Bruno VS Postman
Is Bruno a good alternative to Postman?Comments about Bruno as an Alternative to Postman
Ola JohanssonLooks nice, and like the simplicity with data just stored in a folder and you can sync it with git or Dropbox or whatnot.
0Postman 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.
2BlerkotronLightweight, portable, very familiar UI for ex-Postman users.

patheticcockroachBetter 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)
2blur HYIt has all features postman has, and it's modern

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