Thanks for the question! Insomnia is an Electron app built with with a mix of React and Elm. As an independent developer wanting to reach all platforms, Electron was basically the only option for me. And, as a web developer, it's been a super productive development environment.

The goal for Insomnia is to build a REST client that's easy to learn and a joy to use. I looked into other REST clients before starting Insomnia and found them to be cluttered and complicated. Paw was my favourite, but I needed something cross-platform so was unable to use it.
