Read the LangChain pageLangChain vs Langfuse
Our take
Pick LangChain if engineers building agents in Python or JS who will read traces when something breaks. Pick Langfuse if teams shipping LLM apps who need traces and a cost tile, not another chat UI. Skip LangChain if no-code ops teams (Zapier / Make) or people who only want a visual canvas (Langflow / Dify). Skip Langfuse if people who only want a gateway (LiteLLM) or a framework (LangChain) without an observability
