Unlike developers of other checkers we are completely independent, i.e.: 1) we do not offer paid listing to owners, 2) we do not require a link back on listed websites, 3) we do not own any proxies. This allowed us to focus on technical aspects and develop a truely unique and innovative checking engine. The best checking engine available today. Unlike all other websites PublicProxyServers.com provides proxy list solely based on quality parameters of proxy servers (access time, life time, functionality, etc).
