One of the creators here: We started developing Kreya a year ago when we felt some necessary GUI tooling around the gRPC ecosystem was missing. We didn't just want to create a simple gRPC client, but wanted to add powerful features such as environments/templating or global authentication configurations, so you don't have to enter the same values and configurations tediously again and again.
We're curious to hear your opinions on Kreya, so hit us with any questions or feedback!
