Site Crawler & Spider

Site Crawler & Bulk Screenshot Archiver

The RootUtils Site Crawler is an advanced website analysis and archiving tool designed for developers, designers, and SEO professionals. Unlike standard screenshot tools that capture one page at a time, our Crawler acts like a search engine spider: it visits your target URL, discovers all internal and external links, and creates a comprehensive visual archive of the entire site structure.

What Can You Do With This Tool?

1. Visual Regression Testing

Before deploying a new version of your website, run the crawler on your staging environment. Within seconds, you'll have a grid of 50+ screenshots. You can instantly spot if a CSS change broke the layout on deep internal pages without manually clicking through every link.

2. Competitor Design Analysis

Want to understand a competitor's user flow? Enter their URL and select "External Links". You'll see every tool, social platform, and third-party service they link to, giving you insight into their tech stack and marketing strategy—all visually.

3. Client Project Hand-off & Archiving

Freelancers and agencies use this tool to create a "Time Capsule" of a client's website. Download all screenshots as a single ZIP file to prove the state of the website at the time of delivery, protecting you from future disputes about content placement.

Key Features

• 🕷️ Deep Spidering: Automatically extracts a full list of internal and external URLs from any HTML page.
• ⚡ Smart Queue System: Unlike tools that crash when trying to capture 100 pages, our intelligent queue processes screenshots sequentially to ensure 100% success rate without overloading your browser.
• 🎯 Selective Archiving: For large sites (over 50 pages), our "Selection Mode" lets you view the full sitemap and manually checkmark exactly which pages you want to capture.
• 🎨 High-Fidelity Capture: We use a headless Chromium engine that waits for fonts, images, and animations to load (Network Idle detection) before taking the snap. You can even scale resolution up to 4K.

How It Works

This tool leverages a serverless proxy architecture. When you enter a URL, our backend fetches the HTML and parses it for <a href> tags. It filters out duplicates and categorizes links into "Internal" (same domain) and "External". Once you start the archive process, requests are routed through a high-performance headless browser API that renders the page in a virtual environment, captures the pixels, and streams the JPEG directly to your browser.
