At present, Privoxy is known to run on Win32, Mac OSX, OS/2, AmigaOS, Linux, and many flavors of Unix. There are source and binary releases for these available for download at http://sourceforge.net/project/showfiles.php?group_id=11118. But any operating system that runs TCP/IP, can conceivably take advantage of Privoxy in a networked situation where Privoxy would run as a server on a LAN gateway. Then only the gateway needs to be running one of the above operating systems. Source code is freely available, so porting to other operating systems, is always a possibility. ]]>
