Comments about Insomnia REST Client as a Alternative to Postman
Compared to postman this is definitely better the UI is less cluttered there's Linux support, and it just looks nicer.3
More ligtweight, straightforward and intuitive.12
It's not lightweight, because still uses Electron and not native, so consuming memory alot6
Very similar to Postman, but doesn't require logging in for basic features. So useful for some quick testing.-1

Simple request chaining (right-click in the UI, no code or globals); Great workflow for when writing a fast-changing API3

Handles cookies way better than Postman2
API testing tool. Which allows web developers to create and test custom HTTP requests.

Comments about Advanced REST Client as a Alternative to Postman
Better features than Postman for my use case: I need full control over the headers, including the ability to remove them all, something which Postman doesn't allow to do (they add tons of junk headers)2
