QScrape

QScrape is a web scraper evaluation suite that provides a collection of fictional test websites across multiple difficulty levels, designed for benchmarking and testing the capabilities of web scrapers.

Difficulty Levels

  • L1, Static HTML/CSS/JS: Standard sites with no dynamic data and no web frameworks.
  • L2, Modern Frameworks: Sites built with Svelte △, React ○, Vue ◑, and Solid ◇, covering the DOM-level complexity typical of real-world SPAs.
  • L3, Anti-Bot: Sites that actively resist automated access with rate limiting, fingerprinting, session enforcement, and obfuscated markup.

Using QScrape with VoidCrawl

QScrape sites are ideal targets for testing VoidCrawl’s browser automation. Point VoidCrawl at any QScrape URL to validate that your CDP-driven scraping pipeline correctly renders and extracts content from known, stable sources, without hitting live sites.

L3 anti-bot sites are particularly useful for validating VoidCrawl’s stealth mode and session handling before deploying against real targets.

FAQs

Can I use QScrape sites with VoidCrawl?

Yes. Point VoidCrawl at any QScrape URL to validate that your CDP-driven scraping pipeline correctly renders and extracts content from known, stable sources.

Do QScrape L3 sites require a headless browser like VoidCrawl?

L3 sites apply anti-bot techniques that often require full browser rendering. VoidCrawl’s CDP-based automation handles JavaScript execution, session cookies, and request-header fingerprinting out of the box.

Are QScrape sites suitable for production scraping?

No. They are fictional test targets designed for evaluation and benchmarking, not for collecting real data.

What is the difference between L2 and L3 sites?

L2 sites add framework complexity (React, Svelte, etc.) but make no attempt to block scrapers. L3 sites actively apply anti-bot techniques such as rate limiting or obfuscated markup.
