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 alot7
Very similar to Postman, but doesn't require logging in for basic features. So useful for some quick testing.0
Many of the same features as Postman, but no sync unless you pay. This is a deal breaker to developers who work on multiple computers, like home & work PCs.-5

Bruno is a new and innovative open source API client, aimed at revolutionizing the status quo represented by Postman, Insomnia and similar tools out there.
Comments about Bruno as a Alternative to Postman
Postman shut off his local client and forces you now to store your data in their cloud, also running your requests through their proxy.
It also is quite a mess to colaborate on postman colections, if you don't want to use / pay for their cloud.
With Bruno all that is not an issue at all - they work in a way which comes very natural to a developer and you can perfectly integrate your api test collections to your code repository.0
xh is a friendly and fast tool for sending HTTP requests. It reimplements as much as possible of HTTPie's excellent design, with a focus on improved performance.
