As a few people have pointed out, Kavita is a solid one. I ultimately used it because it saves your spot in the book server-side instead of with the browser (like calibre-web) so you can pick up where you left off on different devices.
Also has a pretty good PWA for your phone if you want to read on there.
For me, I have to do ‘url: “http://pictrs:8080/” ‘ instead of 127.0.0.1 in the config.hjson file
I also had to remove the tls line in the email section to get mine to work. I think this release is a lot more finicky regarding the config file, but it’s little idiosyncrasies don’t appear to be documented.
That being said, Lemmy is still kind of broken because I can’t even see this thread on my own instance and only see one comment on this one…
