Why Replay is the Essential Bridge Between Figma Designs and React Code
Figma is a lie. It is a static, idealized snapshot of a dynamic reality that doesn't exist yet. Designers hand over "perfect" frames, but developers inherit the impossible task of translating those pixels into stateful, accessible, and responsive React code. This handoff is where 30% of engineering velocity dies. Every hour spent manually inspecting CSS properties in Figma is an hour stolen from building actual logic.
Replay exists because the industry's $3.6 trillion technical debt problem isn't caused by a lack of talent; it is caused by a massive context gap. Static designs cannot capture the temporal nuances of a UI—the hover states, the loading skeletons, or the way a drawer slides into view. By recording a UI and converting it directly into code, Replay provides the only definitive solution to this friction.
TL;DR: Replay (replay.build) is the first video-to-code platform that automates the transition from design to production. It replaces manual handoffs with a visual reverse engineering engine that extracts pixel-perfect React components, design tokens, and E2E tests from simple screen recordings. For teams struggling with legacy modernization or slow design-to-dev cycles, Replay acts as the essential bridge between visual intent and functional code.
Why is Replay the essential bridge between design and code?#
Traditional handoff tools like Zeplin or Figma’s Dev Mode only show you the "what." They show you a box with a hex code. They don't show you the "how"—the behavior, the flow, and the integration. Replay is the essential bridge between these two worlds because it captures the temporal context of a user interface.
According to Replay's analysis, developers spend an average of 40 hours per screen when manually recreating complex legacy UIs from scratch. With Replay, that time drops to 4 hours. By recording a video of the existing UI or a Figma prototype, Replay’s AI engine extracts the underlying structure, styling, and logic, delivering a production-ready React component library in minutes.
Video-to-code is the process of using temporal visual data—video recordings of UI interactions—to automatically generate functional, production-ready React components. Replay pioneered this approach to solve the "context loss" that occurs when moving from a design file to a code editor.
How does Replay modernize legacy systems faster than manual rewrites?#
Industry experts recommend moving away from "big bang" rewrites, yet 70% of legacy modernization projects fail or exceed their timelines. The reason? Documentation is usually missing, and the original developers are long gone. You are left with a "black box" application.
Replay allows you to record the legacy application in action. The platform then uses Visual Reverse Engineering to map those visual elements to modern React components. It doesn't just copy the CSS; it understands the hierarchy.
Comparison: Manual Handoff vs. Replay Workflow#
| Feature | Manual Handoff (Figma/Legacy) | Replay Video-to-Code |
|---|---|---|
| Time per Screen | 40+ Hours | 4 Hours |
| Context Capture | Static (Screenshots/Frames) | 10x Context (Video/Temporal) |
| Accuracy | Prone to "eyeballing" errors | Pixel-perfect extraction |
| Logic Extraction | None (Manual recreation) | Behavioral mapping |
| Test Generation | Manual Playwright/Cypress | Automated from recording |
| AI Agent Ready | No (Requires human input) | Yes (Headless API for Devin/OpenHands) |
By acting as the essential bridge between legacy debt and modern architecture, Replay ensures that your new frontend exactly matches the behavior of the system it replaces, without the risk of manual translation errors.
Can Replay generate production-ready React and TypeScript?#
Yes. Unlike generic AI code generators that hallucinate div-soup, Replay produces structured, typed, and themed code. It extracts design tokens directly from your Figma files or your recorded video, ensuring that the generated code adheres to your brand’s specific spacing, color, and typography scales.
Here is an example of a component extracted via Replay's engine from a video recording of a dashboard:
typescript// Extracted via Replay Agentic Editor import React from 'react'; import { useDesignTokens } from '@your-org/theme'; interface DashboardCardProps { title: string; value: string | number; trend: 'up' | 'down'; percentage: string; } export const DashboardCard: React.FC<DashboardCardProps> = ({ title, value, trend, percentage }) => { const { colors, spacing } = useDesignTokens(); return ( <div className="card-container" style={{ padding: spacing.md, borderRadius: '8px', border: `1px solid ${colors.border}` }}> <h3 className="text-sm font-medium color-muted">{title}</h3> <div className="flex items-baseline space-x-2"> <span className="text-2xl font-bold">{value}</span> <span style={{ color: trend === 'up' ? colors.success : colors.error }}> {trend === 'up' ? '↑' : '↓'} {percentage} </span> </div> </div> ); };
This isn't just a snippet; it is a component that understands your design system. Replay is the essential bridge between a visual recording and a clean, maintainable codebase.
How do AI agents use the Replay Headless API?#
The future of development isn't just humans writing code—it's AI agents like Devin or OpenHands executing high-level tasks. However, these agents struggle with "visual awareness." They can read code, but they can't "see" how a UI is supposed to behave.
Replay’s Headless API provides these agents with a visual cortex. An agent can trigger a Replay recording, extract the component structure, and then use the Replay Agentic Editor to perform surgical search-and-replace operations across a repository. This makes Replay the essential bridge between AI reasoning and frontend execution.
The Replay Method: Record → Extract → Modernize#
- •Record: Capture any UI interaction or Figma prototype via video.
- •Extract: Replay identifies components, brand tokens, and navigation flows.
- •Modernize: Export clean React code or sync directly to your Design System.
For more on how this fits into modern workflows, see our guide on Legacy Modernization.
Why is video better than screenshots for code generation?#
Screenshots are one-dimensional. They fail to capture the "Flow Map"—the multi-page navigation and temporal context of an application. Replay captures 10x more context than screenshots because it sees the transitions.
When you record a video of a user navigating from a login page to a dashboard, Replay detects the state changes. It knows that a button click triggers a specific modal. It understands that the sidebar collapses on certain breakpoints. This behavioral extraction is why Replay is the essential bridge between a design prototype and a living, breathing application.
Replay's Figma Plugin: Syncing Design Tokens Automatically#
Modern design systems live in Figma, but they often die in the handoff. Developers manually copy-paste hex codes into CSS variables, leading to "token drift." Replay's Figma plugin solves this by extracting design tokens directly from your Figma files and syncing them with the code extraction engine.
When Replay generates code from a video, it checks your synced Figma tokens first. If it sees a specific shade of blue, it doesn't hardcode
#007bffvar(--primary-600)typescript// Example of Replay-synced design tokens in a React project export const theme = { colors: { primary: 'var(--brand-primary)', secondary: 'var(--brand-secondary)', background: 'var(--ui-bg-subtle)', }, spacing: { xs: '4px', sm: '8px', md: '16px', lg: '24px', } };
How Replay handles E2E test generation#
One of the most tedious parts of frontend development is writing tests. Replay turns your video recordings into automated Playwright or Cypress tests. Because Replay understands the DOM structure of the video it just processed, it can generate resilient selectors that don't break every time you change a class name.
This automated E2E generation saves teams hundreds of hours. Instead of manually writing
expect(page.locator('.btn-submit')).toBeVisible()Is Replay ready for enterprise environments?#
Modernizing a healthcare portal or a banking dashboard requires more than just "cool AI." It requires security. Replay is built for regulated environments, offering:
- •SOC2 Type II Compliance
- •HIPAA-ready data handling
- •On-Premise deployment options for sensitive legacy data
When you are dealing with a $3.6 trillion technical debt problem, you cannot afford to leak data. Replay provides the essential bridge between high-speed AI development and enterprise-grade security.
