Langfuse + LlamaIndex

by Langfuse · open-source · Last verified 2026-03-17

Langfuse's open-source observability platform integrates natively with LlamaIndex via a one-line callback handler, capturing traces for every query engine, retriever, and LLM call. The integration surfaces token usage, latency histograms, and custom evaluation scores in a self-hostable dashboard.
