LangChain vs LangGraph vs LangSmith

Both LangChain and LangGraph are AI Agents Orchestration frameworks.


Basic difference is, the workflow in LangChain is Sequential and Linear, however using LangGraph AI Agents flows those are non-Linear, conditional edges, cycles, retry mechanism can be created.

LangChain can be typically used for Prototyping, simple RAG, tool-using agents.






LangGraph is best suited for Agentic RAG, multi-agent systems, review loops, complex decisioning.

LangSmith is towards debugging, monitoring, monitoring tokens, cost etc.
