LangGraph
Library for building stateful multi-agent applications with LLMs.
About
LangGraph by LangChain is a low-level orchestration framework for building stateful, long-running agents and multi-actor workflows. It models applications as graphs with cycles, persistence, and human-in-the-loop checkpoints, giving explicit control over how agents loop and hold state. It can be used standalone or alongside the wider LangChain ecosystem and has a parallel JavaScript library. Used in production by companies such as Replit and Elastic. Released under the MIT license.
