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 Traceloop if you're on a team who will stay on Free at $0 (50k spans, 5 seats, 24-hour retention) while they open a first Trace details, then Enterprise when they need >50k spans or on-prem. Skip Langfuse if you're people who only want a gateway (LiteLLM) or a framework (LangChain) without an observability
