The short version

  • Only LangChain has a free tier, so it costs nothing to try first.
  • Each has a real cost: LangChain the free Developer plan of LangSmith is limited to 1 seat; RunPod idle volume disk storage is billed at $0.20 per GB per month, double the $0.10 per GB per month charged while the pod is running
  • They diverge on capability: LangChain covers Chains and agents, RunPod covers GPU instances.
  • Prices and features above were last checked on 30 August 2026.
