About Langfuse
Langfuse is an open-source LLM observability and analytics platform for production AI applications. It captures traces of every LLM call in your app — inputs, outputs, latency, cost, and errors — and surfaces them in a dashboard for debugging and optimization. Evaluation features let you score outputs and run regression tests. Used by engineering teams who need visibility into how their AI apps are actually performing in production.
