About Langfuse
Langfuse promotes Experiments out from under Datasets, making evaluation the primary workflow.
Langfuse's recent work is concentrated almost entirely on the evaluation surface. Experiments were rebuilt as a top-level feature that runs with or without a dataset attached, and can be compared across runs over time. The LLM-as-a-Judge evaluator gained categorical scores in late March and boolean true/false scores a week later, filling out the score types beyond plain numerics. Everything else in the window is documentation or scrape artifacts.
