TL;DR: Replay lets you create responsive websites from video recordings, leveraging AI to understand user behavior and generate working code in minutes.
From Video to Website: The Future of Responsive Design is Here#
Building responsive websites can be a time-consuming process, often involving complex coding, meticulous testing, and endless adjustments to ensure a seamless user experience across various devices. What if you could bypass much of this manual work and generate a functional, responsive website directly from a video recording? That's the promise of behavior-driven code generation, and it's now a reality with Replay.
Replay analyzes video of a user interacting with a desired interface to reconstruct a working website. This approach, leveraging advanced AI models like Gemini, moves beyond simple screenshot-to-code tools by understanding intent and generating code that reflects that understanding.
Understanding Behavior-Driven Reconstruction#
Traditional design-to-code solutions often rely on static images or design files. These methods capture the visual appearance but fail to capture the dynamic behavior and user interactions that are crucial for a great user experience. Replay takes a different approach, using video as the source of truth.
By analyzing video recordings of user flows, Replay can:
- •Identify UI elements and their relationships
- •Understand user actions (clicks, scrolls, form submissions)
- •Infer the intended functionality and data flow
This "behavior-driven reconstruction" allows Replay to generate code that is not only visually accurate but also functionally complete, resulting in a responsive website that behaves as intended.
Replay in Action: A Step-by-Step Guide#
Let's walk through a simple example of how you can use Replay to create a responsive website from a video recording.
Step 1: Capture Your Video#
First, record a video of yourself interacting with a website or application that you want to recreate. Be sure to clearly demonstrate the key user flows and interactions. For example, you might record yourself:
- •Navigating through different pages
- •Filling out forms
- •Clicking buttons
- •Scrolling through content
The clearer and more comprehensive your video, the better the results will be.
📝 Note: Ensure the video is well-lit and the UI elements are clearly visible.
Step 2: Upload to Replay#
Next, upload your video to Replay. The platform will automatically analyze the video and begin the reconstruction process.
Step 3: Review and Refine#
Once the analysis is complete, Replay will present you with a working website based on your video. You can then review the generated code and make any necessary refinements.
💡 Pro Tip: Replay allows you to inject custom styles and integrate with Supabase for backend functionality.
Step 4: Deploy Your Responsive Website#
Finally, you can deploy your responsive website to your preferred hosting provider. Replay generates clean, well-structured code that is easy to maintain and extend.
Code Example: Generated React Component#
Here's an example of a React component that Replay might generate from a video recording of a simple login form:
typescript// Generated by Replay import React, { useState } from 'react'; const LoginForm = () => { const [username, setUsername] = useState(''); const [password, setPassword] = useState(''); const handleSubmit = async (e: React.FormEvent) => { e.preventDefault(); // Simulate API call (replace with your actual login logic) const response = await fetch('/api/login', { method: 'POST', body: JSON.stringify({ username, password }), headers: { 'Content-Type': 'application/json', }, }); if (response.ok) { alert('Login successful!'); } else { alert('Login failed.'); } }; return ( <form onSubmit={handleSubmit}> <div> <label htmlFor="username">Username:</label> <input type="text" id="username" value={username} onChange={(e) => setUsername(e.target.value)} /> </div> <div> <label htmlFor="password">Password:</label> <input type="password" id="password" value={password} onChange={(e) => setPassword(e.target.value)} /> </div> <button type="submit">Login</button> </form> ); }; export default LoginForm;
This code snippet demonstrates how Replay can generate functional React components, complete with state management and event handling, directly from video analysis.
Replay vs. Traditional Methods: A Comparative Analysis#
How does Replay stack up against traditional website creation methods and other AI-powered tools? Let's take a look.
| Feature | Traditional Coding | Design-to-Code Tools | Replay |
|---|---|---|---|
| Time to Market | Weeks/Months | Days/Weeks | Minutes/Hours |
| Learning Curve | Steep | Moderate | Low |
| Responsiveness | Manual Implementation | Limited Responsiveness | Automatic |
| Behavior Analysis | Manual Implementation | Limited | ✅ |
| Video Input | ❌ | ❌ | ✅ |
| Supabase Integration | Manual Implementation | Limited | ✅ |
| Multi-Page Generation | Manual Implementation | Limited | ✅ |
| Style Injection | Manual Implementation | Limited | ✅ |
| Product Flow Maps | Manual Implementation | Limited | ✅ |
| Accuracy | High (if skilled) | Moderate | High |
| Cost | High (developer salaries) | Moderate (subscription fees) | Competitive |
As you can see, Replay offers significant advantages in terms of speed, ease of use, and behavior analysis. While traditional coding provides the highest level of control, it requires significant time and expertise. Design-to-code tools can speed up the process but often lack the ability to capture dynamic behavior. Replay bridges the gap by leveraging AI to understand user intent and generate fully functional, responsive websites.
Addressing Common Concerns#
Code Quality#
Some developers may be concerned about the quality of code generated by AI. Replay addresses this concern by:
- •Using advanced AI models trained on a vast dataset of code
- •Generating clean, well-structured code that is easy to understand and maintain
- •Providing developers with the ability to review and refine the generated code
Customization#
Another concern is the level of customization possible with AI-generated code. Replay allows you to:
- •Inject custom styles to match your brand
- •Integrate with Supabase for backend functionality
- •Modify the generated code to add custom features and logic
Accuracy#
While Replay strives for high accuracy, it's important to remember that AI is not perfect. It's always a good idea to review the generated code and make any necessary corrections. The quality of the input video also greatly affects the accuracy of the output.
⚠️ Warning: While Replay automates much of the process, human review and refinement are still recommended for optimal results.
Benefits of Using Replay#
- •Rapid Prototyping: Quickly create prototypes from video recordings.
- •Accelerated Development: Generate working code in minutes, saving time and resources.
- •Improved Collaboration: Easily share video recordings and generated code with your team.
- •Enhanced User Experience: Create responsive websites that behave as intended.

Frequently Asked Questions#
Is Replay free to use?#
Replay offers a free tier with limited features and usage. Paid plans are available for more advanced features and higher usage limits. Check out the pricing page for more details.
How is Replay different from v0.dev?#
While both Replay and v0.dev aim to simplify website creation with AI, they take different approaches. v0.dev primarily uses text prompts to generate UI components, while Replay analyzes video recordings to reconstruct entire websites based on user behavior. Replay focuses on capturing the dynamic aspects of a user interface, going beyond static visual representations.
What kind of videos work best with Replay?#
Videos with clear, well-lit UI elements and distinct user interactions work best. Make sure to showcase all the important features and user flows you want Replay to capture.
Can I use Replay to recreate complex web applications?#
Replay is designed to handle a wide range of web applications, from simple landing pages to more complex interactive interfaces. However, the complexity of the application and the clarity of the input video will affect the accuracy and completeness of the generated code.
What frameworks and libraries does Replay support?#
Replay generates code compatible with popular front-end frameworks like React. Further framework support is planned for future releases.
