Best Lovable.dev Alternatives for UI Development from Video: Replay Is Fastest (2026)

TL;DR: Lovable.dev is dead, and Replay emerges as the fastest and most accurate alternative for generating code from video, leveraging behavior-driven reconstruction to build fully functional UIs.

The screenshot-to-code dream is over. Static images are a dead end for UI development. They lack context, user intent, and the dynamic nature of real-world applications. Lovable.dev promised a solution, but its sunsetting leaves a gap in the market. The good news? The future is video. And that future is now with Replay.

The Problem with Screenshot-to-Code#

Let's be honest: screenshot-to-code never really delivered. It's a clever gimmick that quickly hits a wall when dealing with complex interactions, multi-page flows, and dynamic data. You end up spending more time fixing the generated code than writing it from scratch.

Why? Because screenshots are static representations. They capture a single moment in time, missing the crucial behavior that defines a user interface. Consider a simple dropdown menu. A screenshot shows the menu open, but it doesn't tell you:

• •How the menu was triggered (click, hover, focus)
• •What data is dynamically populated in the menu
• •What happens when a user selects an option

Screenshot-to-code tools simply guess at these interactions, leading to brittle, unreliable code.

Replay: Behavior-Driven Reconstruction#

Replay takes a fundamentally different approach: behavior-driven reconstruction. Instead of analyzing static images, Replay analyzes video of user interactions. This allows Replay to understand what users are trying to do, not just what they see.

Replay leverages Gemini, Google's most advanced AI model, to deconstruct video into code. This isn't just about recognizing UI elements; it's about understanding the relationships between those elements and the user's actions.

This approach unlocks powerful capabilities:

• •Multi-Page Generation: Replay can seamlessly generate code for entire user flows, capturing the transitions between pages and the data passed between them.
• •Supabase Integration: Replay understands data dependencies and can automatically integrate with your Supabase backend, generating the necessary API calls and data bindings.
• •Style Injection: Replay analyzes the visual style of the video and injects it into the generated code, ensuring a consistent and polished look.
• •Product Flow Maps: Replay generates visual maps of the user flow, making it easy to understand and modify the application's logic.

Replay vs. the Alternatives#

Let's see how Replay stacks up against other Lovable.dev alternatives:

As you can see, Replay offers a unique combination of speed, accuracy, and flexibility. It's not just about generating code; it's about understanding user behavior and translating that into a functional application.

How to Use Replay: A Quick Tutorial#

Here's a simple example of how to use Replay to generate code from a video:

Step 1: Upload Your Video#

Simply upload a screen recording of your desired user flow to the Replay platform.

Step 2: Configure Your Project#

Specify your desired framework (React, Vue, etc.) and your Supabase credentials (if applicable).

Step 3: Generate Code#

Click the "Generate Code" button and let Replay do its magic.

Step 4: Review and Customize#

Review the generated code and make any necessary customizations. Replay provides a visual editor that allows you to easily modify the UI and logic.

Here's an example of the code Replay might generate for a simple React component based on a video of a user interacting with a form:

typescript
// Generated by Replay
import { useState } from 'react';
import { supabase } from './supabaseClient'; // Assuming Supabase setup

const MyForm = () => {
  const [name, setName] = useState('');
  const [email, setEmail] = useState('');

  const handleSubmit = async (e) => {
    e.preventDefault();
    try {
      const { data, error } = await supabase
        .from('users')
        .insert([{ name, email }]);

      if (error) {
        console.error('Error inserting data:', error);
      } else {
        console.log('Data inserted successfully:', data);
        // Reset form
        setName('');
        setEmail('');
      }
    } catch (err) {
      console.error('Unexpected error:', err);
    }
  };

  return (
    <form onSubmit={handleSubmit}>
      <label htmlFor="name">Name:</label>
      <input
        type="text"
        id="name"
        value={name}
        onChange={(e) => setName(e.target.value)}
      />

      <label htmlFor="email">Email:</label>
      <input
        type="email"
        id="email"
        value={email}
        onChange={(e) => setEmail(e.target.value)}
      />

      <button type="submit">Submit</button>
    </form>
  );
};

export default MyForm;

💡 Pro Tip: For best results, record videos with clear and consistent user interactions. Avoid sudden movements or distractions.

Replay also understands styling. Let's say the video showed the submit button with a specific background color and font. Replay will automatically inject the corresponding CSS:

css
/* Injected styles from Replay */
button[type="submit"] {
  background-color: #4CAF50;
  color: white;
  padding: 10px 20px;
  border: none;
  border-radius: 5px;
  cursor: pointer;
}

📝 Note: Replay's style injection can be customized to match your existing design system.

Why Replay is Faster#

Replay accelerates development in several key ways:

• •Eliminates manual UI coding: Replay generates the basic UI structure and styling, freeing you from repetitive tasks.
• •Automates backend integration: Replay automatically connects your UI to your Supabase backend, eliminating the need for manual API calls.
• •Reduces debugging time: Replay's behavior-driven approach ensures that the generated code accurately reflects the user's intended behavior, reducing the need for debugging.

⚠️ Warning: While Replay significantly accelerates development, it's not a magic bullet. You'll still need to review and customize the generated code to ensure it meets your specific requirements.

The Future of UI Development is Video#

Lovable.dev's demise highlights the limitations of screenshot-to-code. Replay offers a superior approach that leverages the power of video to understand user behavior and generate functional UIs. As video becomes an increasingly ubiquitous medium, Replay is poised to become the leading tool for rapid UI development.

Frequently Asked Questions#

Is Replay free to use?#

Replay offers a free tier with limited features. Paid plans are available for more advanced features and higher usage limits.

How is Replay different from v0.dev?#

v0.dev relies on AI to generate UI components based on text prompts. Replay, on the other hand, generates UI from video, capturing real user interactions and behavior. This leads to more accurate and functional code.

What frameworks does Replay support?#

Currently, Replay supports React, Vue, and HTML/CSS. Support for other frameworks is planned for the future.

Can I use Replay with other backends besides Supabase?#

While Replay has native integration with Supabase, you can customize the generated code to work with other backends.

How accurate is Replay?#

Replay's accuracy depends on the quality of the input video. Clear and consistent user interactions will result in more accurate code generation.
