A few libraries in the Java world have this model. They haven't produced unicorns but seem to be pretty stable businesses - jOOQ(1), hibernate(2) etc. I'm researching DB libraries for work and so those are the ones I recalled immediately, but I think there are some commercial UI ones too.

Sidekiq [0], as well. Though that's a Ruby background processor.

Graphql.pro is a paid library for ruby as well.
