It is worth pointing out that the Python implementation is particularly bad. Perhaps gRPC is really pleasant to use with Java and Go, but the Python implementation is neither usable nor stable enough for it to be worth considering its use for one's own services.

We haven't tried using gRPC in Python, as we have completely migrated from Python away towards Go.

Our experience of using gRPC in Java, C++ and Golang is pretty good. While it had some initial teething issues (when it was first released), the libraries have generally been a non-issue since the gRPC General Availability (GA-1.0 version).

If you're considering using it in Go, check out the https://github.com/grpc-ecosystem/go-grpc-middleware helper libraries that we've contributed back to gRPC Ecosystem.

Ruby too was pretty bad - more so Protocol Buffers than gRPC itself though. In my previous place, I had to fork the Ruby library and write a non-trivial amount of C code so that instances of Protocol Buffers messages could be treated as regular Ruby objects by their callers. Once I opened a PR against upstream it was quickly accepted but took some 6 months to be published to Ruby Gems. I'm not saying to stay away, but please be prepared for surprises.

My instinct would be that it'll be just inherently nicer to use in a statically-typed language.

Python can be statically typed.
