But that’s the literal point of WebUI of any program. To make it possible to connect and manage the program from any device from the remote machine. And there is a reason why most developers choose to use WebUI - you don’t have to create multiple cleants for every OS and every internet connected device has a web browser. In fact web browser can be considered the client in this scenario.

What could be the reason why anyone could be against WebUI? I can only think of one advantage of native client that has to be installed is that it would make of possible to associate torrent files and magnet links with it.

And lastly, if you would search for qbittorent remote client most likely in top 5 results you would find electorrent. I haven’t tried it but at least description claims that it can be used with qBittorrent.

Edit: heh it seems I managed to reply to my own comment.

He/she wants to have the web UI (the client) on a different vm/machine, as far as I understand, which is not possible at the moment with qbittorrent.

As others have said, the solution could be deluge or rtorrent.
