I’m on calibre web automated but I’m looking to migrate away. Gets tons of features that I’m not using and I can’t keep up with. Also the slop release notes are barely readable. I put up an issue for that, not sure if it’s gonna help.

I just add a book via the web interface now and then and later download it via OPDS. Probably giving Booklore a try.
