OpenNap was an open-source Napster server, extending the Napster protocol to allow sharing of any media type, and adding the ability to link servers together. It became popular after the original Napster network was shut down in 2001, but was subject to similar pressures and its use soon declined. As of 2024, the WinMX client is the only one still in use.

== History == The original Napster peer-to-peer file sharing service was a protocol which allowed users to transfer files directly between their clients. The protocol was reverse engineered by a developer nicknamed Drscholl and several other programmers. The first OpenNap servers appeared in 1999, operating in the same manner as Napster servers did. A client program connects to a centralized OpenNap server, search for, share and download files. The OpenNap server keeps track of all available files and provides clients the ability to search the index of available files and initiate a direct transfer between the clients. The files available via OpenNap servers are stored on the clients, never passing through the server. In addition, instant messages (private chat) and group chat services similar to IRC were also available.
