Finally! Up until now, when people ask how they are supposed to proxy grpc traffic, we could only recommend Envoy. Pretty much no one wants to hear that they have to change their stack to use new technology. Since a large part of the world is already on nginx, this was a a real barrier for adoption. Next up, browser support?

  Armeria [0] supports pretty much every possible combination of gRPC variants, including gRPC-Web - HTTP/1 and 2, TLS and cleartext, Protobuf and JSON, framed and unframed. (Disclosure: My team and I wrote it.) [0] https://line.github.io/armeria https://line.github.io/armeria

I remember seeing that Nginx has TCP proxying as well. Couldn’t that be an option?

  It is, but proxying at the higher-level protocol lets you proxy more intelligently. For example, how does a TCP proxy perform round-robin load balancing on a per-RPC basis? If it's a gRPC proxy then that capability becomes possible.

My hunch is that the impetus was largely because of this kind of conversation.
