How Replay AI converts Webflow designs to React code with pixel-perfect accuracy

TL;DR: Replay AI accurately converts Webflow design videos into production-ready React code by analyzing user behavior and UI interactions, going beyond simple screenshot-to-code conversion.

Webflow is fantastic for visual web design, but migrating those designs to a robust React codebase can be a painful, manual process. You're essentially rebuilding your UI from scratch, pixel by pixel. Screenshot-to-code tools offer a quick fix, but they often fall short, producing brittle code that misses the nuances of user interactions and dynamic elements. What if you could simply record a video of your Webflow design in action and have it automatically converted into clean, functional React code? That's where Replay comes in.

The Problem with Traditional Screenshot-to-Code#

Screenshot-to-code solutions treat your UI as a static image. They can generate basic HTML and CSS, but they fail to capture the dynamic behavior and intent behind your design. This leads to:

• •Inaccurate representation of animations and transitions: Screenshots are static; they don't show how elements move or change over time.
• •Lack of interactivity: Buttons, forms, and other interactive elements are just images. You still need to manually implement the logic behind them.
• •Poor code quality: The generated code is often bloated, difficult to maintain, and doesn't follow best practices.
• •Inability to handle multi-page flows: Screenshot tools typically only process one screen at a time, making it difficult to reconstruct complex user flows.

Replay: Behavior-Driven Reconstruction#

Replay takes a fundamentally different approach. Instead of relying on static screenshots, Replay analyzes videos of your Webflow design. It uses advanced AI, powered by Gemini, to understand user behavior and reconstruct the UI based on those interactions. This "Behavior-Driven Reconstruction" ensures that the generated React code accurately reflects the intended functionality and user experience.

How Replay Works#

1. •Record a video: Capture a video of your Webflow design in action, demonstrating all the key interactions and user flows.
2. •Upload to Replay: Upload the video to the Replay platform.
3. •AI Analysis: Replay analyzes the video, identifying UI elements, user interactions, and design patterns.
4. •React Code Generation: Replay generates clean, functional React code, complete with components, styles, and event handlers.
5. •Integration: Integrate the generated code into your existing React project.

💡 Pro Tip: The more comprehensive your video, the more accurate the resulting code will be. Show all states of your UI elements (hover, active, disabled), and demonstrate all possible user flows.

Key Features of Replay#

• •Multi-page Generation: Replay can analyze videos of multi-page flows and generate corresponding React routes and components.
• •Supabase Integration: Seamlessly integrate your generated React code with Supabase for backend functionality.
• •Style Injection: Replay intelligently injects styles, either inline or using CSS-in-JS libraries, to maintain the visual fidelity of your Webflow design.
• •Product Flow Maps: Replay generates visual maps of your product flows, making it easy to understand the structure and navigation of your application.

Replay in Action: Converting a Webflow Form to React#

Let's say you have a simple contact form in Webflow. Here's how Replay can convert it to React code:

Step 1: Record a Video#

Record a video of yourself interacting with the Webflow form. Show yourself typing in the fields, clicking the submit button, and interacting with any error messages or success states.

Step 2: Upload to Replay#

Upload the video to the Replay platform.

Step 3: Review and Refine#

Review the generated React code. Replay provides a visual interface for making adjustments and refinements.

Step 4: Integrate into Your React Project#

Copy and paste the generated code into your React project.

Here's an example of the kind of React code Replay can generate from a Webflow form video:

typescript
// ContactForm.tsx
import React, { useState } from 'react';

interface FormData {
  name: string;
  email: string;
  message: string;
}

const ContactForm: React.FC = () => {
  const [formData, setFormData] = useState<FormData>({
    name: '',
    email: '',
    message: '',
  });

  const handleChange = (e: React.ChangeEvent<HTMLInputElement | HTMLTextAreaElement>) => {
    const { name, value } = e.target;
    setFormData(prevState => ({
      ...prevState,
      [name]: value,
    }));
  };

  const handleSubmit = async (e: React.FormEvent) => {
    e.preventDefault();
    // Simulate API call (replace with your actual API endpoint)
    try {
      const response = await fetch('/api/contact', {
        method: 'POST',
        headers: {
          'Content-Type': 'application/json',
        },
        body: JSON.stringify(formData),
      });

      if (response.ok) {
        alert('Message sent successfully!');
        setFormData({ name: '', email: '', message: '' }); // Reset form
      } else {
        alert('Error sending message. Please try again.');
      }
    } catch (error) {
      console.error('Error:', error);
      alert('Error sending message. Please try again.');
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <div>
        <label htmlFor="name">Name:</label>
        <input type="text" id="name" name="name" value={formData.name} onChange={handleChange} required />
      </div>
      <div>
        <label htmlFor="email">Email:</label>
        <input type="email" id="email" name="email" value={formData.email} onChange={handleChange} required />
      </div>
      <div>
        <label htmlFor="message">Message:</label>
        <textarea id="message" name="message" value={formData.message} onChange={handleChange} required />
      </div>
      <button type="submit">Send Message</button>
    </form>
  );
};

export default ContactForm;

This code includes:

• •React components for each form element.
• •State management using
  text

  useState
  to handle form input.
• •Event handlers for input changes and form submission.
• •Basic form validation.
• •A placeholder for your actual API call to handle form submission.

📝 Note: This is a simplified example. Replay can generate more complex code based on the complexity of your Webflow design and the interactions you demonstrate in the video.

typescript
// Example of fetching data in a React component generated by Replay
import React, { useState, useEffect } from 'react';

const DataDisplay: React.FC = () => {
  const [data, setData] = useState<any>(null);
  const [loading, setLoading] = useState<boolean>(true);
  const [error, setError] = useState<string | null>(null);

  useEffect(() => {
    const fetchData = async () => {
      try {
        const response = await fetch('/api/data'); // Replace with your API endpoint
        if (!response.ok) {
          throw new Error(`HTTP error! status: ${response.status}`);
        }
        const jsonData = await response.json();
        setData(jsonData);
      } catch (e: any) {
        setError(e.message);
      } finally {
        setLoading(false);
      }
    };

    fetchData();
  }, []); // Empty dependency array ensures this effect runs only once on mount

  if (loading) {
    return <div>Loading data...</div>;
  }

  if (error) {
    return <div>Error: {error}</div>;
  }

  return (
    <div>
      {data && (
        <pre>{JSON.stringify(data, null, 2)}</pre> // Display the data in a formatted way
      )}
    </div>
  );
};

export default DataDisplay;
