Ask HN: gRPC in 2022, Yay or Nay?

It's pretty solid. Go support is impeccable, Protobufs have lots of language support.

It's a lot easier to add features to a protobuf than to other RPC systems I've used. That's a huge advantage because your clients and server don't have to upgrade in lockstep

Yeah, gRPC is mainstream at this point -- much better to generate API clients when you can, instead of hand-rolling your own, especially as the number of engineers and teams in an organization grow.
