By LangfuseLangfuse is an open-source (MIT) AI engineering platform for observability and evaluation of LLM applications and agents: tracing of every model call, tool call and retrieval step, evaluations with LLM-as-a-judge or human review, prompt management, a playground, experiments, and cost and latency dashboards. It can be self-hosted or used as a cloud service.
