Data Scope

Clean Content vs Discarded Noise

SpectraCrawler runs full headless Chromium to evaluate JavaScript, but extracts only clean text and valid links while stripping layout and tracking clutter.

What Gets Extracted

  • Page Titles & Meta Context Captures document title, canonical target URL, and timestamped crawl logs.
  • Readable Text Hierarchy Headings (H1–H6), body paragraphs, article text, bullet lists, and table rows with layout spacing preserved.
  • Resolved Hyperlinks All internal and external anchor tags resolved to full absolute URLs with clean descriptive text.
  • Standard Output Files Clean A4 PDF reports, plain UTF-8 text files, and bulk ZIP archives.

What Gets Stripped Out

  • Media & Visual Assets Images, banners, SVG paths, video embeds, and web fonts are blocked before download.
  • Scripts & Telemetry Trackers Google Analytics, Meta Pixels, DoubleClick, and ad network telemetry scripts are aborted.
  • Stylesheets & Layout Clutter Inline styles, CSS classes, cookie notices, and layout wrapper tags are completely removed.
  • External Domain Straying Deep crawl mode locks strictly to the target domain, preventing external loops.

FAQ

Frequently Asked Questions

Have questions about SpectraCrawler? Find quick answers here about dynamic web crawling, PDF generation, page limits, and web safety.

SpectraCrawler is a headless-browser utility designed to crawl dynamic and static websites. By running a real Chromium instance, it executes JavaScript to extract pure content and links, exporting them directly to clean, structured PDF files.

Unlike basic HTML parsers, SpectraCrawler uses Puppeteer to render websites like a real user. It waits for network activity to settle, allowing React, Angular, Vue, and Next.js applications to load their content before extracting the data.

SpectraCrawler supports deep multi-page crawling (same-domain restricted) up to 300 pages per crawl. The results are packaged into a zip file containing separate PDF documents for each crawled page.

Absolutely. SpectraCrawler is a developer utility that extracts public visual text and links. It ignores scripts, tracker cookies, styling, and media assets, compiling pure information into readable, print-ready reports.

No. SpectraCrawler is built to index public-facing layouts responsibly. It does not bypass login screens, authentication gates, paywalls, or CAPTCHA triggers, focusing entirely on publicly accessible web pages.

Single Page mode processes only the specific URL provided. Deep Crawl mode identifies all internal links on the initial page and automatically visits them recursively (up to 300 pages), packaging the resulting PDFs into a single ZIP file.
