How is Matrix dysfunctional?

Setting up Matrix/Synapse was extremely easy and done in a day. The self hosting part is not that hard and I would say migrating users would be the majority of your time. Plenty of VPSs online make obtaining infrastructure very easy.

Are you self hosting? I just set up an instance today and it was extremely easy following the instructions for the ESS Community edition on github.

Borg Base offers EU based server locations. They have been awesome to work with.

I simply use both. New book comes in, add to Calibre to get most metadata down pat and move to my library, then gets imported into Booklore where I can easily make minor changes/fixes and that’s it. I use Booklore for reading across many of my devices.

You could get rid of Calibre in my stack, I just find it nice for local management on my host PC.
