For the client I use a simple go -> c++ compiler I wrote and compile to wasm from that actually, on my side projects. It had zero overhead interfacing to / calls to C/C++ (including generics<->templates) since it's just generating that. Example web game made with that: https://github.com/nikki93/raylib-5k

I think I've seen wasmtime before. If I needed to interface to any C/C++ things on the server I would probably just write in C/C++ (or Gx) yeah.
