built 5 landing pages in 2 hours. Here’s what works and what doesn’t.

What is v0.dev?

Text → React Component generator.

Input: “Create a hero section with gradient background” Output: Complete React + Tailwind component, ready to use

Getting Started

# Visit v0.dev
# Sign in with GitHub
# Start prompting

Free tier: 200 credits/month Pro: $20/month unlimited

Example 1: Hero Section

Prompt:

Create a modern hero section with:
- Gradient background (purple to blue)
- Large heading and subheading
- Two CTA buttons (primary and secondary)
- Responsive design

Generated Code:

export default function Hero() {
  return (
    <div className="relative overflow-hidden bg-gradient-to-br from-purple-600 to-blue-600">
      <div className="mx-auto max-w-7xl px-6 py-24 sm:py-32 lg:px-8">
        <div className="mx-auto max-w-2xl text-center">
          <h1 className="text-4xl font-bold tracking-tight text-white sm:text-6xl">
            Build faster with AI-powered tools
          </h1>
          <p className="mt-6 text-lg leading-8 text-gray-100">
            Transform your ideas into production-ready applications in minutes,
            not hours. Our AI-powered platform handles the complexity.
          </p>
          <div className="mt-10 flex items-center justify-center gap-x-6">
            <a
              href="#"
              className="rounded-md bg-white px-3.5 py-2.5 text-sm font-semibold text-purple-600 shadow-sm hover:bg-gray-100 focus-visible:outline focus-visible:outline-2 focus-visible:outline-offset-2 focus-visible:outline-white"
            >
              Get started
            </a>
            <a
              href="#"
              className="text-sm font-semibold leading-6 text-white"
            >
              Learn more <span aria-hidden="true">→</span>
            </a>
          </div>
        </div>
      </div>
    </div>
  );
}

Result: Perfect! Copy-paste ready.

Example 2: Pricing Table

Prompt:

Create a pricing table with 3 tiers:
- Free: $0, 10 projects, basic support
- Pro: $29, unlimited projects, priority support, advanced features
- Enterprise: Custom pricing, dedicated support, SLA

Include:
- Popular badge on Pro tier
- Feature comparison
- CTA buttons
- Dark mode support

Generated Code (simplified):

export default function Pricing() {
  const tiers = [
    {
      name: 'Free',
      price: '$0',
      features: ['10 projects', 'Basic support', 'Community access'],
      cta: 'Start free',
      popular: false,
    },
    {
      name: 'Pro',
      price: '$29',
      features: ['Unlimited projects', 'Priority support', 'Advanced features', 'API access'],
      cta: 'Start trial',
      popular: true,
    },
    {
      name: 'Enterprise',
      price: 'Custom',
      features: ['Dedicated support', 'SLA guarantee', 'Custom integrations', 'Training'],
      cta: 'Contact sales',
      popular: false,
    },
  ];

  return (

        </div>
        <div className="mt-16 grid grid-cols-1 gap-8 sm:grid-cols-2 lg:grid-cols-3">
          {tiers.map((tier) => (
            <div

              className={`relative rounded-2xl border ${
                tier.popular
                  ? 'border-purple-600 shadow-lg'

              )}
              <h3 className="text-lg font-semibold text-gray-900 dark:text-white">

                {tier.price !== 'Custom' && (
                  <span className="text-sm font-semibold text-gray-600 dark:text-gray-400">

                )}
              </p>
              <ul className="mt-8 space-y-3">
                {tier.features.map((feature) => (

          ))}
        </div>
      </div>
    </div>
  );
}

Result: Production-ready! Dark mode included.

Example 3: Dashboard Layout

Prompt:

Create a dashboard layout with:
- Sidebar navigation (collapsible)
- Top header with user menu
- Main content area with stats cards
- Responsive (mobile: bottom nav)

Generated complete dashboard with:

Sidebar component
Header component
Stats cards
Mobile navigation
All responsive

Time: 2 minutes vs 2 hours manual coding.

Real Project: Landing Page

Built complete landing page:

Sections needed:

Hero
Features (3 columns)
Pricing
Testimonials
FAQ
Footer

Process:

Prompt 1: "Create hero section..."
→ Copy component

Prompt 2: "Create features section with 3 columns..."
→ Copy component

Prompt 3: "Create pricing table..."
→ Copy component

... repeat for all sections

Assembly:

// app/page.tsx
import Hero from '@/components/Hero';
import Features from '@/components/Features';
import Pricing from '@/components/Pricing';
import Testimonials from '@/components/Testimonials';
import FAQ from '@/components/FAQ';
import Footer from '@/components/Footer';

export default function Home() {
  return (
    <main>
      <Hero />
      <Features />
      <Pricing />
      <Testimonials />
      <FAQ />
      <Footer />
    </main>
  );
}

Time: 2 hours (vs 2 days manual)

Customization

Generated code is editable:

Original:

<h1 className="text-4xl font-bold">
  Build faster with AI
</h1>

Customized:

<h1 className="text-4xl font-bold">
  {title} {/* Make it dynamic */}
</h1>

Easy to modify!

Iteration

Refine with follow-up prompts:

Initial: "Create a contact form"
→ Basic form generated

Follow-up: "Add validation and error messages"
→ Form with validation

Follow-up: "Add success state and loading spinner"
→ Complete form with all states

v0 remembers context!

Comparison with Manual Coding

Task: Create pricing page

Aspect	Manual	v0.dev	Winner
Time	4 hours	10 min	v0
Code quality	8/10	9/10	v0
Responsiveness	Manual work	Built-in	v0
Dark mode	Extra work	Built-in	v0
Accessibility	Often missed	Included	v0
Customization	Full control	90% control	Manual

Limitations

1. Not Perfect for Complex Logic:

// v0 is great for UI
<button onClick={handleClick}>Click me</button>

// But you write the logic
const handleClick = () => {
  // Your business logic here
};

2. Requires Tailwind Knowledge:

Generated code uses Tailwind. Need to understand it for customization.

3. Sometimes Over-engineered:

// v0 might generate
<div className="flex items-center justify-center min-h-screen bg-gradient-to-br from-purple-600 via-pink-600 to-blue-600">

// When you just need
<div className="flex items-center justify-center min-h-screen bg-purple-600">

4. Limited Component Libraries:

Generates plain React + Tailwind. If you need shadcn/ui or MUI, requires adaptation.

Best Practices

1. Be Specific:

❌ “Create a form” ✅ “Create a contact form with name, email, message fields, validation, and submit button”

2. Iterate:

Start simple, add features:

1. "Create basic card"
2. "Add hover effect"
3. "Add image and badge"
4. "Make it responsive"

3. Review Generated Code:

Check for:

Accessibility (aria labels)
Performance (unnecessary re-renders)
Security (XSS in user input)

4. Extract Reusable Components:

// v0 generates inline
<button className="rounded-md bg-purple-600...">
  Click me
</button>

// Extract to reusable component
<Button variant="primary">Click me</Button>

Integration with Existing Projects

# 1. Generate component in v0.dev
# 2. Copy code
# 3. Paste into your project

# components/Hero.tsx
export default function Hero() {
  // v0 generated code
}

# app/page.tsx
import Hero from '@/components/Hero';

export default function Home() {
  return <Hero />;
}

Works with:

Next.js
Create React App
Vite
Any React project

Cost Analysis

Free Tier:

Unlimited generations
Priority support
Worth it for professionals

ROI:

Saves 10+ hours/month
At $100/hour = $1,000 value
ROI: 5,000%

Real Results

Built 5 landing pages in 2 hours:

Before v0.dev:

Time per page: 2 days
Total: 10 days
Cost: $8,000 (at $100/hour)

With v0.dev:

Time per page: 24 minutes
Total: 2 hours
Cost: $200 + $20 (v0 subscription)

Savings: $7,780 and 78 hours

Lessons Learned

Great for prototyping - Rapid iteration
Production-ready code - High quality output
Saves massive time - 90% faster
Still need React knowledge - For customization
Best for UI, not logic - Business logic is yours

Conclusion

v0.dev is a game-changer for frontend development. Not a replacement for developers, but a massive productivity boost.

Best for:

Landing pages
Marketing sites
Dashboards
UI prototypes

Not ideal for:

Complex state management
Custom animations
Unique designs

Key takeaways:

90% faster UI development
Production-ready code
Built-in responsiveness and dark mode
Requires Tailwind knowledge
Massive ROI ($20/month → $1000/month value)

Try v0.dev. It will change how you build UIs.
