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 Lunary if you're on a app team who will pay Team $20/user/month (or self-host the AGPL repo) to open a first Generations table — not Langfuse first unless they want that OSS trace warehouse. Skip Langfuse if you're people who only want a gateway (LiteLLM) or a framework (LangChain) without an observability
