 "what": "Langfuse is an open source LLM engineering platform for developing, monitoring, evaluating and debugging AI applications. It traces LLM calls, retrieval and agent steps, manages and versions prompts, runs evaluations with LLM-as-a-judge, code evaluators and user feedback, keeps datasets for testing, and offers a playground and a full API. It can be self-hosted with Docker Compose in minutes or used as a managed cloud.",
