According to the official Discord, “ACX has made the decision to close Booklore and step away.” Some contributors are working together on an unnamed replacement project.
For those not in the loop, Booklore was an app for selfhosting book libraries. It had a nice UI. It was able to store metadata separately from the download files, so you could have an organized library without duplication. In recent weeks, there have been conflicts about AI code, licensing, and general Discord nastiness.
RIP
Edit: The discord, website and github are all gone.
I set up Komga as soon as the original reddit thread went up about the Booklore dev. Works great, pretty simple, does what it needs to do, and setting up Kobo sync for my wife took all of 5 minutes.
