Proxy testing used to be something I avoided because it always felt complicated and unreliable. I didn’t have a tool that showed realistic results, so problems kept repeating. Everything changed after I tried online proxy checker https://proxy-checker.net/en/ and saw how straightforward it was. The results were easy to understand and actually useful. I could test large lists without any extra setup. This helped me prepare proxies properly before starting work. Since then, I’ve had far fewer unexpected issues.
