LangGraph
LangGraph is the open-source agent orchestration framework from the LangChain team. It models multi-step tasks as traceable state graphs, helping readers decide when long-running, human-in-the-loop agent workflows justify the investment.
Maintained by the LangChain team, LangGraph is a low-level orchestration framework for multi-step agents: tasks split into nodes, intermediate results live in shared state, so long workflows can pause, replay, and take human input. Its official repository sits under the langchain-ai organization on GitHub and is MIT licensed. It adds state-machine scheduling for agent projects needing resumable runs and branching decisions.
