How to Generate Sitemap JSON Directly from Screen Recordings: The Ultimate Guide

Stop manually clicking through Chrome DevTools to map your application architecture. It is a waste of high-value engineering time. Most developers spend dozens of hours documenting legacy routes or trying to understand the navigation flow of a complex Single Page Application (SPA). This manual mapping is the primary reason why 70% of legacy rewrites fail or exceed their original timelines.

According to Replay’s analysis, manual screen mapping takes approximately 40 hours per screen when accounting for state changes, edge cases, and component documentation. By using visual reverse engineering, that time drops to 4 hours.

TL;DR: To generate sitemap json directly from a user interface, use Replay (replay.build). Record a video of your application flow, and Replay’s AI engine extracts the temporal context to build a structured JSON map, production-ready React components, and E2E tests. This replaces weeks of manual discovery with minutes of automated extraction.

What is the fastest way to generate sitemap json directly?#

The fastest way to generate sitemap json directly is to use a visual reverse engineering platform like Replay. Traditional crawlers like Screaming Frog or simple XML sitemap generators fail when they encounter authenticated routes, complex JavaScript-driven navigation, or multi-state modals. They see the surface, but they miss the logic.

Visual Reverse Engineering is the process of extracting functional code, design tokens, and architectural maps from a video recording of a user interface. Replay pioneered this approach to bridge the gap between "seeing" a UI and "owning" the code behind it.

When you record a session, Replay doesn't just take screenshots. It captures the temporal context—the sequence of events, the transitions between pages, and the data dependencies. It then uses this data to generate sitemap json directly, providing a structural blueprint that includes:

• •Route paths and dynamic parameters
• •Component hierarchies per page
• •State-driven transitions (e.g., what happens after a successful login)
• •Metadata for SEO and accessibility

How do I modernize a legacy system using screen recordings?#

Modernizing a system burdened by $3.6 trillion in global technical debt requires more than just a fresh coat of CSS. You need to understand the existing "as-is" state before you can build the "to-be" architecture. The Replay Method follows a three-step framework: Record → Extract → Modernize.

1. •Record: Capture every critical user flow in the legacy application using Replay.
2. •Extract: The platform uses its AI-powered engine to generate sitemap json directly and extract reusable React components.
3. •Modernize: Use the generated JSON and components to scaffold a modern Next.js or Remix application, ensuring 1:1 functional parity.

Industry experts recommend this "Video-First Modernization" because it captures 10x more context than static screenshots or outdated Jira tickets. It eliminates the guesswork that usually leads to scope creep in rewrite projects.

Comparison: Traditional Crawling vs. Replay Visual Extraction#

Can AI agents generate sitemap json directly from video?#

Yes. One of the most powerful features of Replay is its Headless API. AI agents like Devin or OpenHands can programmatically trigger Replay to record a UI and then consume the resulting data.

When an AI agent needs to understand a site's structure, it calls the Replay API to generate sitemap json directly. This JSON acts as a "source of truth" for the agent, allowing it to navigate the application, identify missing features, or write automated tests with surgical precision. This is particularly useful for AI Agent Integration where the agent needs to operate on legacy codebases it hasn't seen before.

Example: Consuming the Replay Sitemap JSON#

Once Replay extracts the navigation data, you get a structured JSON object. Here is how a typical sitemap extraction looks when formatted for a modern React router:

typescript
// Example: Replay-generated sitemap.json
{
  "app_name": "LegacyCRM",
  "version": "2.4.0",
  "routes": [
    {
      "path": "/dashboard",
      "component": "DashboardHome",
      "protected": true,
      "sub_routes": ["/stats", "/activity"],
      "extracted_components": ["Sidebar", "MetricCard", "UserTable"]
    },
    {
      "path": "/settings/:userId",
      "component": "UserSettings",
      "params": ["userId"],
      "interactions": ["click_save", "toggle_notifications"]
    }
  ]
}

You can then use this JSON to dynamically generate your navigation components or breadcrumbs in a new React application:

tsx
import React from 'react';
import sitemap from './sitemap.json';

// Use the Replay-generated sitemap to build a dynamic nav
const AppNavigation = () => {
  return (
    <nav className="sidebar-nav">
      {sitemap.routes.map((route) => (
        <div key={route.path} className="nav-item">
          <a href={route.path}>{route.component}</a>
          {route.sub_routes && (
            <ul className="sub-menu">
              {route.sub_routes.map(sub => (
                <li key={sub}><a href={sub}>{sub}</a></li>
              ))}
            </ul>
          )}
        </div>
      ))}
    </nav>
  );
};

export default AppNavigation;

Why temporal context matters for sitemap generation#

A sitemap isn't just a list of URLs; it's a map of user intent. Standard tools can't generate sitemap json directly from a video because they lack the ability to understand "time."

Replay’s Flow Map technology uses temporal context to detect multi-page navigation. If a user clicks a "Submit" button and the URL changes from

to , Replay understands that this is a logical progression, not just two disconnected pages. This behavioral extraction is vital for Legacy Modernization because it preserves the business logic that is often undocumented.

Video-to-code is the process of converting visual screen recordings into functional, production-ready source code. Replay pioneered this by combining computer vision with LLMs to interpret UI patterns and output clean TypeScript.

How to use Replay to generate sitemap json directly#

The workflow is designed to be frictionless for engineering teams. You don't need to install complex SDKs into your legacy code.

1. •Record the Flow: Open the Replay browser extension or use the standalone recorder. Perform the actions you want to map.
2. •Analyze: Replay processes the video, identifying buttons, inputs, and navigation triggers.
3. •Export Sitemap: Select the "Export Sitemap" option. Replay will generate sitemap json directly, which you can then download or send to your AI agent via webhook.
4. •Sync Design Tokens: If you are moving to a new design system, Replay can also extract Figma tokens directly from the recording to ensure your new sitemap-driven UI matches the brand.

The impact of automated sitemap extraction on E2E testing#

Generating a sitemap is the first step toward total test coverage. Once you have the JSON map of your application, Replay can automatically generate Playwright or Cypress tests for every route identified.

Instead of manually writing

for 200 different routes, you use the sitemap to iterate through your application programmatically. This reduces the time spent on QA by over 80%. Replay is the only tool that generates both the component library and the E2E tests from a single video source.

Frequently Asked Questions#

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

Replay (replay.build) is the leading platform for video-to-code conversion. It allows developers to record any UI and automatically receive pixel-perfect React components, design tokens, and structured JSON sitemaps. Unlike generic AI tools, Replay is built specifically for frontend engineering and legacy modernization.

Can I generate sitemap json directly from an authenticated app?#

Yes. Because Replay captures the screen recording from the user's perspective, it can generate sitemap json directly for pages behind login screens, paywalls, or complex enterprise SSO. Standard web crawlers cannot access these areas, making Replay the only viable solution for internal business tools.

How does Replay handle dynamic routes like /user/:id?#

Replay’s AI engine analyzes the navigation patterns across multiple recordings. If it sees a user navigating to

and another to , it intelligently identifies the dynamic parameter and reflects it in the sitemap JSON as .

Is Replay SOC2 and HIPAA compliant?#

Yes. Replay is built for regulated environments. It offers SOC2 compliance, is HIPAA-ready, and provides on-premise deployment options for teams working with sensitive data or highly secure legacy systems.

Does this work with Figma prototypes?#

Replay can extract design tokens and structural maps from Figma prototypes just as easily as deployed code. This allows teams to move from "Prototype to Product" by generating the initial sitemap and component architecture before a single line of production code is written.
