What’s the Best Checker Proxy for Reliable and Fast Results? or How Do You Verify if a Checker Proxy

Check out FreeProxyLists.net—it’s hit or miss, but their checker proxy tool lets you filter by speed and uptime. I’ve found some gems there.

To test, I use a simple bash one-liner: `curl -x <proxy> ifconfig.me`. If it returns the proxy’s IP, you’re good.

Also, make sure your proxy isn’t blocked by the site you’re testing. Some sites blacklist known proxies.
