About Langfuse

Langfuse is an open-source observability and analytics platform purpose-built for LLM applications. It provides end-to-end tracing of LLM calls, prompt management, evaluation pipelines, and cost tracking across your AI stack. Langfuse integrates with LangChain, LlamaIndex, OpenAI SDK, and other popular frameworks.

With Langfuse, engineering teams gain visibility into latency, token usage, cost, and quality metrics for every LLM interaction. Its prompt management system enables version-controlled prompt iteration, and its evaluation framework supports both automated scoring and human review workflows.
