aMule is an eMule-like client for the eD2k and Kademlia networks, supporting multiple platforms.
Currently aMule (officially) supports a wide variety of platforms and operating systems (Windows, Mac OS X, Linux…), being compatible with more than 60 different hardware+OS configurations.
aMule is entirely free, its source code released under the GPL just like eMule, and includes no adware or spyware as is often found in proprietary P2P applications.
