+1 for Bloom. The only thing it’s missing is support for the gRPC introspection API. It’s not bad if you have all of your organizations protos in one repo (which is what we do), but otherwise annoying to have to clone a repo and point Bloom at the .proto file just to talk to the API. Other tools (grpcui I believe is one) support introspection but aren’t as polished at Bloom.
