I've used neither packages.
I was suggested by my team lead to look at pii-anonymizer (https://github.com/thoughtworks/pii-anonymizer) for anonymising some of our data while it is being exposed through a REST API. I was wondering whether gonymizer (https://github.com/smithoss/gonymizer) is a suitable Go alternative.
If not, and if you know of any Go alternative to pii-anonymizer, kindly recommend one.
