I got an instance up and running (obligatory Ansible role https://codeberg.org/ansible/audiobookshelf) and added my audiobooks library to it. Looks very nice :-)

My initial impression is that the audiobooks UX is much better than that of Jellyfin. I will definitely be moving that library to Audiobookshelf.

Podcasts can only be added and episodes downloaded for users with admin privileges, which seems excessive to me. But given that, the UX is straight-forward. Supports OPML import, and handled my OPML file with almost 150 feeds without choking.

In summary, I am happy to have it up and running and expect it to be my primary venue for audiobook and podcast listening.
