As a general rule, I will have most of my app and system logs sent to a central log aggregation server. Splunk, log entries, even cloudwatch can do this now.

But you are right, if there is an archaic server that you need to analyse logs from, nothing beats a find/grep/sed

I have recently tried Bruno, but it lacked some basic UI features I use regularly, like file picker UI for uploading a multipart file.

I also gave Recipe Ul a look, but I did not see an option to switch environments. (Haven't installed it and tried it, just went through the docs)

So I settled on Hopsscotch. Though their desktop UI is still in alpha, it looked good to me.

Same here

No, I am trying out their desktop app.
