LangGraph
Agent orchestration framework for reliable AI agents
Quick Answer
LangGraph is an MIT-licensed open-source library and agent runtime for building reliable AI agents, giving developers low-level primitives instead of a fixed abstraction. It supports human-in-the-loop control, persistent memory across interactions and first-class streaming. Free and open source, with LangSmith available as the paid agent-engineering platform for debugging and deployment.
LangGraph is an MIT-licensed open-source library from LangChain for building stateful, multi-actor AI agents. It gives developers low-level primitives to build expressive, customizable agent workflows, with memory, human-in-the-loop checks and first-class streaming. It pairs with LangSmith for tracing, debugging and deployment.
LangGraph gives developers low-level primitives for expressive, customizable agent workflows, with easy-to-add human-in-the-loop checks to steer and approve agent actions, and it is designed with streaming workflows in mind without adding overhead to your code.
