FriendNet is self-hostable, open source file sharing for friends, like a mini-Soulseek. Unlike Soulseek and other P2P networks, port forwarding is optional!

You can host a private room for your friends or group to share folders on their computers, create profiles, and search files.

For those familiar with BitTorrent, hosting your own FriendNet server can be compared to owning a private tracker.
