@Nate: File Transfer Potocol
If you did like OwnCloud, but missed an "admin dash" to track up/ downloads, take a look at ProjectSend here or on GitHub here. From what I have played around with it, it might not have all the bells and whistles of OwnCloud (or NextCloud), but it focusses on up/ download and is nice and small. And it has an admin dash to track activity. Then again, this is something that has php as its engine, and as many have shown, this can be a consideration/ worry on the security side. As always, it depends on your use case.
