Definition
Langfuse is an open-source LLM engineering platform designed for tracing, monitoring, and evaluating RAG pipelines and AI agents. It provides developers with deep visibility into complex, multi-step LLM workflows by capturing spans, tracking token costs, and managing prompt versioning, though it introduces a minor telemetry latency trade-off for the benefit of system auditability.
A specialized observability and analytics suite, not a model orchestration library like LangChain.
"An 'Air Traffic Control Black Box' that records every decision, communication, and coordinate of an AI agent's flight path for post-mission analysis."
