Delicious Library 3/Librarian Pro alternatives

[cuestakid]

I have started looking for an alternative to the apps like Delicious Library 3/Librarian Pro that are cloud based, ideally with online lookup abilities for all kinds of items (not just movies/games/books/music). Has anyone come across any tools like this, or is something like Amazon lists where I have to put all items back in manually the best option.

Collection database software for movies, books, music, comics and games

Catalog your collection of CDs and vinyl records, DVDs and Blu-rays, books, comic books or video games. Use the Connect web-based software, install the CLZ mobile app on your iPhone, iPad or Android device, or use the downloadable Collector software on your Windows computer.

but is web based. They discontinued their Mac App.

I have seen them but I want to add other things like electronics and other items. Collectorz gets 3/4 of the way.

I totally whiffed seeing that Delicious Library3 was being discontinued, despite having it since its first version, and got unpleasantly surprised when I was trying to scan in a CD.
Any suggestions for a MacOS replacement app that
- Is NOT cloud-based?
- Definitely works for CDs; ideally for DVDs as well
- Is proprietary (that is, I don't have to pay a perpetual license fee)
- I can import Delicious Library 3 content into?
I have ~1800 CDs, and I really, really don't want to have to scan them all in again...

I've been wandering around the Internet and using sites like "AlternativeTo" and so far about the only one that looks about right is Numento. Any thoughts?
