I was using landrop before. Works fine but the GUI was just a bit off, not intuitive enough. That’s Localsend’s biggest improvement IMO.

Same for me. Smart audiobook was great on one device, audiobookshelf even better since being into selfhosting.

To answer directly, MAM is a great private tracker for many reasons, including their epub library. Bibliotik is supposed to be good but harder to get in.

For other options, have a look here.

TheOnion worthy title.
