> LangGraph is an MIT-licensed, graph-based agent runtime from the LangChain team; unlike most orchestration frameworks it treats durable execution and human-in-the-loop as first-class primitives rather than add-ons.

Graph-based agent runtime by the LangChain team with native durable execution and human-in-the-loop.
