Yup, I transferred from Calibre and Calibre-Web to Grimmory end of last year. It’s a webapp based solution with built in look ups for GoodReads, Hardcover, and other services. Overall pretty nice!

It’s not fully automated, but I use Shelfmark -> Grimmory for my ebooks. Works quite nicely with the ingestion/metadata lookup in Grimmory.

I will say, even given all the drama around the original creator in the last few weeks, Booklore has a solid front end experience, is quite flexible, and generally stable app. It’s a bummer the creator acted childishly (again and again), but I know I’ll be looking to use whatever the v2 of this becomes.
