I reduced the size of my Docker image by 40% – Dockerizing shell scripts
Dive is a great tool for debugging this. I like image reduction work just because it gives me a chance to play with Dive: https://github.com/wagoodman/dive
One easy low hanging fruit I see a LOT for ballooning image sizes is people including the kitchen sink SDK/CLI for their cloud provider (like AWS or GCP), when they really only need 1/100 of that. The full versions of both of these tools are several hundred mb each

Fx – Terminal JSON Viewer
This fx rewrite is very exciting. I'll have to try it. I thought of fx as a wrapper around jq, that allowed quick iteration over building jq scripts. Sort of an Ultimate Plumber [1] but only for jq. It looks like it is now more like a JavaScript processor plus an interactive viewer.
Someone mention Visidata[2]? VisiData is also a TUI that is great on tabular data, and it can work with json. If your JSON is mostly tabular in nature, Visidata does a great job at showing that data and allowing you to explore it. A lot of json I deal with is tabular-like data. There is a great tutorial [3], that can help you get your bearings with Visidata. Once you understand those basics you might want to look at this thread [4] for what commands you can use with json.

An interactive wrapper around `jq`
Fun. But I can achieve the same result (I think) with ultimate plumber and regular jq, but without being restricted just to jq. Feel free to correct me.
