Try audiobookshelf I use it for both audiobooks and ebooks. It has a best user management and has also mobile apps

I tried to avoid Calibre for as long as I could. In my opinion, it's way too opinionated about how everything is organized. Instead of working with you, the user, it forces you into line with how the developer thinks it should work. The developer is also kind of an ass to his community and, as a dev myself, I have some concerns over some of their choices.

All that said, I finally gave in recently and converted to Calibre because there's nothing else that works as well. It's too niche of a space for there to be much competition. To use it remotely - or, more accurately for my use, headless - the docker image I use sets up a VNC viewer to work with the application.

For actually browsing the content that Calibre organizes, I settled on Kavita. There's no competition for Calibre's organization but Kavita is easily the best content browser I've tried. If you've organized and tagged your ebooks with Calibre, it does a great job of making them available on the web and offers an OPDS server as well as the web viewer. I am more into ebooks than comics or manga but I have a few that Kavita also manages well.

I've just been down this exact journey, and ended up settling on Kavita. It has all the browse, search and library stuff you'd expect. You can download or read things in the web interface. I'm only using it for epub and PDF books, but its focus is comics and manga so I expect it to shine there.

I don't think it does mobi, but since I use Calibre on my laptop to neaten up covers and metadata before I drop books on to the server it's a simple matter to convert the odd mobi I end up with. Installation (using docker inside an LXC) was simple.

It's been a really straightforward, good experience. Highly recommend. I like it better than AudioBookshelf (which I'm already hosting for audio books) which I also tried, but didn't like as much for inexplicable reasons. I also considered Calibre-Web, but that seemed a bit messy since I guess I'd use Calibre on my laptop to manage my books on a NAS share then serve it headless from the server with Calibre-Web? I might have that completely wrong, I didn't spend any time looking into it because Kavita was the second thing I tried and it did exactly what I wanted.

Calibre-Web can be used remotely just fine...?

Calibre over Guacamole, Calibreweb, with Openbooks for usenet searching of books.

For downloading, I use Readarr or manually download from where I buy the books. A lot of the time the books I buy have DRM so I end up pirating them anyway 🤷. When readarr sends a book to calibre, it tells it to convert it so I've always got epub and mobi available.

For accessing my library, I use calibre-server, which I think comes bundled with the calibre desktop app. It's got a basic web interface for uploading, editing some metadata, and downloading; and an OPDS API which my e-reader can use to download books. If I'm outside my home network I use my VPN to access it because I don't trust calibre to be secure enough for internet exposure lol.

Don't recall why I chose this instead of calibre-web but it works fine for my purposes. I don't read comics though.

I'm currently using Calibre and Audiobookshelf, where the latter is basically just using the folder structure of Calibre with and additional folder for some audiobooks. Works okay but is not the greatest solution. The calibre library web interface is quite nice (not the weird VNC-style admin panel, the one on other port). People also mention lazylibrarian a lot but I never tried it.

I’m currently using Calibre/Calibre-Web and Audiobookshelf for podcasts and audiobooks.

I have komga running in a docker container and the tachiyomi app on my tablet for comics.

Maybe give a try to Readarr. It can download books from BitTorrent network seamlessly.
