    • Squid
    • Mikrotik
    • Tinyproxy
    • Litespeed
    • Varnish
    • Haproxy


Retry - Retries the check once, for each protocol separately.


If judge URL starts with 'https://' will be used for HTTPS requests, with 'http://' for HTTP, SOCKS4, SOCKS5.

Validate Field:
If not empty - Enable response validation by text which you type. Response will be valid is this string was found in response body. Also support Regexes (Regex builds through Javascript RegExp).


Swap - Swaps the judge url after each request, for acceleration and keep minimum servers busy (Will use all active proxy judges). If disabled - will use only one proxy judge with minimum response timeout.

Add new:

Url - Must be an unique.


Ip address lookup:

Url - External server, which returned your ip in a raw data. Uses for proxy anonymity detection.

Your ip address will be cached before start the checking. Lookup starts only once. If you are changed ip address, press the check button for re-lookup.


If you really no need filtering through blacklist, don't enable this feature. This feature overloads CPU, and need more time for prepare results.


Filtering - Enable filter through blacklists.

Add new:

  • Title - Must be an unique
  • Url or Path - Must be an unique

Ip addresses can be as single ( or with mask (

Blacklists loads every time before start the checking, without a progress overlay!



  • Allow - Allow only input ports
  • Disallow - Remove input ports


  • Export in protocol :// ip : port, always return proxies with protocols priority: socks5 -> socks4 -> http
  •     Example: is socks4, socks5 proxy.
        Will saved as:
  • Double click - select or deselect all countries
  • Search - may contain multi words, separated by space
