I’m really grateful that someone recommended proxy server checker
https://proxy-checker.net/en/ because it made my workflow so much smoother. I do a lot of GEO-based testing for mobile apps, and having the wrong proxy can completely ruin the results. With this checker, I can instantly confirm the IP’s location, speed, and privacy level. Just last week, I filtered out dozens of weak proxies that would have wasted my time. It feels good to have such a reliable tool at hand.
