I'm curious to see how insomnia is doing as a non-traditional startup in that he didn't "grow" the company (as far as I know). It's one of the best applications we use in our day-to-day workflow.
I've switched to Insomnia from Postman some time ago, out of frustration, and though I don't use it heavily (a few minutes every week) I really like Insomnia. There are a number of design decisions in the app that I really appreciate.
Insomnia has a better design than postman, but lack the habillity to transfer data from one request to another... So I am still with postman.
