What is Langfuse Observability
Langfuse is an open-source observability and analytics platform for LLM applications. Unlike LangSmith (which is LangChain-native), Langfuse works with any LLM framework, SDK, or custom code. It captures execution traces, manages prompt versions, collects user feedback, and provides SQL-like analytics for debugging and optimization. You can use Langfuse Cloud (managed) or self-host on your own infrastructure, giving you full control over data residency and privacy.
