How to Recreate a Modern Admin Panel from Video to React with Replay in 2026

TL;DR: Recreate a fully functional React admin panel from a screen recording using Replay's behavior-driven reconstruction, including Supabase integration and style injection.

The future of UI development is here, and it's driven by behavior, not just pixels. In 2026, we're moving beyond static screenshot-to-code tools. We need solutions that understand intent. Enter Replay.

Replay is a video-to-code engine powered by Gemini, designed to reconstruct working UI from screen recordings. Unlike traditional methods, Replay analyzes video to understand user behavior and intent, providing a more accurate and functional code representation. This article will guide you through recreating a modern admin panel from a simple screen recording using Replay, complete with Supabase integration and style injection.

The Problem: Manual UI Reconstruction is Slow and Error-Prone#

Building an admin panel from scratch is a time-consuming process. Traditional methods involve:

1. •Designing the UI in a tool like Figma or Adobe XD.
2. •Writing the code (HTML, CSS, JavaScript/TypeScript) to match the design.
3. •Connecting the UI to a backend database.
4. •Implementing user authentication and authorization.
5. •Testing and debugging the entire application.

This process is not only tedious but also prone to errors. Maintaining consistency between the design and the code can be challenging, and debugging UI issues can be particularly difficult. Screenshot-to-code tools offer a limited solution, often producing brittle code that requires significant manual cleanup. They lack the understanding of user flows and interactions, leading to incomplete or inaccurate reconstructions.

Replay offers a paradigm shift. By analyzing video, it captures the behavior of the user interacting with the UI, allowing for a more intelligent and accurate reconstruction of the code.

Replay: Behavior-Driven Reconstruction Explained#

Replay leverages "Behavior-Driven Reconstruction" (BDR), treating the video as the source of truth. This means Replay analyzes the video to understand:

• •User interactions (clicks, scrolls, form submissions).
• •Data flow (how data is entered, displayed, and updated).
• •Application logic (how different parts of the UI interact with each other).

This understanding allows Replay to generate code that not only looks like the original UI but also behaves like it.

Here's a comparison of Replay with other code generation tools:

As you can see, Replay stands out with its ability to analyze video and generate high-quality, customizable code.

Recreating an Admin Panel: A Step-by-Step Guide#

Let's walk through the process of recreating a modern admin panel from a video using Replay. We'll cover the key steps, including recording the video, using Replay to generate the code, integrating with Supabase, and injecting custom styles.

Step 1: Recording the Admin Panel Demonstration Video#

The first step is to record a video demonstrating the admin panel's functionality. This video should showcase all the key features and user interactions, including:

• •Navigation between different sections of the admin panel (e.g., dashboard, users, products, settings).
• •Creating, reading, updating, and deleting data (CRUD operations).
• •Filtering and sorting data.
• •User authentication and authorization (if applicable).

💡 Pro Tip: Keep the video concise and focused. Avoid unnecessary pauses or distractions. The clearer the video, the better Replay can understand the user behavior. Aim for a resolution of at least 720p for optimal analysis.

Step 2: Uploading the Video to Replay#

Once you have recorded the video, upload it to Replay. Replay will then begin analyzing the video to understand the UI structure, user interactions, and data flow. This process may take a few minutes, depending on the length and complexity of the video.

Step 3: Reviewing and Customizing the Generated Code#

After Replay has finished analyzing the video, it will generate React code that represents the admin panel. You can then review and customize the generated code to meet your specific requirements.

Replay provides a visual editor that allows you to inspect the UI elements and their corresponding code. You can modify the code directly in the editor, and Replay will automatically update the UI preview.

📝 Note: Replay aims to generate a functional and well-structured codebase. However, manual adjustments are often necessary to fine-tune the UI and add custom logic.

Step 4: Integrating with Supabase#

Replay offers seamless integration with Supabase, a popular open-source Firebase alternative. To integrate with Supabase, you'll need to:

1. •Create a Supabase project.
2. •Obtain your Supabase API URL and API key.
3. •Configure Replay to connect to your Supabase project.

Once you have configured the Supabase integration, Replay can automatically generate the necessary code to interact with your Supabase database. This includes code for:

• •Fetching data from Supabase tables.
• •Inserting new data into Supabase tables.
• •Updating existing data in Supabase tables.
• •Deleting data from Supabase tables.

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

typescript
// Example code generated by Replay
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);

const fetchData = async () => {
  const { data, error } = await supabase
    .from('users')
    .select('*');

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

  return data;
};

export default fetchData;

This code snippet demonstrates how Replay simplifies the process of connecting your UI to a backend database.

Step 5: Injecting Custom Styles#

Replay allows you to inject custom styles into the generated UI. This allows you to customize the look and feel of the admin panel to match your brand.

You can inject styles using CSS or a CSS-in-JS library like Styled Components or Emotion. Replay provides a simple API for adding custom styles to the generated code.

Here's an example of how to inject custom styles using CSS:

css
/* Example CSS */
.admin-panel {
  background-color: #f0f2f5;
  font-family: sans-serif;
}

.admin-panel-header {
  background-color: #fff;
  padding: 20px;
  border-bottom: 1px solid #ddd;
}

You can then import this CSS file into your React component and apply the styles to the corresponding UI elements.

Step 6: Product Flow Maps and Multi-Page Generation#

Replay excels at generating multi-page applications. Its ability to understand user flows allows it to reconstruct complex navigation patterns and relationships between different pages. The "Product Flow Maps" feature visualizes these flows, making it easier to understand the application's structure and identify potential areas for improvement.

This is especially useful for admin panels, which often consist of multiple pages for managing different aspects of the application. Replay can automatically generate the necessary routes and navigation links to create a seamless user experience.

Benefits of Using Replay#

Using Replay to recreate an admin panel from video offers several benefits:

• •Faster Development: Replay significantly reduces the time required to build a UI.
• •Higher Accuracy: Behavior-driven reconstruction ensures that the generated code accurately reflects the intended behavior of the UI.
• •Improved Code Quality: Replay generates well-structured and maintainable code.
• •Seamless Integration: Replay integrates seamlessly with Supabase and other popular backend services.
• •Enhanced Customization: Replay allows you to inject custom styles and logic to tailor the UI to your specific needs.

Alternatives to Replay#

While Replay offers a unique approach to UI reconstruction, several alternative tools are available. Here's a comparison:

⚠️ Warning: While other tools may offer similar features, Replay's unique video-to-code approach provides a more accurate and behaviorally-driven reconstruction.

Frequently Asked Questions#

Is Replay free to use?#
