Is there any documentation about how KotlinX RPC / Ktor / kRPC actually communicates? I don't feel I can safely adopt KRPC unless I know I can connect an application in a different language to it and understand what I'm looking for in networking logs.

Hey! kRPC is intended as a Kotlin-to-Kotlin protocol, so its internals (wire format) are unstable and undocumented for now

We also have gRPC support (pending KMP) if you need clarity on a wire level and a polyglot

Bummer. Thanks for the response!

KRPC is using websocket internally.

You guys ever consider using Wire in kotlinx-rpc? It might be a shortcut to doing gRPC with KMP.

Wire only has jvm (and android)

[jessewilson]

Our protobuf implementation runs on all platforms

[jessewilson]

Our gRPC implementation is JVM + Android

[Alexander Sysoev]

Oh, sorry, didn't realize you are a maintainer
So currently (in an unreleased yet branch), our Protobuf also does all platforms (except for android for Gradle reasons) and our gRPC is Jvm + Apple targets compatible, so there is no reason to try Wire at this point
