Replay: The Only Way to Convert UI from Figma Video to Code (2026)

TL;DR: Replay leverages video analysis with Gemini to reconstruct fully functional UI code from screen recordings, unlike traditional screenshot-to-code tools that lack behavioral understanding.

The year is 2026. Screenshot-to-code tools are relics of the past. They offer a superficial representation of a UI, but fail to capture the intent behind user interactions. If you want to reconstruct a real, working UI from a Figma prototype video, there's only one solution: Replay.

The Problem with Screenshot-to-Code#

Imagine handing a developer a stack of screenshots and asking them to build an entire application. They'd be missing critical information:

• •How does the user navigate?
• •What data is being entered?
• •What are the dynamic states of each component?

Screenshot-to-code tools only provide a static image, leading to:

• •Incomplete and buggy UI
• •Manual rework to add interactivity
• •Massive development time wasted on reverse-engineering

Replay: Behavior-Driven Reconstruction#

Replay takes a fundamentally different approach. Instead of relying on static images, it analyzes video of user interactions. Think of it as "Behavior-Driven Reconstruction." This allows Replay to understand:

• •User flows and navigation patterns
• •Data input and validation
• •Component state changes and animations

Replay uses the power of Gemini to interpret these behaviors and generate clean, functional code that mirrors the original UI.

How Replay Works: The Technical Deep Dive#

1. •Video Analysis: Replay ingests a screen recording of a user interacting with a UI prototype (e.g., a Figma prototype demo).
2. •Behavioral Modeling: Replay's AI engine, powered by Gemini, analyzes the video frame-by-frame to identify user actions, data inputs, and UI state transitions.
3. •Code Generation: Based on the behavioral model, Replay generates clean, production-ready code (React, Vue, Angular, etc.).
4. •Integration: Replay seamlessly integrates with popular tools like Supabase for backend functionality and allows style injection for complete customization.

Key Features of Replay#

• •Multi-Page Generation: Replay can reconstruct entire multi-page applications from a single video recording.
• •Supabase Integration: Automatically connect your UI to a Supabase backend with pre-configured data models and API endpoints.
• •Style Injection: Customize the look and feel of your generated UI with CSS or Tailwind CSS.
• •Product Flow Maps: Visualize user flows and identify potential bottlenecks in your application.
• •Video as Source of Truth: Replay uses the video recording as the single source of truth, ensuring accurate and consistent code generation.

Replay vs. The Alternatives#

Let's compare Replay to other code generation tools:

As you can see, Replay is the only solution that truly understands user behavior and generates complete, functional code from video recordings.

Building a UI with Replay: A Step-by-Step Guide#

Let's walk through a practical example of how to use Replay to reconstruct a simple e-commerce product listing page from a Figma prototype video.

Step 1: Record Your Figma Prototype#

Create a screen recording of yourself interacting with your Figma prototype. Make sure to demonstrate all the key user flows, such as:

• •Scrolling through the product list
• •Clicking on a product to view details
• •Adding a product to the cart

💡 Pro Tip: Speak clearly and deliberately during the recording to help Replay accurately interpret your actions.

Step 2: Upload Your Video to Replay#

Navigate to the Replay web interface and upload your video recording. Replay will automatically begin analyzing the video and generating code.

Step 3: Review and Customize the Generated Code#

Once Replay has finished processing the video, you'll be presented with a preview of the generated UI. You can review the code and make any necessary customizations.

📝 Note: Replay generates clean, well-structured code that is easy to understand and modify.

Step 4: Integrate with Supabase (Optional)#

If you want to connect your UI to a backend, you can easily integrate with Supabase. Replay will automatically generate the necessary data models and API endpoints.

Step 5: Deploy Your UI#

Once you're satisfied with the generated code, you can deploy your UI to your preferred hosting platform.

Code Example: Generated React Component#

Here's an example of a React component generated by Replay:

typescript
// ProductCard.tsx
import React from 'react';

interface ProductCardProps {
  name: string;
  price: number;
  imageUrl: string;
  onClick: () => void;
}

const ProductCard: React.FC<ProductCardProps> = ({ name, price, imageUrl, onClick }) => {
  return (
    <div className="product-card" onClick={onClick}>
      <img src={imageUrl} alt={name} className="product-image" />
      <h3 className="product-name">{name}</h3>
      <p className="product-price">${price.toFixed(2)}</p>
    </div>
  );
};

export default ProductCard;

This is a simple but functional React component that displays a product card. Replay automatically generated the component structure, props, and basic styling based on the video recording.

Handling Complex Interactions#

Replay excels at handling complex user interactions. For example, consider a scenario where a user filters a product list based on multiple criteria (e.g., price range, color, size).

Replay can analyze the video recording of this interaction and generate code that accurately reflects the filtering logic. This includes:

• •Generating the UI elements for the filter controls (e.g., dropdown menus, sliders)
• •Implementing the filtering logic in the backend (e.g., using Supabase functions)
• •Updating the UI to display the filtered results

typescript
// Example: Filtering logic using Supabase
const filterProducts = async (priceRange: { min: number; max: number }, color: string) => {
  const { data, error } = await supabase
    .from('products')
    .select('*')
    .gte('price', priceRange.min)
    .lte('price', priceRange.max)
    .eq('color', color);

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

  return data;
};

⚠️ Warning: While Replay automates much of the development process, it's important to review the generated code and make any necessary adjustments.

Benefits of Using Replay#

• •Faster Development: Reconstruct UIs in minutes instead of days.
• •Increased Accuracy: Eliminate errors and inconsistencies caused by manual coding.
• •Improved Collaboration: Easily share and iterate on UI designs with your team.
• •Reduced Costs: Save time and resources on UI development.
• •Focus on Innovation: Spend more time on core product features and less time on tedious UI coding.

Frequently Asked Questions#

Is Replay free to use?#

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

How is Replay different from v0.dev?#

While v0.dev generates UI components based on text prompts, Replay analyzes video of user interactions to reconstruct entire UIs. Replay understands user behavior, while v0.dev only understands text.

What frameworks does Replay support?#

Replay currently supports React, Vue, and Angular. Support for other frameworks is planned for the future.

Can I use Replay with existing codebases?#

Yes, Replay can be integrated with existing codebases. The generated code is clean and modular, making it easy to incorporate into your project.
