Prometheus remote write libs?

Hello,

I am trying to build a small POC thats able to receive, process and produce prometheus remote write metrics (prompb).
I see lost of libraries for instrumenting code not but for handling or generating remote write events.

Does anyone know of any currently available libs?

Just for the record for other the only thing I have found if this one but its in Erlang: GitHub - getkimball/cortex_remote_write: Erlang library to forward Prometheus metrics to a Cortex/Prometheus instance
