The short version

  • Only LangGraph has a free tier, so it costs nothing to try first.
  • Each has a real cost: Datadog Logs complex, multi-tiered pricing model based on ingestion, indexing, and storage; can become expensive at scale; LangGraph steeper learning curve compared to high-level abstractions
  • They diverge on capability: Datadog Logs covers Log ingestion, LangGraph covers Human-in-the-loop controls.
