Gnutella does not run as a single, standard client software. Instead, it runs as a series of diverse clients that all support the general Gnutella protocol. Examples of clients that run on this protocol include:
Bearshare
Gnucleus
Morpheus
Each of these programs allow file sharing of a multitude of types, including MP3s, video files, films, games, photos, documents, and software, to name a few. LimeWire works in Windows, Mac, and Linux/Unix environments; however, most Gnutella clients run only in Windows and Linux/Unix. Each of these programs offer a free version of their software.

KaZaA, another well known P2P file sharing program, does not use the Gnutella protocol; however, it works in the same fashion.
