Hello everyone! I’m Noah from the United States, and I came across the service while preparing a spreadsheet for a website-testing project. I wanted to record different proxy types and note which locations might be useful for future checks. While gathering information, I saved source because the available categories gave me several possibilities to compare. The combination of SOCKS5, residential, mobile, ISP, and UDP proxies was what interested me first. I also noticed that location can be considered at the country and city level, with ISP information available for relevant options. I enjoyed the practical side of it because I could organize my notes around actual testing requirements instead of simply collecting random proxy addresses.
