Replay: The Fastest Way to Get Your UI Prototypes into Production from Video in 2026

TL;DR: Replay uses video analysis and AI to rapidly generate working UI prototypes from screen recordings, understanding user intent and behavior far beyond simple screenshot-to-code conversion.

The year is 2026. Design sprints are still a thing, but the handoff from design to development has been revolutionized. Forget static mockups and endless spec documents. The fastest way to turn a UI prototype into production-ready code? Video. And the tool making it happen is Replay.

The Problem: Static Designs Don't Tell the Whole Story#

We've all been there. A beautiful design lands in your inbox. It looks pixel-perfect. But as you start building, questions arise:

• •How does the user really navigate this flow?
• •What happens when they click that button?
• •Are there subtle animations or transitions missing from the spec?

Traditional design tools give you a snapshot, but they miss the crucial element: behavior. This gap leads to wasted time, miscommunication, and ultimately, a product that doesn't quite match the original vision.

The Solution: Behavior-Driven Reconstruction with Replay#

Replay takes a fundamentally different approach. Instead of relying on static images, Replay analyzes video recordings of user interactions. It leverages advanced AI, powered by Gemini, to understand user intent and reconstruct a fully functional UI. This "Behavior-Driven Reconstruction" means you get more than just a visual representation; you get a working prototype that accurately reflects the intended user experience.

How Replay Works: Video as the Source of Truth#

Replay treats the video recording as the single source of truth. It analyzes:

• •Mouse movements and clicks
• •Keyboard inputs
• •Page transitions and animations
• •Data inputs and form submissions

Based on this analysis, Replay generates clean, maintainable code that replicates the observed behavior.

Key Features of Replay#

Replay isn't just another screenshot-to-code tool. It offers a suite of powerful features designed to streamline the UI development process:

• •Multi-Page Generation: Replay can handle complex, multi-page flows, generating code for entire user journeys.
• •Supabase Integration: Seamlessly connect your generated UI to your Supabase backend for rapid prototyping and data integration.
• •Style Injection: Apply your existing CSS styles or generate new styles based on the video's visual appearance.
• •Product Flow Maps: Automatically generate visual diagrams of user flows based on the video analysis.

Replay vs. The Alternatives: A Clear Advantage#

Let's compare Replay to some other popular UI generation tools:

As you can see, Replay uniquely combines ease of use with powerful behavior analysis and code generation capabilities.

Getting Started with Replay: A Step-by-Step Guide#

Here's how to quickly generate a UI prototype using Replay:

Step 1: Record Your UI Flow#

Use any screen recording tool (e.g., Loom, QuickTime) to record a video of your desired UI flow. Be sure to clearly demonstrate all interactions and transitions.

💡 Pro Tip: Speak clearly while recording to provide additional context that Replay can leverage.

Step 2: Upload Your Video to Replay#

Navigate to the Replay web application and upload your video file. Replay will automatically begin analyzing the video and reconstructing the UI.

Step 3: Review and Refine the Generated Code#

Once the analysis is complete, Replay will present you with the generated code. You can review and refine the code as needed, making adjustments to styles, layouts, and functionality.

Step 4: Integrate with Your Project#

Download the generated code and integrate it into your existing project. Replay supports a variety of frameworks and libraries, including React, Vue.js, and Angular.

Example: Generating a React Component with Replay#

Let's say you've recorded a video of a user interacting with a simple form. Replay can generate a React component like this:

typescript
// Generated by Replay
import React, { useState } from 'react';

const MyForm = () => {
  const [name, setName] = useState('');
  const [email, setEmail] = useState('');

  const handleSubmit = async (e: React.FormEvent) => {
    e.preventDefault();
    // Simulate API call
    try {
      const response = await fetch('/api/submit', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
        },
        body: JSON.stringify({ name, email }),
      });
      const data = await response.json();
      console.log('Success:', data);
      alert('Form submitted successfully!');
    } catch (error) {
      console.error('Error:', error);
      alert('Form submission failed.');
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label htmlFor="name">Name:</label>
        <input
          type="text"
          id="name"
          value={name}
          onChange={(e) => setName(e.target.value)}
        />
      </div>
      <div>
        <label htmlFor="email">Email:</label>
        <input
          type="email"
          id="email"
          value={email}
          onChange={(e) => setEmail(e.target.value)}
        />
      </div>
      <button type="submit">Submit</button>
    </form>
  );
};

export default MyForm;

This code is not just a static representation of the form; it's a fully functional React component that you can immediately integrate into your application.

⚠️ Warning: While Replay strives for accuracy, always review the generated code to ensure it meets your specific requirements and security standards.

Benefits of Using Replay#

• •Faster Prototyping: Quickly generate working UI prototypes from video recordings.
• •Improved Communication: Bridge the gap between design and development with behavior-driven reconstruction.
• •Reduced Development Time: Automate the tedious task of manually coding UI elements.
• •Enhanced User Experience: Ensure that your UI accurately reflects the intended user experience.

Frequently Asked Questions#

Is Replay free to use?#

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

How is Replay different from v0.dev?#

While v0.dev generates UI components based on text prompts, Replay analyzes video recordings to understand user behavior and generate more accurate and context-aware code. Replay focuses on reconstructing existing or intended workflows, not just creating individual components. Replay also supports multi-page flows, which is a key differentiator.

What frameworks and libraries does Replay support?#

Replay currently supports React, Vue.js, and Angular. Support for additional frameworks is planned for future releases.

How secure is Replay?#

Replay uses industry-standard security measures to protect your data. Video recordings are processed securely and are not stored indefinitely.

Can I customize the generated code?#

Yes, the generated code is fully customizable. You can modify the code to meet your specific requirements and integrate it into your existing project.
