Have you looked into goa design[1]? You define your services with a contract via their DSL and it generates all code for you as well; has some nice validation options out of the box. - similar to grpc gateway you just need to conform to the generated code’s service interface. I believe it supports, http, websocket and grpc. [1]https://github.com/goadesign/goa https://github.com/goadesign/goa
