Because federation is broken between many servers, I have to use multiple accounts to see all the communities.

I’m doing my part!

running scripts like these make me nervous, especially on the host machine of a hypervisor. My (limited) understanding is that a compromised host system compromises all the VMs and containers within. Seems like you could be one command away from letting an attacker into everything.

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.
