# Langfuse

> Langfuse is an open-source LLM engineering platform designed to help developers build, debug, and optimize large language model applications

## About Langfuse

## What is Langfuse?

Langfuse is an open-source LLM engineering platform built for developers who create, debug, and optimize applications powered by large language models. It gives teams working with LLMs the visibility and tooling needed to move an AI feature from prototype to production with confidence.
What Langfuse Does
Provides observability into LLM application behavior for developers building on top of language models
Supports debugging of LLM-powered applications to identify issues in prompts, chains, or outputs
Helps optimize LLM applications over time based on observed performance
Is distributed as open-source software, allowing developers to inspect, self-host, or extend the platform
Who Uses Langfuse
Langfuse is aimed at developers and engineering teams building products on top of large language models. It fits teams that need to understand what their LLM application is doing in practice, troubleshoot unexpected or incorrect outputs, and refine prompts or application logic based on real usage rather than guesswork.
For makers shipping LLM-based features, Langfuse fits into the engineering workflow as the layer that sits between building a prototype and trusting it in production, giving visibility into how the application behaves so issues can be caught and addressed before they reach end users.
