Ever since Readarr was officially discontinued, many forks and replacements have popped up. I’m currently running pennydreadful/bookshelf, which seems to be chugging along. Faustvii/Readarr is also around but seems to not be actively meaintained??
There’s also Chaptarr, which looks promising, but I’ve heard concerns about it being vibe-coded and such (see rreading-glasses: “I do not endorse the vibe-coded Chaptarr project.”). Does anybody know to what extent this is true, and what the code quality is like?


Calibre-Web has always been interesting to me. Can it be deployed in such a way as to keep a Calibre content server also accessible? (e.g. for sync with the desktop app/Koreader/etc.)
Yep! for a while I deployed Calibre-Web alongside Calibre in a ‘books’ compose.yaml stack using Docker. I used volume mounts to expose my library to both containers. The main thing to be cautious of is that you don’t write to the db from both C and CW at the same time (which could result in corruption). Some folks spin up/down Calibre as-needed, but I had them both running and was just mindful. I personally ended up switching from C+CW to Calibre-Web Automated and fully removing Calibre. I’m able to do everything from CWA that I was doing in both previously. FWIW if you are managing devices (e.g., family, etc.), Kobo devices + Kobo sync via CW/CWA is wonderful for usability (books show up on devices ‘natively’).
Caliber web isn’t two separate applications, it’s a calibre-compatible database served via http. There is no desktop “calibre” involved.
There is integrated koreader sync, though.
