Install Scrapling, pick between its HTTP, stealth, and browser fetchers, keep selectors working after a redesign, and scale up with its Spider framework.
Breaking down our census's CAPTCHA rate by vendor reveals a 16x rank-tier gradient - sharper than anything else in this series.
SHEIN has three anti-bot layers: request signing, a device fingerprint, and a device identity. How each works, and why the right path is not defeating them.
Split our 1,000,000-site tech-stack census by Tranco rank: bot management and React frameworks concentrate at the top, WordPress dominates the tail.
Install Camoufox, launch it with humanize/os/geoip config, verify the fingerprint, and see which detection layer a patched Firefox does and doesn't beat.
Beat TLS fingerprinting with curl_cffi and curl-impersonate: install, impersonate a real browser's handshake, verify it, and know what it still won't fix.
Two benchmarks and a third internal test, synthesized: engine choice, architecture, and IP-timezone coherence each failed alone against a real anti-bot target.
We ran ChromiumFish, patchright, camoufox, and zendriver against a free detector and a live Cloudflare target. All four tied — for different reasons.
We ran native and JS-patched stealth browsers through free detectors and two live Cloudflare targets. All tied on stealth — IP reputation decided pass or fail.
We joined two top-1M censuses: 12.8% of the top 100,000 sites is closed to Cloudflare's /crawl endpoint, and 29.1% of Cloudflare's own footprint.
World Cup final tickets hit $2.3M on resale, but FIFA's own platform still had 252 unsold that morning. What the anti-bot data on Ticketmaster and AXS shows.
We scanned the top 1 to 10 million sites to map how the open web defends itself: 53.5% run an anti-bot wall, 9.33% block AI crawlers, and 14.1% are dead.
Cloudflare defaults to blocking AI Agent and Training crawlers on ad-supported pages from Sept 15, 2026 — what changed and how to still collect public data.
1,000,000 sites fingerprinted: Cloudflare fronts 35.8%, WordPress runs 65.1% of every CMS site, and CAPTCHA prevalence has jumped to 16.9%.
53.5% of the top 1M sites run an anti-bot wall. How TLS/browser fingerprinting, IP reputation, and Cloudflare detect scrapers — and what still gets through.
We tracked 172.9M domains across 80 Common Crawl archives (2018–2026). About 40M are dead — but vanishing from a crawl over-counts death by about a third.
We scanned the top 1,000,000 sites: 53.5% of the reachable web runs a managed anti-bot or WAF — and, surprisingly, the busiest sites run the least.
Your scraper works locally but 403s from a server? Usually it's IP reputation, TLS fingerprinting, or headless detection — how to tell which, and fix it.
Only 14% of the top 10 million domains are genuinely dead — not the usual 27.6%. Nearly half of the 'dead' web is just blocking bots or serving errors.
Why scrapers get blocked by Cloudflare, DataDome and PerimeterX — and how to get through reliably with stealth browsers, IP rotation and clearance reuse.
We split Crawlora's tech-stack dataset by ecommerce platform: Shopify stores sit behind Cloudflare 97.5% of the time. WooCommerce stores? Just 40.6%.
