Would not choose if

  • You need LangSmith Deployment for LangGraph agents in the same product as your traces.
  • You will compare Langfuse's plan fee with a per-seat price without counting observations as units.
  • You need more than two users on the free Hobby plan. That cap is real; Core is the unlimited-user tier.
