What are you using for audiobook requests? I also recently setup arr stack, but I saw readarr is depreciated and there doesn't seem to be a clear successor.
Chaptarr is great! Just had their public release after a long alpha testing phase
If you don’t want to commit to one of the vibecoded no community arr clones for books then i recommend shelfmark. Lightweight grabber, easy to start with, easy to rip out later.
It’s been a while since I used it but lazylibrarian has worked for me in the past.
I tried shelfarr as well with some success a while back, but haven’t needed any new books lately since I’m busy catching up on the books I’ve downloaded (the Bible is long lol).
After reading a lot of reddit threads I settled on ReadMeABook[0] and it has been working great so far. One pretty cool feature is that it lets you connect an LLM API key and then you can have it make requests based on your library. I now have Fable 5.1 suggesting my next book.
