Replay: The Step-by-Step Guide to Building Landing Pages from Video to Code in 2026

TL;DR: Replay lets you build fully functional landing pages from video recordings, offering a faster, behavior-driven alternative to traditional screenshot-to-code methods.

Replay: The Step-by-Step Guide to Building Landing Pages from Video to Code in 2026#

Building landing pages is a critical part of any successful online strategy. However, traditional methods involving design tools, coding, and iterative testing can be time-consuming and resource-intensive. What if you could simply record a user interacting with a desired landing page experience and instantly generate the code for it? That’s the power of Replay.

Replay leverages the power of video analysis and AI to reconstruct user interfaces, understanding user behavior and intent far beyond what screenshots can offer. This guide will walk you through the process of using Replay to create landing pages from video recordings, saving you time and resources while ensuring a user-centric design.

Understanding Behavior-Driven Reconstruction#

Replay isn't just another screenshot-to-code tool. It employs "Behavior-Driven Reconstruction," meaning it analyzes video to understand what users are trying to achieve, not just what they see. This is crucial for capturing dynamic elements, animations, and complex user flows that screenshots miss entirely.

The Limitations of Screenshot-to-Code#

Screenshot-to-code tools are limited by their static nature. They can generate basic HTML and CSS based on visual elements, but they fail to capture the nuances of user interaction and dynamic behavior.

Replay overcomes these limitations by analyzing the entire video, understanding the sequence of actions, and reconstructing the underlying code to reflect the intended user experience.

Step-by-Step Guide to Building Landing Pages with Replay#

Here's how to build a landing page from a video using Replay:

Step 1: Capture the Desired User Experience#

The first step is to record a video of the desired user experience for your landing page. This video should showcase the key interactions, animations, and overall flow you want to replicate.

💡 Pro Tip: Use a screen recording tool that captures high-quality video and audio. Consider adding voice-over narration to explain the intended functionality.

Step 2: Upload the Video to Replay#

Navigate to the Replay platform and upload the video you recorded. Replay supports various video formats, including MP4, MOV, and WebM.

Step 3: Replay Analyzes the Video#

Once uploaded, Replay's AI engine analyzes the video, identifying UI elements, user interactions, and the overall flow of the landing page. This process can take a few minutes, depending on the length and complexity of the video.

📝 Note: During the analysis phase, Replay uses Gemini to understand the semantic meaning of the elements in the video, enabling it to generate more accurate and context-aware code.

Step 4: Review and Refine the Generated Code#

After the analysis is complete, Replay generates the code for your landing page. You can review the code and make any necessary refinements. Replay provides a user-friendly interface for editing the HTML, CSS, and JavaScript.

typescript
// Example of generated JavaScript code
document.getElementById('submit-button').addEventListener('click', async () => {
  const email = document.getElementById('email-input').value;
  const response = await fetch('/api/submit', {
    method: 'POST',
    body: JSON.stringify({ email }),
    headers: {
      'Content-Type': 'application/json'
    }
  });
  if (response.ok) {
    alert('Thank you for subscribing!');
  } else {
    alert('An error occurred. Please try again.');
  }
});

Step 5: Integrate with Your Tech Stack#

Replay offers seamless integration with popular development tools and platforms, including:

• •Supabase: Easily connect your landing page to a Supabase database for data storage and retrieval.
• •Style Injection: Inject custom CSS styles to fine-tune the appearance of your landing page.
• •Multi-Page Generation: Reconstruct entire websites with multiple pages, maintaining navigation and user flow.

Step 6: Deploy Your Landing Page#

Once you're satisfied with the code, you can deploy your landing page to your preferred hosting provider. Replay provides options for exporting the code as a static HTML file or integrating with platforms like Netlify and Vercel.

Key Features of Replay#

Replay offers a range of features designed to streamline the landing page creation process:

• •Video Input: Analyze landing page experiences directly from video recordings. ✅
• •Behavior-Driven Reconstruction: Understand user intent and recreate dynamic interactions. ✅
• •Multi-Page Generation: Generate code for entire websites with multiple pages. ✅
• •Supabase Integration: Connect your landing page to a Supabase database. ✅
• •Style Injection: Customize the appearance of your landing page with custom CSS. ✅
• •Product Flow Maps: Visualize the user flow and interactions within your landing page.✅

Real-World Use Cases#

Replay can be used in a variety of scenarios:

• •Rapid Prototyping: Quickly create prototypes of landing pages based on competitor analysis videos.
• •A/B Testing: Generate variations of landing pages based on different user interaction patterns.
• •UI/UX Optimization: Identify areas for improvement in existing landing pages by analyzing user behavior videos.
• •Codebase Modernization: Quickly rebuild legacy landing pages by recording user interactions.

Example: Reconstructing a Subscription Form#

Let's say you want to reconstruct a subscription form from a video. The video shows a user entering their email address and clicking the "Subscribe" button. Replay can analyze this video and generate the following HTML code:

html
<form id="subscription-form">
  <label for="email-input">Email Address:</label>
  <input type="email" id="email-input" name="email" placeholder="Enter your email">
  <button type="submit" id="submit-button">Subscribe</button>
</form>

And the corresponding JavaScript code to handle the form submission:

javascript
document.getElementById('subscription-form').addEventListener('submit', async (event) => {
  event.preventDefault(); // Prevent default form submission
  const email = document.getElementById('email-input').value;

  // Basic email validation (you can add more robust validation)
  if (!email.includes('@')) {
    alert('Please enter a valid email address.');
    return;
  }

  try {
    const response = await fetch('/api/subscribe', {
      method: 'POST',
      headers: {
        'Content-Type': 'application/json',
      },
      body: JSON.stringify({ email: email }),
    });

    if (response.ok) {
      alert('Thank you for subscribing!');
      document.getElementById('email-input').value = ''; // Clear the input field
    } else {
      console.error('Subscription failed:', response.status, response.statusText);
      alert('Subscription failed. Please try again later.');
    }
  } catch (error) {
    console.error('Error during subscription:', error);
    alert('An error occurred. Please try again later.');
  }
});

This example demonstrates how Replay can generate functional code based on user interactions in a video.

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 and higher usage limits.

How is Replay different from v0.dev?#

While both tools aim to generate code, Replay differentiates itself by using video as the primary input. This allows Replay to capture dynamic behavior and user intent, resulting in more accurate and functional code. V0.dev typically uses text prompts and templates to generate UI components.

What types of landing pages can I build with Replay?#

You can build a wide variety of landing pages, including:

• •Lead generation pages
• •Product showcase pages
• •Event registration pages
• •Sales pages
• •Coming soon pages

What if the video quality is poor?#

Replay works best with high-quality videos. However, it can still analyze lower-quality videos, although the accuracy of the generated code may be reduced.

⚠️ Warning: Ensure your video is clear and captures all relevant user interactions for optimal results. Blurry video will impact accuracy.

Conclusion#

Replay represents a paradigm shift in landing page development, moving from static design tools and manual coding to a behavior-driven approach powered by video analysis and AI. By capturing the essence of user interaction, Replay empowers developers to create user-centric landing pages more efficiently and effectively.
