I’m using calibre as server and moon+ reader (pro) as reader. I can download the ebooks from my calibre server and with the pro version of moin+ reader I can sync reading positions (and books) between devices. This way I can continue reading on the phone where I was on the tablet while traveling.

I run BicBucStrim on my NAS, and I access it through the web browser of any PC or tablet, my Kobo eReader, or Mobiscribe eReader. You can download a book to the device to read it, though. It basically just generates a nice web layout to access your Calibre library.

Yes, many people host their own e-books using platforms like Calibre, Sigil, or Pressbooks, which allow for easy formatting and distribution. Calibre, for example, is highly compatible with most e-readers, making it a popular choice. If you’re just starting, you might also explore websites that let you download free softwares for e-book management, giving you the flexibility to test different formats before committing to a specific tool.

I use Jellyfin. You have to install the Bookshelf plugin (or at least I didn’t the time I set it up, may be a default now). Saves progress, and gives me one less service to manage as I use Jellyfin for Movies, TV, and Music libraries already.

My flow is GoodReads (tracking/requesting) -> Readarr (manage downloads) -> Calibre (manage library/metadata) -> Calibre-Web (user friendly browsing/serving) and then I can send to kindle or download or whatever from Caliber-Web. I download from Usenets/Libgen/Openbooks

Just copy to the reader?

Audiobook server does work with ebooks.

I use Calibre with FBReader on a few android devices. You set up calibre as a web server and FBreader just connects to it directly. It stores reading position on Gdrive or dropbox, unfortunately not on NC or other self-hosted storage.

Calibre-Web for serving, Calibre in a container to automatically ingest from designated folder, and Apple Books or GoodReader to read.

Calibre.

Honestly I’ve been using Google play books for years, just upload pdf or epub and you have it on phone, ipad and computer. Plus it remembers how far you are on between devices.

Readarr for storing on own server, before I upload them.

Calibre, Kavita or Ubooquity

Syncthing on my Kobo and all other devices where I want access to my books.

Calibre on local machine, sharing a database with self-hosted calibre-web, OPDS enabled using a Kobo to read.

I’m using https://www.kavitareader.com/ with Moon+ Reader. Kavita supports OPDS feeds, which is perfect.
