You have to use an envoy proxy in front of your service to be able to use it for web. More infra to manage, and I don't think you get the same features as native gRPC. gRPC was designed with http2, so it's not like you can swap out the transport with websockets. There is the grpc-web project which uses HTTP1, but it sacrifices a lot of features that the http2 version offers that you might as well just use REST instead for public-facing services.
