this is the first meme I have ever made (yes I am that old) - so be gentle :) what does being modern mean to you?

What do you mean by modern api client? Postman? Try bruno.

this is the “joke”. that every API client calls themseleves modern without this essentially meaning much. and certainly not, I dont mean Postman. But this is the easy answer. What I also mean is that many of the tools that came as a response to Postman being “old fashioned” are basically mimicking the same things or principles with a few things here and there. so everything is like “postman but with a better XYZ feature” or “Postman but open source”…

Bruno does not have any of the characteristic in the meme you shared. And still I do not understand what do you mean by modern api client. Every single application using an API is an API client. Do you mean stuff like curl or postman or things like first party SDKs or what?
