Mobbin vs 21st.dev vs Monet: Which Design Reference Site Should You Use?

You've found the perfect design inspiration. A beautiful hero section, an elegant pricing table, a conversion-optimized CTA. Now comes the hard part: how do you actually build it?

This gap between inspiration and implementation is the daily struggle for developers and designers alike. In this guide, we'll compare three leading platforms—Mobbin, 21st.dev, and Monet—each solving this problem in fundamentally different ways.

The Problem: From Inspiration to Implementation

We've all been there. You spend hours on design reference sites, collecting screenshots of beautiful interfaces. Your Figma board is full of inspiration. But when you sit down to code, you're staring at a blank page.tsx file wondering how to recreate what you saw.

The traditional workflow looks like this:

1. Find inspiration (hours of browsing)
2. Analyze the design (studying spacing, colors, typography)
3. Recreate from scratch (trial and error)
4. Debug responsiveness (more trial and error)
5. Polish and refine (endless tweaking)

Each platform we'll discuss today attacks a different part of this workflow. Understanding their strengths will help you choose the right tool—or combination of tools—for your needs.

Mobbin: The Inspiration Library

Mobbin is the gold standard for design research. Think of it as a massive, searchable museum of the world's best mobile and web interfaces.

What Mobbin Offers

Mobbin curates thousands of screenshots from popular apps like Airbnb, Stripe, Linear, and Notion. Every screen is meticulously tagged and categorized, making it easy to find exactly what you're looking for.

Key features include:

• Extensive filtering: Search by screen type (onboarding, checkout, settings), UI pattern, or specific app
• Flow documentation: See entire user journeys, not just isolated screens
• Figma integration: Export screens directly to your design files
• Regular updates: New apps and screens added continuously

Mobbin's Strengths

Mobbin excels at answering the question: "How did successful products solve this design problem?"

Whether you're researching how top apps handle empty states, designing a notification center, or studying checkout flows, Mobbin has real-world examples from products with millions of users.

Mobbin's Limitations

Here's the catch: Mobbin gives you screenshots, not code.

You'll see beautiful designs, but translating them into working React components is entirely up to you. For developers without design training, this gap can feel insurmountable.

Ideal Use Cases for Mobbin

• UX research and competitive analysis
• Design system exploration
• Stakeholder presentations ("Here's how Stripe does it")
• Early-stage ideation before implementation

21st.dev: AI-Ready Components

21st.dev takes a different approach. Instead of showing you what to build, it gives you tools to build it faster—especially if you're working with AI assistants.

What 21st.dev Offers

21st.dev is a community-driven catalog of UI components with a twist: each component comes with AI-ready prompts you can paste directly into ChatGPT, Claude, or Cursor.

Key features include:

• Copy-paste AI prompts: Pre-written prompts that generate consistent components
• Community contributions: Growing library of user-submitted designs
• Framework agnostic: Components for React, Vue, and other frameworks
• Open source focus: Many components are freely available

21st.dev's Strengths

21st.dev bridges the gap between inspiration and AI-assisted development. Instead of describing components from scratch, you copy a battle-tested prompt that produces reliable results.

This is particularly valuable in the vibe coding era, where developers increasingly rely on AI to generate UI code.

21st.dev's Limitations

Quality varies significantly. Since it's community-driven, you'll find everything from polished, production-ready components to rough prototypes. The AI-generated output also requires review and often needs refinement.

Ideal Use Cases for 21st.dev

• Rapid prototyping with AI tools
• Learning component patterns and structures
• Starting points for custom implementations
• Developers comfortable reviewing AI output

Monet: Production-Ready Landing Page Components

Monet approaches the problem from the opposite direction. Instead of generating new code each time, Monet provides a curated library of pre-built, validated components ready for immediate use.

What Monet Offers

Monet is a premium collection of React UI components specifically designed for landing pages. Every component is built with Next.js, TypeScript, and Tailwind CSS—and works immediately with copy-paste.

Key features include:

• Copy-paste workflow: No npm packages, no version conflicts
• Landing page focus: Hero sections, features, pricing, testimonials, CTAs
• Production quality: Every component is tested in real projects
• MCP integration: AI assistants can search and recommend components directly

The Copy-Paste Advantage

Unlike traditional component libraries that require installation and configuration, Monet components are self-contained. Copy the code, paste it into your project, and it works.

// Example: A Monet Hero Section
export function HeroGradient() {
  return (
    <section className="relative overflow-hidden bg-gradient-to-br from-purple-900 via-purple-800 to-indigo-900 px-6 py-32">
      <div className="mx-auto max-w-4xl text-center">
        <h1 className="text-5xl font-bold tracking-tight text-white sm:text-7xl">
          Build beautiful landing pages
        </h1>
        <p className="mt-6 text-lg leading-8 text-purple-100">
          Premium React components for modern web applications
        </p>
      </div>
    </section>
  );
}

You own the code. Customize it freely without worrying about upstream changes or dependency conflicts.

MCP Integration for AI Workflows

Monet's MCP (Model Context Protocol) integration sets it apart. Connect Monet MCP to Claude Desktop or Claude Code, and your AI assistant can:

• Search the component library based on your requirements
• Recommend suitable components for your use case
• Provide the exact code you need

# Add Monet MCP to Claude Code
claude mcp add monet -- npx -y @anthropic/monet-mcp

This creates a workflow where AI doesn't generate components from scratch (with unpredictable quality) but instead recommends proven, tested solutions.

Monet's Strengths

• Consistency: Same component, same quality, every time
• Speed: No generation wait times or AI output review
• Reliability: Components tested across real production sites
• Customization: Full code ownership for complete control

Monet's Limitations

Monet focuses specifically on landing page components. For app-specific UI (dashboards, data tables, complex forms), you'll need additional resources.

Ideal Use Cases for Monet

• Building marketing sites and landing pages
• Rapid iteration on startup homepages
• Teams wanting consistent, validated components
• Developers using AI assistants who want reliable recommendations
