Fair warning to those who are interested. If you are the kind of person who gets lost dabbling in configuration and customisation Koreader will keep you very busy with that. Once you get past that it is very worth it if you aren't tethered to your ereader's book store ecosystem (if it has one). On my Kobo ereader it is much much faster than the default interface and has extra bells and whistles that I really appreciate.

The ability of KOReader to infer panel boundaries to do intelligent panel zoom sounds like a nice feature. I wish other Android-available comic readers could do it. I've held onto Amazon's Kindle/Comixology app for much longer than I should because intelligent panel navigation is frequently a necessity, even on my 10" tablet.

Can anyone recommend a site for buying DRM free books so I can read it with KOReader?
internet_points 4/1/2025||
https://www.libreture.com/bookshops/ has a list of stores (and for Norwegian books there is https://ebok.no/ ), but I have found no way to search "globally" (across sites like that) for DRM-free ebooks.

https://news.ycombinator.com/item?id=32442549 has some more tips.

Oh and https://bookshop.org/beta-search now actually lets you check "DRM-free" when you search, which is a very good step in the right direction!

I have a dream of https://news.ycombinator.com/user?id=marginalia_nu taking up the mantle. Though I think anyone could make something that's better than what we have now, which is nothing.

Not for buying, but for free: https://standardebooks.org

The best solution I have found is to buy a DRM book, then download the DRM-free version from libgen. That may not be what you're looking for but it keeps me in Calibre.

I've purchased a lot of mine from Kobo. There's also Standard Ebooks if you want free, high-quality reproductions of public domain works.

Note that with Kobo you need to check. I bought one there once thinking it was DRM-free, it was not.

One can also remove DRM from books one purchased with Calibre+DeDRM plugin.[0],[1],[2]

For books in German, Beam is a very good choice: https://www.beam-shop.de/

I own a Kindle Oasis 2. Amazon stopped software updates for it so I just jailbroke it and loaded KOReader. It's way better than the official software, probably the most feature-rich and customisable document viewer I've ever seen. I regret not installing it earlier.

I looked into building the emulator for KOReader and it requires CMake, Meson, and autotools... Why are 3 different build systems necessary?
arp242 4/1/2025|
It includes a bunch of dependencies as submodules and builds those as well. I haven't verified that's the reason, but I'm willing to bet a decent amount of money it is.

I used this for many years on a rooted Kobo. It was great. being able to curate my own rss feeds and have them auto fetched over wifi from calibre to the e-reader, no algorithm involved, was a glimpse at how things could have been.

I'm using KOReader with the PocketBook Era. The integration is top notch. Installation is simply done by copying the KOReader folder to the right directory on the device. After that you can set KOReader as the default reader, which means that you keep on using the original system software and library, but books will automatically open in KOReader.

This lets me use "Mail to PocketBook", Dropbox sync etc. or the fantastic Push-to-Kindle browser-plugin in combination with the fantastic KOReader. No flashing or jail break required.

How are you getting the Push-to-Kindle plugin to sync to KOReader?
vlowrian 4/2/2025||
I don’t. The plugin syncs to the PocketBook system software and KOReader is simply used as the reader application which opens the article. There is no need to sync to KOReader since it accesses the books present on my device and those are managed by the PocketBook software.
codybontecou 4/3/2025||
Ah okay, so you're using PocketBook for the syncing. I'll have to check it out. The send to kindle functionality is what keeps me coming back to the Kindle app.

If anyone is interested in helping Kavita, an open source self hosted reading software, finish off the Koreader Sync support, please take a look at this PR. It's 90% complete and just needs some finishing polish. The contributor got busy and hasn't returned for some time.

I gave KOReader a go after seeing this thread yesterday. I tried using it a year ago and gave up because the UI was so alien to me. It almost reminds me of Winamp in a sense.

But I gave it a go again and this time I spent time figuring out how to sync between devices. I've yet not synced files but here's what I got so far.

1. Koofr WebDAV for Reading Statistics sync 2. Kobo's built-in sync for progress

Both of these are free. This is a reminder mostly for myself that you need to use the service password for WebDAV access for koofr and not your koofr account's password. And make sure you save your koreader user credentials somewhere.

I'm still not happy with the keyboard situation, the koreader keyboard is ugly but I guess it's optimized for eink so that's something. I don't really type any notes into books. I mostly prefer being able to sync progress and have a centralized view of my reading statistics. And this works.

I copied all my books over manually for now, I'm happy with this. I have the following devices 1. Phone - OnePlus Open 2. eReader - Boox Tab Mini C 3. eReader - Boox Palma 1 4. Samsung Galaxy Tab S9 Ultra

Things I didn't know I needed: 1. The reading statistics. This tracks every eBook I read, and I don't have to use anything else. 2. Book map - Knowing how much time I spent in each chapter is a godsend. This really helps me understand things like this. 3. The speed reading module - perception expander - I'd never heard of this from Tim Ferris so it was new to me. I am giving it a go, and I'm not sure it's improving my reading speed but it feels like it's improving my comprehension!

Thank you to everyone who puts in the work on koreader!

I use KOReader with Koobo Clara BW (300 ppi screen), it's great.

I still have to remove a lot of CSS from most books before uploading, but after that, it is very good, as you can fine-tune every aspect and have every book look similar. Which, in my opinion, is necessary because e-ink readers still don't have enough resolution to use all the fancy fonts authors may have thought. Also, the ability to set margins to the same is very important to me.
