Real-world test results : Enterprise Cloudflare vs basic CF

[abdulwadoodibnharoon]

Hey! Great library . tested Scrapling for a price aggregation system. Sharing findings for the community.

Setup

• Scrapling 0.4.7
• Ubuntu / Python 3.13
• Patchright chromium installed
• Testing from cloud

Results

Target	Fetcher	StealthyFetcher	DynamicFetcher
Love's API (JSON)	✅ 200	N/A	N/A
EIA Gov API	✅ 200	N/A	N/A
httpbin.org	✅ 200	N/A	N/A
nowsecure.nl (basic CF)	❌ 403	✅ 200	N/A
Another provider behind (enterprise CF)	❌ 403	❌ 403	❌ 403

Details

All three fetchers return the Cloudflare challenge page:

Just a moment...
Performing security verification
This website uses a security service to protect against malicious bots.

Tested with:

• StealthyFetcher().fetch(url, headless=True) → 403
• StealthyFetcher().fetch(url, headless=True, real_chrome=True) → 403
• DynamicFetcher().fetch(url, headless=True, wait_selector='[class*="rice"]', timeout=45000) → 403 (timeout)

The Cloudflare Ray IDs confirm these are challenge pages, not rate limits.

What Works Great

• API scraping with Fetcher is clean and fast
• Basic Cloudflare bypass with StealthyFetcher works perfectly (nowsecure.nl)
• CSS selector API is intuitive (page.css(), css_first())
• curl_cffi TLS fingerprinting is a real differentiator over plain requests

Suggestion

The README says Scrapling "can easily bypass all types of Cloudflare's Turnstile/Interstitial." It would be helpful to clarify this works for free/basic Cloudflare but not necessarily enterprise Cloudflare deployments. some players use enterprise-tier Cloudflare that appears to detect even Patchright.

To enable the Cloudflare solver, use the solve_cloudflare=True option with StealthyFetcher above. Also, try to read the docs 😄
