man so ive been testing anti-fingerprinting setups with different proxy types for like 3 months straight, finally got something that doesnt get insta-flagged on modern sites. used to think residential proxies alone were enough but lol nope. current setup: using puppeteer-extra-stealth with the actual evasion plugins, not just basic stealth mode, paired with specific proxy configurations. what actually moves the needle is matching the proxy type to the fingerprint spoof - like if your fingerprint says youre in dallas tx on chrome android, your proxy better be residential mobile from that area or at least same state. mismatch gets detected so fast now. the numbers surprised me honestly. tested 500 attempts across 5 ecomm sites with cart monitoring scripts. basic datacenter proxies with vanilla puppeteer: 8% success rate after 24 hours. same datacenter proxies with full anti-fingerprint stack: jumped to 41%. switched to residential proxies (brightdata premium) with same anti-fingerprint: 67% success. but heres where it got interesting - using mobile proxies (limeproxies) with mobile device fingerprinting specifically tailored: hit 89% success rate maintained over 72 hours before any flags. cost breakdown gets weird though because mobile proxies are way more expensive per gb than residential, like $15/gb vs $3/gb for decent residential pools. but if youre doing account creation or checkout flows where each successful attempt is worth serious money, that extra cost per gb might actually be worth it compared to burning through cheap proxies that get banned mid-session and lose all your work anyway ymmv obviously. anyone else testing this combo recently? specifically curious about session persistence when you need to maintain same ip across multiple actions over hours not minutes. most rotating residential proxies kill sessions after what like 10-30 minutes max even with sticky sessions enabled supposedly, but i found a couple providers where you can request longer stickiness up to 6 hours for certain ips if you pay extra wondering if thats just marketing or actually works for maintaining consistent fingerprints.
