Have people moved on from Calibre?

I've been slowly spinning up self-hosted services and Calibre was on my TODO. I haven't even heard of Booklore.

I'm wondering this too. I also thought about setting up calibre as I own a ton of drm free books and while the calibre reader itself is nice (the viewer is all I mainly use), sometimes I do find myself wanting to read on my phone while at a dr appointment or whatever
