Scala, Swift, Rust, C, etc. I guess with Scala you can probably use the Java one. But they have one for Kotlin...

Scala has several (approximately one per effect library): https://scalapb.github.io/docs/grpc/

That's actually cool. It's been a while since I worked on GRPC with Scala. Back then we only had that thin wrapper around Java.

Rust has tonic, which I've used to good effect as both as a client and server.

I'll second that. Using prost directly was a little rough, but with tonic on top it's been a dream

Swift is at least supported via Objective-C, and swift-grpc looks solid https://github.com/grpc/grpc-swift
