Speed is everything. Ensure your checker supports multi-threading (testing multiple proxies at once). A single-threaded checker will take hours to process a large list.

  • Store results with timestamps; mark stale items for re-checking.
  • Provide export and simple UI/CLI for filtering by country, latency, protocol, anonymity.

    • Not all tools are created equal. The best solutions share these characteristics:

    Trying to use an HTTP proxy for HTTPS traffic. Solution: Always check both protocols and separate them in output.

    Finding proxies is only half the battle. Most free proxies die within hours or are simply too slow to use. A Proxy Checker (or Proxy Judge) is a tool that tests your harvested list to see which ones actually work.
