aMule currently supports Linux, FreeBSD, OpenBSD, Windows, MacOS X and X-Box on both 32 and 64 bit computers.
aMule is intended to be as user friendly and feature rich as eMule and to remain faithful to the look and feel of eMule so users familiar with either aMule or eMule will be able switch between the two easily.
Since aMule is based upon the eMule codebase, new features in eMule tend to find their way into aMule soon after their inclusion into eMule so users of aMule can expect to ride the cutting-edge of ED2k clients.
