gRPC has been a pain (customization of the generated clients, automation testing, even usual testing). I haven't heard of Ezy (used BloomRPC, insomnia, and another client, all of them were an incomplete solution). I will be sure to check Ezy next time I have to use gRPC.

Some of the features I couldnt find on the gRPC apps I tried were: 1) the ability to have complete information about the request and the response, and also I couldn't add headers to the grpc request. 2) the ability to automate (run the requests without a GUI), the way newman works for postman.

I just wish gRPC would not be used on any new projects and people would use more sensible solutions.
