What’s the Best Proxy Tester for Checking Speed and Reliability? or How Do You Test Your Proxies? Nee

I swear by SpiderFoot for in-depth proxy testing—it’s more for OSINT but has killer proxy checks.

For quick and dirty, HideMyAss’ proxy checker works (free version has limits tho).

Features I care about:
- Uptime (obviously)
- Geo consistency (if it says US, it better *be* US)
- Speed under load (not just a one-time test)

Most free tools skimp on the last one, so I end up scripting my own tests in Python.
