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.
