When a scraper starts returning CAPTCHAs or block pages, teams often blame the proxy provider first. Spoiler: replacing proxy isn\u2019t always the fix.<\/strong> In our Walmart and Amazon tests, Walmart reacted much more strongly to the browser setup, while Amazon results varied across both browsers and proxy pools without revealing a repeatable solution.<\/p>\n\n\n\n

We used NodeMaven\u2019s open-source proxy-benchmark<\/a> to compare 4 residential proxy providers across 2 browser setups. Every provider faced the same targets and request sequence during the same run, which let us see whether the result followed the browser, proxy pool, or session.<\/p>\n\n\n\n

This article breaks down the results and why a blocked scraping request should not automatically be treated as a proxy problem.<\/strong><\/p>\n\n\n

Results at a glance<\/strong><\/h2>\n\n\n\n

We counted a page as delivered only when it contained the expected search results. A CAPTCHA or block page did not pass, even when the server returned an ordinary HTTP response.<\/p>\n\n\n\n

Changing the browser improved Walmart delivery<\/td>CloakBrowser delivered 74 of 80 first pages, while Patchright delivered 0 of 80 across the same four proxy providers<\/td><\/tr>

Browser setup was the clearest observed difference on Walmart.<\/strong> Amazon varied across browsers and sampled proxy pools, but neither browser supplied a dependable fix.<\/p>\n\n\n\n

Methodology: how we compared browsers and proxy providers<\/strong><\/h2>\n\n\n\n

We ran the experiment with NodeMaven’s open-source proxy-benchmark<\/a>. The measurement tool records the browser, provider, target, session, verdict, timing, and traffic for each attempt. It also separates a website refusal from a proxy or browser error.<\/p>\n\n\n\n
