Fopnu is a P2P client with the same name, developed by the authors of the BitTorrent client named Tixati. Fopnu is a fully decentralized network, without indexing search results and without passing on search results to other users. Connections are made via UDP and fully encrypted.

Fopnu's customer resembles older eMule customers. In separate tabs you can view download statistics, select your own files to share, search resources shared by other users, monitor connections and downloads. The creators of the project also provided a place for a chat, where you can create channels and communicate with other users.

Thanks to this, Fopnu can also be used to exchange personal files between friends.
