Inside the shared supply, real-time filtering and misleading metrics that determine whether a residential proxy network actually performs.
A residential proxy provider may advertise 150 million IPs, a 98% success rate and its own "premium" network.
None of those claims tells you whether it will work for your scraper.
Behind the marketing, providers frequently combine directly acquired IPs with third-party supply. The same addresses appear across multiple networks. An IP that works on one website can be completely unusable on another.
What separates providers may not be the pool itself, but the filtering, routing and session-management layer sitting between that raw supply and your scraper.
As NodeMaven's founder Stan Sadokov put it during our recent Reddit AMA:
Once that clicks, most of the marketing in this industry stops working on you.
Stan spent years working on browser fingerprinting and anti-detect technology at Multilogin before founding NodeMaven. During that time, he repeatedly saw apparently correct browser configurations fail because of problems at the proxy layer.
In our fifth r/WebScrapingInsider AMA, we asked Stan how residential proxy networks really work, what separates high-quality providers from weak ones and how developers should evaluate them.
Here are the nine biggest insights from the discussion.
