Selfhosted

Calibre Server to host.

KOreader to install on my favorite reader and direct connect to calibre.

Pocketbook as my favorite reader.

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.

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

Calibre, Kavita or Ubooquity

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.

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

I use calibre to manage my library. Well, mostly just to put them into one place. But to browse/read/download books I've written my own service reads the calibre sqlite database and serves it as a web page. It doesn't have opds support yet, but I'm looking into that.

Calibre.

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

I manage my library on my laptop with Calibre, then replicate that to a server with Syncthing and serve it up via OPDS with COPS:

I like this because COPS is simple and easy to set up. It does just what I need and nothing else.

I read on a old jailbroken Kindle Paperwhite running KOReader.

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.

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.

Just copy to the reader?

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.

Kindle screens are very good , but eff Bezos

An iPad is versatile, but then Apple…

But FOR ME, I cannot read books on a computer screen, it is just too awkward.

So yes I iPad.

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

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