Our take
Pick Formbricks if product teams who will stay on Hobby $0 (1 workspace, 250 responses/month, no card) while they ship a first link survey, then buy Pro at $89/month when they need 2,000 responses, 3 workspaces, and contact segments. 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)
