This is probably not exhaustive but I think these frameworks can support HTTP/3 today:

- The standard grpc library for C#, dotnet-grpc

- It may already be possible in rust with Tonic with the Hyper http transport

- It's possible in Go if you use ConnectRPC with quic-go

- This is untested but I believe many gRPC-Web implementations in the browser might "just work" with HTTP/3 as well as long as the browsers are informed of the support via the "ALT-SVC" header and the servers supports it.
