Ripping myself is what I did with Libation as suggested here. You log into your audible account when starting the software for the first time, your libary is shown and you can start to download.

When adjusting the auto tagging then audiibookshelf automatically sorts the stuff in the correct way with series etc.

Perfect combination and totally free.

Not for ripping but to serve your books and for the selfhosters among us use audiobookshelf.

Really great piece of software

Proxmox

Edit: Installed as the hypervisor on bare metal and then whatever you want to try out like OMV, Plex, jellyfin, syncthing or cloud software in an LXC or VM
