human-in-the-loop Prevent agents from veering off course with easy-to-add moderation and quality controls. Add human-in-the-loop checks to steer and approve agent actions. [ Add human-in-the-loop ](https://docs.langchain.com/oss/python/langgraph/interrupts) #### Build expressive, customizable agent workflows LangGraph’s low-level primitives provide the flexibility needed to create fully customizable agents. Design diverse control flows — single, multi-agent, hierarchical — all using one framework. [ See different agent architectures ](https://docs.langchain.com/oss/python/langgraph/workflows-agents) #### Persist memory for future interactions LangGraph’s built-in memory stores conversation histories and maintains context over time, enabling rich, personalized interactions across sessions. [ Learn about agent memory ](https://docs.langchain.com/oss/python/langgraph/add-memory) #### First-class streaming for better
UX design Bridge user expectations and agent capabilities with native token-by-token streaming, showing agent reasoning and actions in real time.

Use high-level abstractions or fine-grained control as needed. ![](https://cdn.prod.website-files.com/65b8cd72835ceeacd4449a53/69984e317f6e150883472ac6_logo_Elastic.svg) “LangChain is streets ahead with what they've put forward with LangGraph. LangGraph sets the foundation for how we can build and scale AI workloads — from conversational agents, complex task automation, to custom LLM-backed experiences that 'just work'. The next chapter in building complex production-ready features with LLMs is agentic, and with LangGraph and LangSmith, LangChain delivers an out-of-the-box solution to iterate quickly, debug immediately, and scale effortlessly.” ![](https://cdn.prod.website-files.com/65b8cd72835ceeacd4449a53/667b26a1b4576291d6a9335b_garrett%20spong%201.webp) Garrett Spong Principal SWE ![](https://cdn.prod.website-files.com/65b8cd72835ceeacd4449a53/69984e3163bda899d4278b90_logo_Elastic-2.svg) “LangGraph has been instrumental for our AI development. Its robust framework for building stateful, multi-actor applications with LLMs has transformed how we evaluate and optimize the performance of our AI guest-facing solutions. LangGraph enables granular control over the agent's thought process, which has empowered us to make data-driven and deliberate decisions to meet the diverse needs of our guests.” ![](https://cdn.prod.website-files.com/65b8cd72835ceeacd4449a53/667b265bed5f5a9d26d6b7d6_andres%20torres%201.webp) Andres Torres Sr. Solutions Architect ![](https://cdn.prod.website-files.com/65b8cd72835ceeacd4449a53/69984e31113abb3a098b24d7_logo_Elastic-1.svg) “As Ally advances its exploration of Generative AI, our tech labs is excited by LangGraph, the new library from LangChain, which is central to our experiments with multi-actor agentic workflows. We are committed to deepening our partnership with LangChain.” ![](https://cdn.prod.website-files.com/65b8cd72835ceeacd4449a53/6679e2d31352c6bd56c84280_ally.webp) Sathish Muthukrishnan Chief Information, Data and Digital Officer ### LangGraph
FAQs How is LangGraph different from other agent frameworks? Other agentic frameworks can work for simple, generic tasks but fall short for complex tasks bespoke to a company’s needs. LangGraph provides a more expressive framework to handle companies’ unique tasks without restricting users to a single black-box cognitive architecture. Does LangGraph impact the performance of my app? LangGraph will not add any overhead to your code and is specifically designed with streaming workflows in mind. Is LangGraph open source? Is it free? Yes. LangGraph is an MIT-licensed open-source library and is free to use. ### See what your agent is really doing LangSmith, our agent engineering platform, helps developers debug every agent decision, eval changes, and deploy in one click.
