If anyone is looking for a gRPC client which will automatically resolve imports between protos and also render structured input fields for each message, check out Protocall (https://protocall.dev - disclaimer, I'm the author).

I built it to solve my biggest pain points with existing tooling like BloomRPC and gRPCurl - they were difficult to use for anything more complicated than "Hello, World". I also couldn't find any tools that would let me send protobuf-encoded requests via HTTP/1.1 rather than gRPC - there are a couple options now, but as far as I know none of them support both that and gRPC.

Grip looks super cool - it's one of the few other clients I've seen that will render structured input fields to make it easier to construct complex messages.

If you have a more urgent need for server-side streaming support, you could also check out Protocall (https://protocall.dev - disclaimer, I'm the author) - it supports all four rpc types (Unary as well as Client/Server/Bidirectional streaming), along with the structured input field rendering and automatic import resolution (via Github repo import).

I wrote it because existing tooling like BloomRPC and gRPCurl were difficult to use for anything more complicated than "Hello, World". I was also looking for tools that would let me send protobuf-encoded requests via HTTP/1.1 rather than gRPC, which didn't seem to exist at the time.
