Kobo doesn't use DRM; publishers use DRM. If the publisher publishes the eBook without DRM, Kobo sells it to you that way.

EBook stores don't determine whether DRM of employed; only publishers do.

Calibre has a GUI desktop interface, but it can also be run headless and provide a web interface. You can even run Calibre as a desktop app, and connect it to another Calibre running in server mode, and access those books as well.

As a rule, I do not like Python applications. I find them generally pootly maintained over the long term, and prone to breakage because of dependency hell. Calibre is the exception to the rule; it's an absolutely fantastic piece of software. So much so, that I donate to the project.

If the kobo hardware device can read drm'd epubs, it is "using drm" to do so. I'm asking if Calibre can read those same drm epubs. Do you know if it can, maybe by adding a plugin? I know there was something like that for Kindle files. Thanks.

Calibre doesn’t natively support reading DRMed files, but there are anti-DRM plugins which are trivial to install. You need to provide a legitimate Kindle serial number for Amazon DRM, as it uses that to de-encrypt the files. When you add the file(s) to your library, the plugin automatically runs as a file conversion. It basically converts it from a DRM-locked .epub/.azw3 to a DRM-free .epub/.azw3 instead. Since Calibre already has file conversions built in, the plugin simply uses that existing system to spit out a DRM-free version of the same file, then it adds that to your library instead.

Ah, yes. Kobo does, indeed, support DRM. Calibre does a not. You can still use non-DRM books with both.

Also, it turns out that there is a piece of software that someone built that happens to work with the very excellent Calibre plug-in system which, if you bought the eBook and have the software proof of purchase, will strip out there DRM from books and allow you to read the books with Calibre. I'm not suggesting you do that, because the unethical and corrupt DMCA bought by from crooked politicians by the media industry in 1998 stripped owners of fair use rights which they'd enjoyed until then. But, it's easy to find and trivial to use, and once you have it you tend to forget you installed it.
