Ask HN: Any Good Fuzzer for gRPC?

I have been using Schemathesis (https://github.com/schemathesis/schemathesis) for some time to test REST APIs and I have found it amazing. I love the ways it find unexpected bugs and it really help me have more confidence in my systems.I also love how it integrate directly with pytest but that's more of a cherry on the cake.

But now I am working with GRPC service I can't find anything similar. The few solutions I found are closed source and necessitate to integrate with 3rd party platforms.I found that strange as GRPC as RPC seem perfect for fuzzing.

Did I miss a great tool that you use?
