In our blog, we'll try to give you insights into decisions and considerations that went into Kreya. We'll start by showing you how we started building Kreya over a year ago. Back then, the only gRPC GUI client was BloomRPC. It worked well, but we missed some crucial features like environments or global authentications, which made it a bit cumbersome to use. Both Postman and Insomnia, which we used for REST APIs, did not support gRPC (Insomnia has since added basic gRPC support). We decided that we should build a gRPC GUI client similar to Postman or Insomnia, which supports advanced features to make calling and testing gRPC APIs easier.
