I threw away Audible’s app, and now I self-host my audiobooks - Ars Technica

TLDR: Audiobookshelf

Been selfhosting it for a few years. Audible is an interesting comparison and I agree with the author that ABS is superior. But it's not without its issues and challenges. Any good podcast app has vastly superior UX. That said, I'm a hoarder and I just have to store every podcast I subscribe to for some reason.
