Langfuse

Langfuse is an open-source AI tool designed for developers building complex LLM (Language Model) applications. It offers detailed production traces and analytics to help trace, debug, and improve the performance of LLM apps.

• Observability: Detailed production traces provide a granular view of quality, cost, and latency for LLM apps
• Data tracking: Track non-LLM actions such as database queries and API calls for optimal issue visibility
• Prebuilt analytics: Gain insights into important metrics related to cost, quality, and latency to improve LLM app performance
• Integrations: Integrate with any LLM app using the Langchain integration or Langfuse Client SDKs for easy trace capture
