Read the Langfuse pageLangfuse vs MLflow Tracing
Our take
Pick Langfuse if you're on a team shipping LLM apps who need traces and a cost tile, not another chat UI. Pick MLflow Tracing if you're on a team already on MLflow who will run Tracing locally at $0 (uvx mlflow demo or their own server) — not Weave first unless they want W&B Pro $60. Skip Langfuse if you're people who only want a gateway (LiteLLM) or a framework (LangChain) without an observability SKU.
