I think you can add LLM-as-judge to the self-hosted version of Langfuse by defining your own evaluation pipeline: https://langfuse.com/docs/scores/external-evaluation-pipelin...

Thanks for the pointer !

We are actually toying with building out a prompt evaluation platform and were considering extending langfuse. Maybe just use this instead.
