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 Langtrace if you're on a team who will stay on Starter at $0 (10k spans, 1 user) or self-host, then Growth at $39/user/month when they need cloud evals and collaboration. Skip Langfuse if you're people who only want a gateway (LiteLLM) or a framework (LangChain) without an observability SKU.
