Run code evaluators on your own executor

Tobias Wochinger

Self-hosted Langfuse can send code evaluators to an HTTP executor you operate.

Self-hosted Langfuse can now run code evaluators on an executor you operate. Set LANGFUSE_CODE_EVAL_DISPATCHER=external and an endpoint, and Langfuse sends each evaluation over HTTP and stores the returned scores. This lets you run code evaluators on GCP, Azure, or on premises, without AWS Lambda.

Set up the external HTTP dispatcher
