How to Recreate a Multi-Page Website from Video to Next.js with Replay in 2026

TL;DR: Replay uses video analysis powered by Gemini to reconstruct a fully functional, multi-page Next.js website from a simple screen recording, offering a behavior-driven approach to code generation.

Recreating Multi-Page Websites: The Video-to-Code Revolution#

The dream of turning design concepts into functional code has been around for ages. While screenshot-to-code tools offer a glimpse into this future, they often fall short of capturing the intent behind user interactions and creating truly dynamic, multi-page applications. Imagine trying to build an e-commerce site from screenshots alone – you'd miss critical user flows, form submissions, and dynamic state changes. That's where video-to-code engines come in.

Enter Replay, a game-changing tool that leverages video analysis and the power of Gemini to reconstruct working UI, complete with multi-page navigation and dynamic functionality. Instead of simply rendering what it sees, Replay understands how users interact with the interface, enabling a behavior-driven approach to code generation.

The Problem with Static Approaches#

Traditional methods, including screenshot-to-code tools and static design imports, often struggle with:

• •Lack of Context: They can't capture the dynamic behavior of a website, leading to incomplete or inaccurate code.
• •Multi-Page Complexity: Handling navigation and data flow between pages is a major challenge.
• •User Intent: They fail to understand the "why" behind user actions, resulting in rigid and inflexible code.
• •Maintenance Overhead: The generated code often requires significant manual adjustments and debugging.

Replay: Behavior-Driven Reconstruction in Action#

Replay addresses these limitations by analyzing video recordings of website interactions. This allows it to understand user flows, form submissions, and dynamic state changes, resulting in more accurate and functional code generation.

Here's a breakdown of how Replay differs from other code generation tools:

Building a Next.js Website from Video: A Step-by-Step Guide#

Let's walk through the process of recreating a multi-page website using Replay and Next.js. In this example, we'll recreate a simple blog with two pages: a homepage displaying a list of blog posts and a detail page for each post.

Step 1: Record the User Flow#

First, record a video of you navigating the existing website. Be sure to capture all the key interactions, including:

• •Navigating between the homepage and individual blog post pages.
• •Scrolling through the content.
• •Interacting with any interactive elements (e.g., liking a post).

💡 Pro Tip: Speak clearly while recording, describing what you are doing. This helps Replay's AI understand the intent behind your actions.

Step 2: Upload the Video to Replay#

Upload the recorded video to Replay. The platform will automatically analyze the video and begin reconstructing the UI. This process can take a few minutes, depending on the length and complexity of the video.

Step 3: Review and Refine the Generated Code#

Once the reconstruction is complete, Replay will present you with the generated Next.js code. This code will include:

• •React components for each page.
• •Navigation logic to handle routing between pages.
• •Data fetching logic to retrieve blog post data (optionally integrated with Supabase).
• •Basic styling.

typescript
// Example: Generated HomePage component in Next.js
import Link from 'next/link';

const HomePage = ({ posts }) => {
  return (
    <div>
      <h1>Blog Posts</h1>
      <ul>
        {posts.map((post) => (
          <li key={post.id}>
            <Link href={`/posts/${post.id}`}>
              <a>{post.title}</a>
            </Link>
          </li>
        ))}
      </ul>
    </div>
  );
};

export default HomePage;

Step 4: Integrate with Supabase (Optional)#

Replay offers seamless integration with Supabase, allowing you to automatically connect your generated code to a Supabase database. This is particularly useful for dynamic content like blog posts.

To enable Supabase integration:

1. •Provide your Supabase project URL and API key to Replay.
2. •Replay will automatically generate the necessary data models and API endpoints.
3. •The generated Next.js code will include data fetching logic that uses the Supabase API.

Step 5: Inject Custom Styles#

Replay also allows you to inject custom styles into the generated code. You can use CSS, Tailwind CSS, or any other styling framework.

To inject styles:

1. •Provide your CSS or Tailwind CSS code to Replay.
2. •Replay will automatically apply the styles to the generated components.

📝 Note: Replay intelligently attempts to map your styles to the generated components, but you may need to make minor adjustments to ensure perfect visual fidelity.

Step 6: Product Flow Maps#

Replay automatically generates a product flow map, visualizing the user's journey through the website. This map helps you understand the overall structure of the website and identify potential areas for improvement.

Step 7: Deploy and Iterate#

Once you are satisfied with the generated code, you can deploy it to your favorite hosting platform (e.g., Vercel, Netlify). From there, you can continue to refine the code and add new features.

Advanced Techniques and Considerations#

• •Handling Complex Interactions: For websites with complex interactions (e.g., drag-and-drop, animations), it may be necessary to provide more detailed video recordings or manually adjust the generated code.
• •State Management: Replay can infer basic state management logic from video recordings, but for more complex applications, you may need to integrate a state management library like Redux or Zustand.
• •Accessibility: While Replay generates functional code, it's important to ensure that the generated website is accessible to users with disabilities. This may require manual adjustments to ARIA attributes and other accessibility features.

⚠️ Warning: The generated code is a starting point, not a finished product. You'll likely need to make adjustments to fine-tune the functionality and aesthetics of the website.

Code Example: Fetching Data from Supabase#

Here's an example of how to fetch blog post data from a Supabase database using the generated code:

typescript
// Example: Fetching blog posts from Supabase
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = process.env.NEXT_PUBLIC_SUPABASE_URL;
const supabaseKey = process.env.NEXT_PUBLIC_SUPABASE_ANON_KEY;
const supabase = createClient(supabaseUrl, supabaseKey);

export const getPosts = async () => {
  const { data, error } = await supabase
    .from('posts')
    .select('*')
    .order('created_at', { ascending: false });

  if (error) {
    console.error('Error fetching posts:', error);
    return [];
  }

  return data;
};

Benefits of Using Replay#

• •Faster Development: Replay significantly reduces the time and effort required to recreate existing websites or build new prototypes.
• •Improved Accuracy: By analyzing video recordings, Replay captures user intent and dynamic behavior, resulting in more accurate and functional code.
• •Enhanced Collaboration: Replay facilitates collaboration between designers and developers by providing a common language (video) for communicating design intent.
• •Reduced Costs: By automating the code generation process, Replay helps reduce development costs.
• •Behavior-Driven Development: Replay encourages a behavior-driven approach to development, ensuring that the website meets the needs of its users.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited features and usage. Paid plans are available for users who require more advanced features or higher usage limits.

How is Replay different from v0.dev?#

While both tools aim to accelerate UI development, Replay focuses on reconstructing existing UIs from video, capturing user behavior and intent. v0.dev generates UI components based on text prompts. Replay provides a behavior-driven approach, whereas v0.dev offers a generative AI approach.

What kind of videos work best with Replay?#

Clear, well-lit videos with minimal distractions generally produce the best results. Speaking clearly and deliberately while recording helps Replay understand the user's intent.

What frameworks are supported by Replay?#

Currently, Replay primarily supports Next.js. Support for other frameworks, like React and Vue.js, is planned for future releases.

Can I use Replay to recreate complex animations?#

Replay can capture basic animations, but complex animations may require manual adjustments to the generated code.
