That would require installing client software though, no?
Qbit is just a web app accessible from anything with a browser. (I keep mine behind a vpn for auth, but it’s got http form based password auth aswell.)
It does, but it feels more integrated. Clicking a magnet link or opening a torrent file is handled natively by the OS and pass it over to the native app, which talks to the Deluge server if used in thin client mode. It’s really neat.
