Replay vs screenshot-to-code: Which generates the better UI with accessibility from video (2026)?

TL;DR: Replay, leveraging behavior-driven reconstruction from video, surpasses screenshot-to-code tools in generating accessible and functional UIs that accurately reflect user intent, especially when dealing with complex, multi-page flows.

Screenshot-to-code tools are relics of the past. In 2026, expecting them to deliver high-fidelity, accessible, and functional UI from a single static image is like expecting a map to drive your car. They can give you a general idea, but they fundamentally misunderstand the dynamic behavior that makes a UI truly usable. The future is video-to-code. And that future is now.

The Problem with Static Snapshots: A Functional Dead End#

Screenshot-to-code tools suffer from inherent limitations. They treat UI as a static visual representation, ignoring the underlying logic, user interactions, and accessibility considerations that breathe life into a digital experience. They can produce visually similar code, but the result is often riddled with accessibility issues, broken interactions, and a complete lack of understanding of the intended user flow.

Consider a simple e-commerce checkout process. A screenshot-to-code tool might be able to reproduce the visual layout of the payment page. But it won't understand:

• •How the user navigated to that page.
• •The data dependencies between form fields.
• •The logic behind conditional display of shipping options.
• •The necessary ARIA attributes for screen reader compatibility.

The result? A visually appealing but functionally useless facade. You're left spending countless hours manually wiring up the logic, fixing accessibility violations, and reverse-engineering the intended user experience.

Replay: Behavior-Driven Reconstruction from Video#

Replay takes a radically different approach. Instead of relying on static images, Replay analyzes video recordings of user interactions. This "behavior-driven reconstruction" allows Replay to understand not just what the user sees, but how they interact with the UI, why they make certain choices, and what the intended outcome is.

Replay's Gemini-powered engine dissects the video frame by frame, identifying UI elements, tracking user actions (clicks, scrolls, form inputs), and inferring the underlying logic. This holistic understanding enables Replay to generate code that is:

• •Functional: The generated UI behaves as intended, mirroring the user's interactions in the video.
• •Accessible: Replay automatically infers and implements appropriate ARIA attributes, keyboard navigation, and semantic HTML to ensure accessibility for all users.
• •Maintainable: The generated code is clean, well-structured, and easily customizable, allowing for seamless integration into existing projects.

Key Features of Replay#

• •Multi-page generation: Replay can reconstruct entire user flows spanning multiple pages, understanding the relationships between different UI elements and data dependencies.
• •Supabase integration: Seamlessly connect your Replay-generated UI to a Supabase backend, enabling real-time data synchronization and persistent storage.
• •Style injection: Easily customize the look and feel of your Replay-generated UI with custom CSS or styling frameworks.
• •Product Flow maps: Visualize the user journey reconstructed by Replay, providing a clear overview of the intended product flow.

Replay vs. Screenshot-to-Code: A Head-to-Head Comparison#

The table speaks for itself. While screenshot-to-code tools might offer a quick and dirty way to generate a basic UI skeleton, Replay delivers a complete, functional, and accessible UI that accurately reflects the intended user experience.

From Video to Code: A Practical Example#

Let's say you have a video recording of a user creating an account on a website. Here's how you can use Replay to generate the corresponding UI code:

Step 1: Upload the Video to Replay#

Simply upload the video recording to the Replay platform. Replay will automatically analyze the video and identify the relevant UI elements and user interactions.

Step 2: Review and Refine the Generated Code#

Replay generates a React component representing the account creation form. You can review the generated code and make any necessary adjustments.

typescript
// Replay-generated React component for account creation
import React, { useState } from 'react';

const CreateAccountForm = () => {
  const [email, setEmail] = useState('');
  const [password, setPassword] = useState('');

  const handleSubmit = async (e: React.FormEvent) => {
    e.preventDefault();
    // Placeholder for API call
    console.log('Submitting form with:', { email, password });
    // In real implementation you would call an API here
  };

  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label htmlFor="email">Email:</label>
        <input
          type="email"
          id="email"
          value={email}
          onChange={(e) => setEmail(e.target.value)}
          aria-label="Email Address"
          required
        />
      </div>
      <div>
        <label htmlFor="password">Password:</label>
        <input
          type="password"
          id="password"
          value={password}
          onChange={(e) => setPassword(e.target.value)}
          aria-label="Password"
          required
        />
      </div>
      <button type="submit">Create Account</button>
    </form>
  );
};

export default CreateAccountForm;

💡 Pro Tip: Replay infers ARIA labels based on the context of the video, significantly improving accessibility.

Step 3: Integrate with Supabase (Optional)#

Connect your Replay-generated UI to your Supabase backend to enable real-time data synchronization and persistent storage. Replay provides pre-built integrations that simplify this process.

typescript
// Example of Supabase integration (conceptual)
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = 'YOUR_SUPABASE_URL';
const supabaseKey = 'YOUR_SUPABASE_ANON_KEY';
const supabase = createClient(supabaseUrl, supabaseKey);

const handleSubmit = async (e: React.FormEvent) => {
  e.preventDefault();
  const { data, error } = await supabase
    .from('users')
    .insert([{ email, password }]);

  if (error) {
    console.error('Error creating user:', error);
  } else {
    console.log('User created successfully:', data);
  }
};

📝 Note: This is a simplified example. In a real-world scenario, you would need to handle error cases, implement proper authentication, and securely store passwords.

The Future of UI Development is Behavior-Driven#

The limitations of screenshot-to-code tools are becoming increasingly apparent. As UI complexity grows and accessibility standards become more stringent, developers need a more intelligent and reliable solution. Replay offers that solution by leveraging the power of video analysis and behavior-driven reconstruction.

By understanding user intent and capturing the nuances of user interactions, Replay empowers developers to generate high-quality, functional, and accessible UIs with unprecedented speed and accuracy. Replay isn't just about generating code; it's about understanding user behavior and translating that understanding into a seamless digital experience.

⚠️ Warning: While Replay significantly reduces development time, it's crucial to thoroughly test the generated code and ensure it meets your specific requirements.

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 functionality and higher usage limits.

How is Replay different from v0.dev?#

While v0.dev focuses on generating UI components based on text prompts, Replay analyzes video recordings of user interactions to reconstruct entire user flows. Replay excels at understanding user intent and generating functional UIs with built-in accessibility. V0.dev relies on the accuracy of the prompt, while Replay relies on the accuracy of observed user behavior.

What types of videos work best with Replay?#

Replay works best with clear, high-resolution videos that capture the entire screen and user interactions. It's important to ensure that the video is free from distractions and that the UI elements are clearly visible.

What frameworks does Replay support?#

Currently, Replay primarily supports React. Support for other frameworks is planned for future releases.
