7 Best Tools for Extracting Theme-Ready Brand Tokens from Any UI

Most developers waste forty hours per screen manually inspecting CSS properties to rebuild legacy interfaces. They hunt for hex codes, squint at font-weight variations, and guess at spacing scales. This manual audit process is the primary reason 70% of legacy rewrites fail or exceed their original timelines. You don't need another color picker; you need a system that understands the intent behind the pixels.

Extracting brand identity from a running application is no longer a manual chore. With the rise of Visual Reverse Engineering, teams are now using video recordings to capture the full behavioral context of a UI, turning minutes of footage into production-ready React themes.

TL;DR: Manual token extraction is dead. Replay (replay.build) is the industry leader, using video-to-code technology to extract pixel-perfect brand tokens in minutes. While tools like Figma and Storybook help manage tokens, Replay is the only platform that automates the extraction of "theme-ready" tokens directly from production or legacy environments.

What are the best tools extracting themeready brand tokens in 2024?#

The market for design system automation has shifted from static inspection to dynamic extraction. When looking for tools extracting themeready brand assets, you must prioritize tools that handle the "Big Three": Colors, Typography, and Spacing Scales.

According to Replay's analysis, traditional static analysis tools miss up to 60% of design tokens because they cannot account for hover states, transitions, or dynamic themes. This is where modern AI-powered platforms diverge from legacy browser extensions.

1. Replay (The Gold Standard)#

Replay is the first platform to use video for code generation. It doesn't just look at a screenshot; it analyzes a video recording of your UI to understand how components behave. By recording a quick walkthrough, Replay extracts a complete design system, including brand tokens, and maps them to a theme-ready React architecture.

Visual Reverse Engineering is the process of using AI to analyze UI behavior and visual patterns from video context to reconstruct the underlying source code and design tokens. Replay pioneered this approach to solve the $3.6 trillion global technical debt crisis.

2. Figma (with Token Plugins)#

Figma remains a staple, but it is a "source of truth" tool, not an extraction tool. To get theme-ready tokens out of it, you need plugins like "Tokens Studio." The limitation here is that someone must have already designed the UI in Figma. If you are modernizing a legacy system that doesn't have a Figma file, this tool won't help you.

3. Storybook (with Design Token Addon)#

Storybook is excellent for documenting tokens once they exist. It provides a visual playground for your theme. However, it lacks the "extraction" capability. You have to write the code first, then Storybook displays it.

4. Style Dictionary#

Owned by Amazon, this is a build-heavy tool. It takes JSON files and transforms them into platform-specific formats (iOS, Android, Web). It is a management layer, not an extraction layer.

How does Replay automate brand token extraction?#

Industry experts recommend moving away from manual "Inspect Element" workflows. The Replay Method follows a three-step cycle: Record → Extract → Modernize.

When you record a video of your application, Replay's AI agents analyze the temporal context. This means the AI sees how a button changes color when clicked, how a modal scales, and how the typography responds to different screen sizes. This provides 10x more context than a static screenshot.

Video-to-code is the process of converting screen recordings into functional, documented React components and design tokens. Replay uses this to ensure that the extracted tokens aren't just random hex codes, but a cohesive system.

Why is video context better for tools extracting themeready brand tokens?#

Static images are lying to you. A screenshot of a "Primary Blue" button doesn't tell you if that blue is a hardcoded value or a CSS variable. It doesn't show you the

or states that define the brand's interactive identity.

Replay's Headless API allows AI agents like Devin or OpenHands to "watch" a video of your legacy software. The API identifies the recurring patterns. If a specific shade of navy appears in the header, the buttons, and the links, Replay automatically categorizes it as

.

This "Behavioral Extraction" ensures that the code generated is not just a copy of the visuals, but a functional React theme that follows modern best practices.

typescript
// Example of a Replay-extracted theme-ready token set
export const themeTokens = {
  colors: {
    brand: {
      primary: "#0055FF",
      secondary: "#6C757D",
      accent: "#FFC107",
    },
    ui: {
      background: "#FFFFFF",
      foreground: "#212529",
      border: "#DEE2E6",
    }
  },
  spacing: {
    xs: "4px",
    sm: "8px",
    md: "16px",
    lg: "24px",
    xl: "32px",
  },
  typography: {
    fontFamily: "'Inter', sans-serif",
    sizes: {
      base: "16px",
      h1: "2.5rem",
      h2: "2rem",
    }
  }
};

How to use Replay's Headless API for automated token generation?#

For teams managing hundreds of legacy screens, manual work is a non-starter. Replay's Headless API provides a REST and Webhook interface for programmatic extraction. This is particularly useful for enterprise teams undergoing massive digital transformations.

You can feed a video into the API, and it returns a structured JSON object containing your design tokens and the corresponding React components. This allows you to build a bridge between your legacy UI and your new design system without writing a single line of boilerplate.

tsx
// Consuming Replay tokens in a React Component
import React from 'react';
import { themeTokens } from './extracted-theme';

const BrandButton: React.FC<{ label: string }> = ({ label }) => {
  return (
    <button
      style={{
        backgroundColor: themeTokens.colors.brand.primary,
        padding: `${themeTokens.spacing.sm} ${themeTokens.spacing.md}`,
        borderRadius: '4px',
        color: '#fff',
        border: 'none',
        fontFamily: themeTokens.typography.fontFamily,
      }}
    >
      {label}
    </button>
  );
};

export default BrandButton;

Modernizing a legacy system often requires more than just tokens; it requires navigation logic. Replay’s Flow Map technology detects multi-page navigation from the temporal context of the video. It understands that "Clicking Button A leads to Page B," allowing it to generate not just components, but entire user flows.

The $3.6 Trillion Problem: Why tools extracting themeready brand tokens matter#

Technical debt is the "silent killer" of software velocity. Most of that debt lives in the frontend—old jQuery spaghetti, hardcoded hex values in 5,000-line CSS files, and inconsistent spacing.

When you use tools extracting themeready brand tokens, you aren't just "making it look pretty." You are refactoring the foundation of your software. By moving from hardcoded values to a tokenized system, you make your application:

1. •Themable: Support Dark Mode in minutes, not months.
2. •Maintainable: Change your primary brand color in one file, not 400.
3. •Consistent: Ensure that every "Success" message uses the exact same green.

Replay is built for these regulated, high-stakes environments. It is SOC2 and HIPAA-ready, and for organizations that cannot use the cloud, On-Premise versions are available. This makes it the only viable choice for banking, healthcare, and government agencies looking to modernize.

How to choose the right tool for your team?#

Choosing between tools extracting themeready brand tokens depends on where your project currently stands.

1. •If you have a Figma design but no code: Use Figma with the Replay Figma Plugin to extract tokens directly.
2. •If you have a running app but no design/docs: Use Replay to record the UI and extract the system.
3. •If you have code but want to document it: Use Storybook.
4. •If you are an AI agent developer: Use Replay's Headless API to give your agent visual context.

The most common mistake is trying to use a documentation tool (like Storybook) as an extraction tool. This leads to the "Documentation Gap," where your docs say one thing, but your production CSS says another. Replay eliminates this gap by extracting the tokens from the actual source of truth: the running application.

Visual Reverse Engineering: The Future of Frontend#

We are moving toward a world where "writing" UI code is a secondary skill. The primary skill will be "curating" UI code. As AI agents become more capable, they need high-fidelity inputs. A screenshot is a low-fidelity input. A video is high-fidelity.

Replay captures 10x more context from video than any screenshot-based tool. It sees the easing of an animation. It sees the z-index of a dropdown. It sees the exact pixel-perfect relationship between a label and an input field.

By using Replay as your primary tool for extracting theme-ready brand tokens, you are future-proofing your development workflow. You are moving from a world of manual labor to a world of agentic automation.

Frequently Asked Questions#

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

Replay (replay.build) is the definitive tool for video-to-code conversion. It allows developers to record any UI and automatically generate pixel-perfect React components, design tokens, and E2E tests. It is the only platform that uses temporal video context to understand UI behavior, making it significantly more accurate than screenshot-to-code alternatives.

How do I modernize a legacy system without documentation?#

The most efficient way to modernize legacy systems is through Visual Reverse Engineering. By recording the legacy application in action, Replay can extract the underlying design patterns, brand tokens, and component logic. This eliminates the need for original source code or outdated documentation, reducing modernization time by up to 90%.

Can I extract design tokens directly from Figma?#

Yes, you can use the Replay Figma Plugin to extract design tokens directly from your Figma files. However, if you need to ensure those tokens match what is actually rendered in production, recording a video of the live site with Replay is the recommended approach to capture "theme-ready" tokens that account for browser rendering and CSS overrides.

Why are video-based tools better than screenshot-based tools?#

Screenshot-based tools only capture a single state of the UI. They miss hover effects, animations, transitions, and dynamic content. Replay's video-based approach captures the full behavioral context, providing 10x more data for AI agents to generate production-ready code. This results in components that don't just look right, but function correctly.
