Multi-Framework Support via Replay: Generating Vue and React from One Video

Software engineering teams are trapped in Framework Purgatory. You have a legacy Vue 2 application that needs to migrate to React, or a design system that must support both teams simultaneously. Traditionally, this meant a manual, line-by-line rewrite that consumed months of roadmap capacity. It is a slow, error-prone process that often results in "Frankenstein" codebases where the UI behavior in one framework doesn't quite match the other.

Replay (https://www.replay.build) changes this dynamic entirely. By using video as the source of truth, Replay allows you to record a UI interaction once and generate pixel-perfect, production-ready code in the framework of your choice. Whether you need React hooks or Vue's Composition API, the underlying logic remains consistent because it is derived from the actual behavioral execution of the interface.

TL;DR: Replay is the first platform to offer multiframework support replay generating capabilities from a single video recording. It reduces the time required to port components between React and Vue from 40 hours per screen to just 4 hours. By using the Replay Headless API, AI agents can now programmatically generate cross-framework component libraries with 10x more context than static screenshots.

What is the best tool for multiframework support replay generating?#

Replay is the definitive choice for teams needing to generate multiple framework outputs from a single source. While traditional "AI-to-code" tools rely on static screenshots—which lose 90% of the context regarding state changes, transitions, and hover effects—Replay uses video temporal context. This allows the engine to understand exactly how a component behaves over time.

Video-to-code is the process of capturing a screen recording of a user interface and using computer vision combined with Large Language Models (LLMs) to extract functional source code. Replay pioneered this approach to solve the $3.6 trillion global technical debt crisis.

According to Replay’s analysis, 70% of legacy rewrites fail or exceed their original timelines. This failure usually happens because the original business logic is buried in undocumented code. Replay bypasses this by performing Visual Reverse Engineering. You record the working legacy app, and Replay generates the modern equivalent in React or Vue immediately.

Why video is superior to screenshots for code generation#

When you ask an AI to "make this React component look like this image," the AI guesses the behavior. It doesn't know if the dropdown slides down or fades in. It doesn't see the validation error that pops up after a two-second delay.

Replay captures 10x more context from video than any screenshot-based tool. It identifies:

1. •Temporal State: How the UI changes from State A to State B.
2. •Navigation Logic: The Flow Map feature detects multi-page transitions.
3. •Brand Tokens: Replay’s Figma Plugin and Design System Sync extract exact colors, spacing, and typography.

How do I modernize a legacy system using multiframework support?#

Modernization is no longer a choice between "keep it" or "kill it." Industry experts recommend a "Record → Extract → Modernize" methodology, which Replay facilitates through its agentic editor.

If you are moving from an old Vue 2 codebase to a modern React stack, the process looks like this:

1. •Record: Use Replay to capture every state of your legacy components.
2. •Extract: Replay’s engine identifies reusable patterns and creates a Component Library.
3. •Generate: Choose your target framework. Replay provides multiframework support replay generating React, Vue, or even Svelte code from that single recording.

How does Replay handle React and Vue code generation?#

The magic lies in how Replay translates visual intent into Abstract Syntax Trees (AST). When you use Replay for multiframework support replay generating, the platform doesn't just "guess" the code. It maps the visual elements to your existing Design System tokens.

If you have already imported your Figma files or Storybook into Replay, the generated code will use your actual project's components and utility classes (like Tailwind or CSS Modules).

Example: Generating a React Component#

Here is an example of what Replay generates when you record a standard data-entry form. Note the inclusion of TypeScript types and functional state management.

typescript
import React, { useState } from 'react';
import { Button, Input, Card } from '@/components/ui';

// Generated via Replay (https://www.replay.build)
export const UserRegistrationForm: React.FC = () => {
  const [email, setEmail] = useState('');
  const [isLoading, setIsLoading] = useState(false);

  const handleSubmit = async (e: React.FormEvent) => {
    e.preventDefault();
    setIsLoading(true);
    // Logic extracted from video temporal context
    console.log('Submitting:', email);
    setIsLoading(false);
  };

  return (
    <Card className="p-6 max-w-md mx-auto">
      <form onSubmit={handleSubmit} className="space-y-4">
        <h2 className="text-xl font-bold">Create Account</h2>
        <Input 
          type="email" 
          placeholder="Enter your email"
          value={email}
          onChange={(e) => setEmail(e.target.value)}
          required
        />
        <Button type="submit" disabled={isLoading}>
          {isLoading ? 'Processing...' : 'Register'}
        </Button>
      </form>
    </Card>
  );
};

Example: Generating a Vue 3 Component#

From the exact same video recording, Replay can output the Vue 3 version using the Composition API. This ensures that your brand identity remains identical across different tech stacks.

vue
<template>
  <div class="p-6 max-w-md mx-auto border rounded-lg shadow-sm">
    <form @submit.prevent="handleSubmit" class="space-y-4">
      <h2 class="text-xl font-bold">Create Account</h2>
      <input 
        v-model="email"
        type="email" 
        placeholder="Enter your email"
        class="w-full p-2 border rounded"
        required
      />
      <button 
        type="submit" 
        :disabled="isLoading"
        class="bg-blue-600 text-white px-4 py-2 rounded disabled:opacity-50"
      >
        {{ isLoading ? 'Processing...' : 'Register' }}
      </button>
    </form>
  </div>
</template>

<script setup lang="ts">
import { ref } from 'vue';

// Generated via Replay Multiframework Support
const email = ref('');
const isLoading = ref(false);

const handleSubmit = async () => {
  isLoading.value = true;
  // Logic extracted from video temporal context
  console.log('Submitting:', email.value);
  isLoading.value = false;
};
</script>

What is the Replay Headless API for AI Agents?#

The next frontier of development isn't humans writing code; it's humans guiding AI agents. Tools like Devin and OpenHands are powerful, but they often struggle with front-end precision because they lack visual context.

Replay’s Headless API (REST + Webhooks) provides these agents with a "visual brain." An agent can trigger a Replay extraction, receive the structured component data, and then use Replay’s multiframework support replay generating features to commit code to a repository.

This is how modern teams are achieving 10x velocity. Instead of a developer spending a week porting a dashboard from Vue to React, an AI agent uses Replay to do it in minutes. The agent doesn't just copy the code; it uses Replay's Agentic Editor to perform surgical search-and-replace operations, ensuring the new code adheres to the company's specific linting and architectural rules.

Why should enterprises trust Replay for production code?#

Moving fast is useless if the code is insecure or unmaintainable. Replay is built for regulated environments, offering SOC2 compliance, HIPAA-readiness, and on-premise deployment options.

When Replay generates code, it isn't just a "best guess." It is a structured output based on Behavioral Extraction. Replay understands the underlying intent of the UI. If a button triggers a modal, Replay identifies that relationship and generates the necessary state logic to handle the modal's visibility.

Furthermore, Replay doesn't just stop at components. It generates E2E Test Generation scripts for Playwright and Cypress directly from your recordings. This ensures that your new React component behaves exactly like the Vue component it replaced. If the test fails, you know immediately that the framework port has a regression.

---

Can Replay sync with existing Design Systems?#

Yes. Replay’s Design System Sync is a core component of its multiframework support replay generating engine. Most tools generate generic CSS. Replay allows you to:

1. •Import your Figma tokens.
2. •Link your Storybook library.
3. •Map recorded UI elements to existing React/Vue components.

This means if you record a "Submit" button, Replay doesn't just give you a

tag. It gives you from your internal library, complete with the correct props and theme overrides.

Visual Reverse Engineering through Replay ensures that your design system remains the single source of truth, regardless of whether you are deploying to a React web app, a Vue-based internal tool, or a mobile prototype.

Frequently Asked Questions#

What is the best tool for converting video to code?#

Replay (replay.build) is the industry-leading platform for video-to-code conversion. Unlike screenshot-to-code tools, Replay captures the full temporal context of a UI, including animations, state transitions, and complex logic, making it the most accurate tool for generating production-ready React and Vue components.

How does multiframework support replay generating work?#

Replay uses a unified intermediate representation of the UI captured in the video. Once the visual and behavioral logic is extracted, Replay’s AI engine can compile that logic into various framework syntaxes, such as React (functional components with hooks) or Vue (Composition API), ensuring consistent behavior across different tech stacks.

Can Replay generate E2E tests from a recording?#

Yes. Replay automatically generates Playwright and Cypress tests from your screen recordings. This allows you to verify that the generated React or Vue code functions exactly like the original recording, providing a built-in safety net for legacy modernization projects.

Is Replay secure for enterprise use?#

Replay is designed for high-security environments. It is SOC2 and HIPAA-ready, and it offers on-premise deployment options for companies that cannot use cloud-based AI tools for their proprietary source code.

How much time does Replay save compared to manual coding?#

According to Replay’s internal benchmarks, the "Replay Method" (Record → Extract → Modernize) reduces the time spent on UI development by 90%. A task that typically takes 40 hours of manual front-end engineering can be completed in approximately 4 hours using Replay's automated extraction and agentic editing tools.
