Pick Confident AI if aI teams who will pay Starter so more than 5 test runs a week and 1 GB-month of traces sit on one project. Pick Langfuse if teams shipping LLM apps who need traces and a cost tile, not another chat UI. Skip Langfuse if people who only want a gateway (LiteLLM) or a framework (LangChain) without an observability SKU.
