Headless Web Scraping

Extract data from web pages that resist simple HTTP requests — JS-rendered content, Cloudflare-protected sites, and dynamic SPAs — using scrapling's three-tier fetcher architecture and CSS-based data extraction.

When to Use

• Target page requires JavaScript rendering (SPA, React, Vue)
• Site has anti-bot protections (Cloudflare Turnstile, TLS fingerprinting)
• You need structured extraction of multiple elements via CSS selectors
• Simple WebFetch or requests.get() returns empty or blocked responses
• Extracting tabular data, link lists, or repeated DOM structures at scale

Inputs

• Required: Target URL or list of URLs to scrape
• Required: Data to extract (CSS selectors, field names, or description of target elements)
• Optional: Fetcher tier override (default: auto-select based on site behavior)
