Five scraping and browser-automation repos, each already tested against its own specific claim — not the same claim, so this list doesn't pretend they compete head-to-head. Four are about getting clean, usable data out of a page. One is about not getting blocked while you try.
Why these 5
This covers the actual stages of scraping AI-adjacent data: rendering a real browser (browser-use), stripping a page down to clean text (trafilatura), letting an LLM decide what to extract (Scrapegraph-ai), turning a page into LLM-ready markdown (crawl4ai), and evading bot detection when a site fights back (HeadlessX). That last one is tested against a different question than the other four — does it get past detection, not is the extracted output clean — and its entry below reflects that directly from its own review, not a rewritten version of the others' framing.
