How to Rebuild an Enterprise Resource Planning (ERP) System from Video with React & Replay 2026

TL;DR: Forget screenshot-to-code – Replay lets you rebuild an entire ERP system from video recordings, leveraging behavior-driven reconstruction for accurate and functional React code.

The "screenshot-to-code" gold rush is over. It's a party trick, not a solution for real-world applications. Static images can't capture user flows, dynamic data, or intricate interactions. Trying to rebuild an Enterprise Resource Planning (ERP) system – a complex beast of workflows and data management – from screenshots alone? Forget about it.

The future is video. Specifically, video-to-code powered by AI that understands behavior. That's where Replay comes in.

Why Video-to-Code is the Only Way to Rebuild Complex Systems#

ERP systems are notoriously difficult to modernize. They're often built on legacy codebases, riddled with technical debt, and crucial to business operations. A complete rewrite is a massive undertaking, fraught with risk. But what if you could reconstruct the system, piece by piece, by analyzing how users actually use it?

That's the power of Replay. By analyzing video recordings of users interacting with the existing ERP, Replay can:

• •Understand the underlying business logic.
• •Identify key user flows and data dependencies.
• •Generate clean, functional React code that mirrors the original system's behavior.

This approach, which we call "Behavior-Driven Reconstruction," is a game-changer. It's not about replicating pixels; it's about understanding intent.

Rebuilding an ERP System: A Practical Example#

Let's say you want to modernize the inventory management module of your ERP. You have video recordings of warehouse staff using the existing system to:

• •Receive new shipments.
• •Track inventory levels.
• •Process orders.
• •Manage returns.

With Replay, you can feed these videos into the engine, and it will generate React components that replicate these workflows.

Step 1: Video Capture and Upload#

Record videos of users performing key tasks within the inventory management module. Ensure the videos are clear and capture the entire screen, including user interactions and data entry. Upload these videos to the Replay platform.

💡 Pro Tip: Use a screen recording tool that allows you to annotate the video with user stories or task descriptions. This will help Replay better understand the context of the video.

Step 2: Behavior Analysis and Code Generation#

Replay's AI engine analyzes the videos, identifying UI elements, user interactions, and data flows. It then generates React code that replicates the observed behavior. This includes:

• •Component structure (e.g., forms, tables, buttons).
• •Event handlers (e.g.,
  text

  onClick
  ,
  text

  onChange
  ).
• •Data bindings (e.g., displaying inventory levels).
• •API calls (e.g., updating inventory records).

Step 3: Code Review and Customization#

Review the generated code to ensure it meets your requirements. You can customize the code to:

• •Improve performance.
• •Enhance the UI.
• •Integrate with your existing backend systems.

📝 Note: Replay provides tools for easily editing and customizing the generated code. You can also inject custom styles and logic to tailor the code to your specific needs.

Here's an example of React code generated by Replay for a simple inventory update form:

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

const InventoryUpdateForm = () => {
  const [itemId, setItemId] = useState('');
  const [quantity, setQuantity] = useState(0);

  const handleSubmit = async (event: React.FormEvent) => {
    event.preventDefault();
    try {
      const response = await fetch('/api/updateInventory', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
        },
        body: JSON.stringify({ itemId, quantity }),
      });

      if (response.ok) {
        alert('Inventory updated successfully!');
      } else {
        alert('Failed to update inventory.');
      }
    } catch (error) {
      console.error('Error updating inventory:', error);
      alert('An error occurred.');
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label htmlFor="itemId">Item ID:</label>
        <input
          type="text"
          id="itemId"
          value={itemId}
          onChange={(e) => setItemId(e.target.value)}
        />
      </div>
      <div>
        <label htmlFor="quantity">Quantity:</label>
        <input
          type="number"
          id="quantity"
          value={quantity}
          onChange={(e) => setQuantity(parseInt(e.target.value))}
        />
      </div>
      <button type="submit">Update Inventory</button>
    </form>
  );
};

export default InventoryUpdateForm;

This code, generated directly from video analysis, provides a functional starting point for modernizing your inventory management module.

Step 4: Integration and Deployment#

Integrate the generated React components into your existing ERP system or a new microservices architecture. Deploy the updated module to your production environment.

Replay vs. Traditional Approaches: A Clear Win#

Let's compare Replay to traditional methods of ERP modernization:

As you can see, Replay offers a compelling balance of accuracy, speed, and cost, while also providing unique capabilities for understanding and replicating user behavior.

Beyond Basic Code Generation: Advanced Features#

Replay goes beyond basic code generation with features designed for complex applications like ERP systems:

• •Multi-Page Generation: Replay can analyze videos that span multiple pages and workflows, generating code for entire user flows.
• •Supabase Integration: Seamlessly integrate your generated code with Supabase for backend services, data storage, and authentication.
• •Style Injection: Apply custom styles to your generated components to match your existing design system.
• •Product Flow Maps: Visualize user flows and identify areas for optimization.

⚠️ Warning: While Replay significantly accelerates the development process, it's crucial to have experienced developers review and customize the generated code to ensure it meets your specific requirements and security standards.

The Future of ERP Modernization#

Replay represents a paradigm shift in how we approach ERP modernization. By leveraging the power of video and AI, we can:

• •Reduce the risk and cost of traditional rewrites.
• •Accelerate the development process.
• •Ensure that the modernized system accurately reflects user needs and workflows.

The days of painstakingly reverse-engineering legacy systems are over. The future is behavior-driven reconstruction.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited features and usage. Paid plans are available for larger projects and advanced capabilities.

How is Replay different from v0.dev?#

v0.dev is a text-to-code tool, relying on prompts to generate UI components. Replay analyzes video of real user interactions, understanding the underlying behavior and generating more accurate and functional code. Replay focuses on rebuilding existing systems, while v0.dev is geared towards creating new UIs from scratch.

What types of ERP systems can Replay handle?#

Replay can handle a wide range of ERP systems, regardless of the underlying technology. The key requirement is having access to video recordings of users interacting with the system.

What if the video quality is poor?#

While clear video is ideal, Replay is designed to be robust to variations in video quality. However, extremely blurry or distorted video may impact the accuracy of the generated code.

What security measures are in place to protect sensitive data in the videos?#

Replay employs industry-standard security measures to protect user data, including encryption, access controls, and regular security audits. We recommend anonymizing or redacting sensitive data in the videos before uploading them to the platform.
