Replay vs Figma Plugins: Is AI-Powered Video Conversion the Future of Design-to-Code?

TL;DR: Replay's AI-powered video-to-code engine offers a behavior-driven approach to UI reconstruction, surpassing traditional Figma plugins that rely on static screenshots.

The promise of instantly converting designs into working code has tantalized developers and designers for years. Figma plugins have emerged as popular solutions, streamlining the design-to-code workflow. However, these plugins often fall short in capturing the intent behind the design, leading to brittle and incomplete code. Replay offers a fundamentally different approach: behavior-driven reconstruction from video.

The Limitations of Figma Plugins#

Figma plugins excel at extracting visual elements and properties from static designs. But the reality is that user interfaces are dynamic. They respond to user interactions, manage state, and execute complex logic. Figma plugins, limited by their reliance on static representations, struggle to capture this dynamic behavior.

Here's a breakdown of the common issues:

• •Lack of Context: Plugins treat designs as static images, missing the underlying logic and user flows.
• •Manual Adjustments: The generated code often requires significant manual tweaking to handle dynamic behavior and data integration.
• •Limited Scope: Most plugins focus on individual components or screens, failing to generate complete, multi-page applications.
• •Version Control Challenges: Keeping the generated code synchronized with design updates can be a cumbersome process.

Replay: Behavior-Driven Reconstruction from Video#

Replay takes a revolutionary approach to design-to-code. Instead of relying on static design files, Replay analyzes video recordings of user interactions to understand the underlying behavior and intent. This "behavior-driven reconstruction" enables Replay to generate more accurate, complete, and maintainable code.

How Replay Works#

Replay leverages the power of Gemini to analyze video recordings, identifying UI elements, user interactions, and data flows. It then uses this information to reconstruct a working UI, complete with state management, event handling, and data integration.

The core principles behind Replay's approach are:

1. •Video as Source of Truth: The video recording captures the complete user experience, including dynamic behavior and interactions.
2. •AI-Powered Analysis: Gemini analyzes the video to identify UI elements, user actions, and data flows.
3. •Behavior-Driven Reconstruction: Replay uses the analyzed behavior to generate code that accurately reflects the intended functionality.
4. •Iterative Refinement: Replay allows you to refine the generated code and provide feedback, continuously improving its accuracy and completeness.

Key Features of Replay#

• •Multi-Page Generation: Replay can generate complete, multi-page applications from a single video recording, capturing complex user flows and interactions.
• •Supabase Integration: Replay seamlessly integrates with Supabase, allowing you to quickly connect your UI to a backend database and manage data persistence.
• •Style Injection: Replay can automatically inject styles into your generated code, ensuring a consistent and visually appealing user interface.
• •Product Flow Maps: Replay generates visual product flow maps, helping you understand and optimize the user journey through your application.

Building a Simple App with Replay: A Step-by-Step Guide#

Let's walk through a simple example of using Replay to generate code from a video recording of a basic to-do list application.

Step 1: Record the Video#

Record a video of yourself interacting with a to-do list application. Make sure to include the following interactions:

• •Adding new tasks
• •Marking tasks as complete
• •Deleting tasks

💡 Pro Tip: Speak clearly while interacting with the app. Narrating your actions helps Replay better understand your intent.

Step 2: Upload to Replay#

Upload the video recording to Replay. Replay will begin analyzing the video and reconstructing the UI.

Step 3: Review and Refine#

Once Replay has finished analyzing the video, review the generated code. You can refine the code by providing feedback and making adjustments.

Step 4: Integrate with Supabase (Optional)#

If you want to persist the to-do list data, you can integrate Replay with Supabase. Replay will automatically generate the necessary code to connect your UI to your Supabase database.

Step 5: Deploy and Share#

Once you are satisfied with the generated code, you can deploy your application and share it with others.

Example Code Generated by Replay#

Here's an example of the code that Replay might generate for a simple to-do list component:

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

interface TodoItemProps {
  id: number;
  text: string;
  completed: boolean;
  onToggle: (id: number) => void;
  onDelete: (id: number) => void;
}

const TodoItem: React.FC<TodoItemProps> = ({ id, text, completed, onToggle, onDelete }) => {
  return (
    <li className="todo-item">
      <input
        type="checkbox"
        checked={completed}
        onChange={() => onToggle(id)}
      />
      <span className={completed ? 'completed' : ''}>{text}</span>
      <button onClick={() => onDelete(id)}>Delete</button>
    </li>
  );
};

export default TodoItem;

This code snippet demonstrates how Replay can accurately capture the structure and behavior of a UI element from a video recording. The

component includes state management (implicitly handled by the parent component), event handling (the and handlers), and styling (the class).

Furthermore, Replay can generate the API endpoints required to interact with Supabase:

typescript
// pages/api/todos.ts
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);

export default async function handler(req: any, res: any) {
  if (req.method === 'POST') {
    const { text } = req.body;
    const { data, error } = await supabase
      .from('todos')
      .insert([{ text }])
      .select();

    if (error) {
      return res.status(500).json({ error: error.message });
    }

    return res.status(200).json({ data });
  } else {
    return res.status(405).json({ message: 'Method Not Allowed' });
  }
}

This example showcases Replay's ability to generate backend code that seamlessly integrates with Supabase, streamlining the development process.

⚠️ Warning: Replay is still under active development, and the generated code may require some manual adjustments. However, the behavior-driven approach significantly reduces the amount of manual work required compared to traditional Figma plugins.
