This looks like something I'd use often. Thanks for creating it! For anyone who's not familiar, Anton is also behind the highly useful fx[0] for wrangling JSON data in the terminal.
I really like fx (https://github.com/antonmedv/fx) for interactive stuff. It does exactly what I think you want. You can expand individual fields and explore the schema.
However, I really do like jq for queries and scripting, so I keep both around.
In the theme of jq alternatives, there is fx[1] which has an interactive view and supports querying JSON in Javascript, Python and Ruby. It used to be a node CLI but was recently rewritten in golang[2]

I guess many people use Graylog, Splunk or similar web-based systems (which can be self-hosted if you like) and are content with that. Not sure if there are any readymade applications for using locally on your Mac.
Maybe you can hack something together with jq + Bash + awk etc?
These tools might also be useful:
