Replay: The Ultimate Solution for Converting Video Prototypes to Production-Ready Code in 2026

TL;DR: Replay bridges the gap between video prototypes and production-ready code by leveraging AI-powered behavior analysis for accurate UI reconstruction.

Replay: The Ultimate Solution for Converting Video Prototypes to Production-Ready Code in 2026#

In 2026, the speed of prototyping directly impacts time-to-market. Designing a UI in Figma is fast, but turning that design into functional code? That's where the bottleneck lies. What if you could simply record a user interacting with a mockup and have working code generated automatically? That's the promise of Replay.

Traditional screenshot-to-code solutions offer limited value because they only understand visual elements. They can't decipher user intent or the flow of interactions. Replay solves this by analyzing video, using a "Behavior-Driven Reconstruction" approach. We treat the video as the single source of truth, allowing our AI to understand not just what the user sees, but what they are trying to do.

The Problem with Traditional UI Generation#

Most UI generation tools rely on static images. This approach is fundamentally flawed because it misses the crucial element of user behavior. Consider the following scenario: a user clicks a button, which triggers a modal. A screenshot-to-code tool sees two separate images: the initial state and the modal. It has no understanding of the interaction that connects them.

This leads to:

• •Incomplete or incorrect code generation
• •Lack of dynamic behavior
• •Difficulty in maintaining the generated code
• •Increased development time for adding interactivity

Replay's Behavior-Driven Reconstruction#

Replay addresses these shortcomings by analyzing video recordings of user interactions. This allows us to:

• •Understand the flow of the application
• •Identify user intents and actions
• •Generate code that accurately reflects the desired behavior
• •Create multi-page applications with seamless transitions

📝 Note: Replay leverages the power of Gemini to analyze video data and reconstruct the UI with a high degree of accuracy.

Key Features of Replay#

Replay offers a range of features designed to streamline the UI development process:

• •Multi-page generation: Reconstruct entire application flows from a single video.
• •Supabase integration: Seamlessly connect your generated UI to a Supabase backend.
• •Style injection: Customize the look and feel of your UI with CSS or Tailwind CSS.
• •Product Flow maps: Visualize the user flow and interactions captured in the video.

How Replay Works: A Step-by-Step Guide#

Here's a breakdown of how to use Replay to convert a video prototype into production-ready code:

Step 1: Recording Your Prototype

Record a video of yourself (or a user) interacting with your UI prototype. This could be a Figma prototype, a simple HTML mockup, or even a whiteboard sketch.

💡 Pro Tip: Speak clearly while interacting with the prototype, describing your actions and intentions. This helps Replay better understand the desired behavior.

Step 2: Uploading to Replay

Upload the video to the Replay platform. Our AI will begin analyzing the video to understand the UI elements and user interactions.

Step 3: Code Generation and Review

Replay generates the code for your UI, including HTML, CSS, and JavaScript. You can review the generated code and make any necessary adjustments.

Step 4: Integration and Deployment

Integrate the generated code into your existing project and deploy it to your platform of choice.

Code Example: Fetching Data from Supabase#

Here's an example of how Replay can generate code that integrates with Supabase:

typescript
// Generated by Replay
import { createClient } from '@supabase/supabase-js';

const supabaseUrl = 'YOUR_SUPABASE_URL';
const supabaseKey = 'YOUR_SUPABASE_ANON_KEY';

const supabase = createClient(supabaseUrl, supabaseKey);

const fetchData = async () => {
  const { data, error } = await supabase
    .from('your_table')
    .select('*');

  if (error) {
    console.error('Error fetching data:', error);
    return [];
  }

  return data;
};

// Example usage
fetchData().then(data => {
  console.log('Data from Supabase:', data);
  // Update your UI with the fetched data
});

This code snippet demonstrates how Replay can automatically generate the necessary code to connect to your Supabase database and fetch data. The placeholders

and would be replaced with your actual Supabase credentials. Replay can infer the table name () and the desired columns based on the interactions in the video.

Comparison with Existing Tools#

Let's compare Replay with other UI generation tools:

As you can see, Replay stands out by its ability to analyze video input and understand user behavior, leading to more accurate and functional code generation.

⚠️ Warning: Replay is still under active development. While we strive for 100% accuracy, some manual adjustments may be necessary in complex scenarios.

Real-World Use Cases#

Replay can be used in a variety of scenarios:

• •Rapid Prototyping: Quickly convert a UI mockup into a working prototype.
• •User Testing: Generate code from user testing sessions to identify usability issues.
• •Legacy System Modernization: Reconstruct UIs from video recordings of legacy systems.
• •Documentation: Automatically generate code examples from video tutorials.

Styling with Tailwind CSS#

Replay understands styling conventions and can automatically generate Tailwind CSS classes for your UI elements. For example, if the video shows a user changing the background color of a button to blue, Replay might generate the following code:

html
<button className="bg-blue-500 hover:bg-blue-700 text-white font-bold py-2 px-4 rounded">
  Click me
</button>

Replay intelligently chooses appropriate Tailwind classes based on the visual cues in the video, significantly reducing the amount of manual styling required.

Product Flow Maps#

One of Replay's unique features is its ability to generate product flow maps from the video analysis. This visual representation of the user journey helps developers understand the application's overall structure and identify potential areas for improvement. The flow maps show the sequence of screens, the actions that trigger transitions, and the data that is passed between them.

Frequently Asked Questions#

Is Replay free to use?#

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

How is Replay different from v0.dev?#

While v0.dev focuses on generating UI components based on text prompts, Replay analyzes video recordings of user interactions to reconstruct entire application flows. Replay understands behavior, not just visual appearance.

What types of video formats are supported?#

Replay supports most common video formats, including MP4, MOV, and AVI.

Can I edit the generated code?#

Yes, you have full control over the generated code. You can edit it directly within the Replay platform or download it and modify it in your preferred IDE.

Does Replay support different UI frameworks?#

Currently, Replay primarily supports React. Support for other frameworks, such as Vue.js and Angular, is planned for future releases.
