Langraph

LangGraph is the low-level, open-source orchestration framework from LangChain: it builds, manages, and deploys complex, stateful AI agent workflows using a graph-based architecture.

LangGraph, an open-source framework from the LangChain team, delivers the robust, low-level orchestration required for production-ready AI agents. It leverages a graph-based architecture (nodes and edges) to model and manage intricate, stateful workflows, ensuring reliable, multi-step reasoning. This design supports critical features: durable execution, comprehensive memory, and human-in-the-loop oversight. Companies like Klarna, Replit, and Elastic rely on LangGraph to deploy sophisticated agent systems, such as multi-agent chatbots or complex decision-making engines, with complete control over the cognitive architecture.
