LangGraph FAQs

  • Do I need to use LangChain to use LangGraph? What’s the difference?

    No. LangGraph is an orchestration framework for complex agentic systems and is more low-level and controllable than LangChain agents. On the other hand, LangChain provides a standard interface to interact with models and other components, useful for straight-forward chains and retrieval flows.

  • 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.

  • Is LangGraph Cloud open source?

    No. LangGraph Cloud is proprietary software that will eventually be a paid service for certain tiers of usage. We will always give ample notice before charging for a service and reward our early adopters with preferential pricing.
