I downloaded a bunch of proxies, but I need a quick check for survivability and anonymity. I don't want to pay for a checker if there are normal free options. Who uses free tools, can you suggest something that works?
There are free proxy checkers, but not all of them are good. It is better to choose those that can check speed, anonymity and IP country at once - it will save a lot of time. It's also useful if the checker supports bulk checking, so that you can run through the whole list at once. Sometimes free versions can give limitations on the number of proxies, but it's good for basic tasks. Here you can look at this link
