TL;DR: Replay transforms video recordings of UX design mockups into fully functional Remix web applications, bridging the gap between design visualization and production-ready code.

Static design mockups are dead. They’re a relic of a waterfall world, failing to capture the dynamic nature of modern user experiences. We need to move beyond static screenshots and embrace the fluidity of video to truly understand and translate user intent into code. Current "screenshot-to-code" tools fall short. They only see the what, not the why. This is where Replay changes the game.

The Problem with Static Mockups and Screenshot-to-Code#

Design tools like Figma and Adobe XD are powerful for creating visual representations of user interfaces. However, these static mockups often lack the crucial element of behavior. How does the user actually interact with the interface? What are the nuances of the user flow? Screenshots simply can't capture this.

Screenshot-to-code tools, while offering a seemingly quick solution, inherit the limitations of their input. They produce code that is often brittle, incomplete, and requires significant manual tweaking. They fail to understand the intent behind the design, leading to inaccurate and inefficient code generation.

Consider this scenario: a user navigates through a multi-step form in a design mockup. A screenshot-to-code tool might identify the individual form elements, but it won't understand the sequential flow, the data dependencies between fields, or the submission logic.

Replay: Behavior-Driven Reconstruction#

Replay takes a fundamentally different approach. Instead of relying on static images, Replay analyzes video recordings of UX design mockups. This allows Replay to understand user behavior, identify interactive elements, and reconstruct the underlying logic of the application.

Replay's "Behavior-Driven Reconstruction" engine leverages the power of Gemini to analyze video and generate working code. It understands WHAT users are trying to do, not just what they see. This results in more accurate, robust, and maintainable code.

Converting Video Mockups to Remix Applications with Replay#

Let's walk through the process of converting a video recording of a UX design mockup into a functional Remix web application using Replay.

Step 1: Recording the Mockup#

Use any screen recording tool (QuickTime, OBS Studio, etc.) to record yourself interacting with your UX design mockup. Make sure to:

  • Clearly demonstrate all user flows.
  • Show all interactions (button clicks, form submissions, etc.).
  • Navigate through all relevant pages and states.

💡 Pro Tip: Narrate your actions while recording to provide additional context for Replay. This can significantly improve the accuracy of the code generation.

Step 2: Uploading to Replay#

Upload the video recording to the Replay platform. Replay will automatically analyze the video and identify the key UI elements, user interactions, and application logic.

Step 3: Configuring the Remix Output#

Specify that you want to generate a Remix application. Replay offers various configuration options, including:

  • Component structure: Choose how you want the UI elements to be organized into components.
  • Styling: Select your preferred styling approach (CSS Modules, Tailwind CSS, etc.).
  • Data fetching: Configure how data should be fetched and managed.

Step 4: Generating the Code#

Click the "Generate Code" button. Replay will then use its Behavior-Driven Reconstruction engine to generate the Remix application code.

Step 5: Reviewing and Refining the Code#

Once the code generation is complete, carefully review the generated code. While Replay strives for high accuracy, some manual adjustments may be necessary.

📝 Note: Replay provides a visual interface for reviewing and editing the generated code. You can easily identify and correct any errors or inconsistencies.

Step 6: Deploying the Remix Application#

Once you are satisfied with the code, you can deploy the Remix application to your preferred hosting platform (Netlify, Vercel, etc.).

Example: Generating a Simple Remix Form#

Let's say you have a video recording of a user filling out a simple contact form in a design mockup. Replay can generate the following Remix code:

typescript
// app/routes/contact.tsx import { useState } from 'react'; import { ActionFunction, json } from "@remix-run/node"; import { Form, useActionData } from "@remix-run/react"; type ActionData = { errors?: { name?: string; email?: string; message?: string; }; success?: boolean; }; export const action: ActionFunction = async ({ request }) => { const formData = await request.formData(); const name = formData.get("name") as string; const email = formData.get("email") as string; const message = formData.get("message") as string; const errors: ActionData["errors"] = {}; if (!name) { errors.name = "Name is required"; } if (!email) { errors.email = "Email is required"; } else if (!email.includes("@")) { errors.email = "Invalid email address"; } if (!message) { errors.message = "Message is required"; } if (Object.keys(errors).length > 0) { return json({ errors }); } // Simulate sending the email console.log("Sending email:", { name, email, message }); return json({ success: true }); }; export default function Contact() { const actionData = useActionData<ActionData>(); const [isSubmitting, setIsSubmitting] = useState(false); return ( <div> <h1>Contact Us</h1> <Form method="post" onSubmit={() => setIsSubmitting(true)}> <div> <label htmlFor="name">Name:</label> <input type="text" id="name" name="name" /> {actionData?.errors?.name && ( <p className="error">{actionData.errors.name}</p> )} </div> <div> <label htmlFor="email">Email:</label> <input type="email" id="email" name="email" /> {actionData?.errors?.email && ( <p className="error">{actionData.errors.email}</p> )} </div> <div> <label htmlFor="message">Message:</label> <textarea id="message" name="message" /> {actionData?.errors?.message && ( <p className="error">{actionData.errors.message}</p> )} </div> <button type="submit" disabled={isSubmitting}> {isSubmitting ? "Submitting..." : "Submit"} </button> {actionData?.success && ( <p className="success">Thank you for your message!</p> )} </Form> </div> ); }

This code includes:

  • A Remix route (
    text
    app/routes/contact.tsx
    ).
  • A form with validation.
  • Error handling.
  • Submission logic (simulated email sending).

Replay understands the form fields, their data types, and the submission process, generating a functional Remix component.

Benefits of Using Replay#

Using Replay to convert video mockups to Remix applications offers several key benefits:

  • Faster development: Automate the tedious task of manually coding UI components.
  • Improved accuracy: Reduce errors and inconsistencies by leveraging Replay's behavior-driven reconstruction engine.
  • Enhanced collaboration: Facilitate better communication between designers and developers by providing a shared understanding of user behavior.
  • Reduced costs: Lower development costs by automating code generation and reducing the need for manual rework.
  • Increased innovation: Free up developers to focus on more complex and creative tasks.

🚀 Benefit Highlight: Replay automatically infers UI element properties (e.g.,

text
type="email"
for email input fields) from the video, saving you time and reducing potential errors.

Beyond the Basics: Advanced Features#

Replay offers a range of advanced features that further enhance the code generation process:

  • Multi-page generation: Generate code for entire applications with multiple pages and complex navigation flows.
  • Supabase integration: Seamlessly integrate with Supabase for data storage and authentication.
  • Style injection: Inject custom styles into the generated code to match your brand's design language.
  • Product Flow maps: Visually represent the user flows identified in the video recording, providing a clear overview of the application's logic.
typescript
// Example of Supabase integration (simplified) import { createClient } from '@supabase/supabase-js'; const supabaseUrl = 'YOUR_SUPABASE_URL'; const supabaseKey = 'YOUR_SUPABASE_ANON_KEY'; const supabase = createClient(supabaseUrl, supabaseKey); const saveFormData = async (data: any) => { const { error } = await supabase .from('contacts') .insert([ data ]); if (error) { console.error('Error saving data:', error); } };

⚠️ Warning: Always handle your Supabase keys securely and never expose them directly in your client-side code. Use environment variables and server-side functions to protect your credentials.
