LangGraph
LangChain's stateful multi-agent framework for building controllable, cyclical AI workflows and production agent systems.
What it does
LangGraph is a Python and JavaScript framework for building stateful, multi-actor AI applications - providing the graph-based orchestration infrastructure for complex AI agent workflows that require loops, conditionals, and persistent state across steps. LangGraph is part of the LangChain ecosystem and designed for building production-grade agentic systems. AI capabilities include stateful graph execution that maintains memory and context across multi-step agent workflows, controllable agent loops that support human-in-the-loop checkpoints and interruptions, multi-agent coordination enabling specialized agents to collaborate on complex tasks, streaming execution that returns intermediate steps to users in real time, built-in persistence for long-running agent workflows that can pause and resume, and LangGraph Platform for deploying agent systems as production APIs with monitoring via LangSmith.
Why AI-NATIVE
LangGraph is AI-native - a stateful agent orchestration framework for building autonomous multi-step AI workflows is an inherently AI-native infrastructure product.
Best for
Individual AI developers use LangGraph for building personal agent workflows - open-source framework with no cost for experimentation.
Small AI teams use LangGraph for building production agent applications - controllable execution and human-in-the-loop checkpoints enabling safe production deployment.
Mid-market engineering teams use LangGraph for complex AI workflow automation - multi-agent coordination handling enterprise business processes that require branching, loops, and state.
Large enterprises use LangGraph Platform for production agent deployment - managed infrastructure and LangSmith observability enabling enterprise-grade agentic applications.
Limitations
LangGraph is a developer framework — non-technical users cannot deploy agents without coding knowledge or a developer partner.
CrewAI and Microsoft AutoGen offer competing multi-agent frameworks — developers should compare API design, community size, and production tooling.
LangGraph's node-and-edge graph architecture is powerful but requires developers to think differently about workflow design — teams accustomed to linear pipelines need adjustment time.
Alternatives by segment
LangGraph open-source free. LangGraph Platform (managed) pricing not published. LangSmith observability starts free. Annual contracts for enterprise.
