LangGraph

The product is an open-source agent runtime and low-level orchestration framework for building agents that reliably handle complex tasks. It provides primitives for state, memory, streaming, and human-in-the-loop controls to guide and moderate agent behavior. It is for software developers and engineering teams in businesses building production AI agents. It is positioned as a more expressive, low-level alternative to generic agent frameworks for bespoke, complex workflows, delivered as an open-source framework with production runtime.
