by Langfuse · freemium · Last verified 2026-03-17

Langfuse integrates with LlamaIndex to provide open-source observability for LLM applications. A simple callback handler captures detailed traces of query engines, retrievers, and LLM calls. This data, including token usage, latency, and custom scores, is visualized in a self-hostable dashboard for comprehensive monitoring.
