Read the full guide: https://binaryverseai.com/langchain-vs-langgraph-decision-guide-framework/ Choosing the right framework decides how far your agent gets. In this 14:24 guide, we break down LangChain vs LangGraph so you can ship with confidence. Learn when a linear LCEL chain is enough, and when a stateful graph with loops, branching, and persistence wins. What you will learn: The simple difference in one line, chains for straight lines, graphs for agent brains A practical decision checklist for real projects How to move from a quick LCEL pipeline to a robust LangGraph state machine Where LangChain agents fit, and when to upgrade the runtime How LangGraph and LangSmith work together for observability and debugging Who this is for: Engineers building AI agents Python that must plan, call tools, and verify Teams choosing an AI application framework for production Builders who want fewer surprises and faster iteration Key takeaways: Use LangChain for stateless RAG, summarization, and simple tool use Use LangGraph when your app must remember context, retry, and coordinate multiple tools or roles Keep LCEL for the parts, use the graph for the brain, add LangSmith for the eyes If this saved you time, like and subscribe.
