# LangGraph

Orchestrates long-running, stateful agents as graphs with durable execution and human-in-the-loop

Category: Agent frameworks. Pricing: Open source. License: MIT.

## Why you would want it

LangGraph is a low-level orchestration layer for agents and workflows that need to persist through failures and resume exactly where they left off. It provides short-term working memory and long-term memory across sessions, and lets a human inspect and modify agent state at any point during execution. It is built by LangChain Inc. but can be used without LangChain, and an equivalent JS/TS library, LangGraph.js, is available.

## Best for

- Long-running stateful agents
- Workflows with human review steps
- Teams already using LangChain or LangSmith

## Use it when

You want explicit control over an agent's control flow and state, with checkpoints it can resume from after a failure or a human review.

## Skip it if

You want a quick agent with planning, subagents and file system use out of the box; the README points to Deep Agents, a higher-level package built on LangGraph, for that.

## Install

Install with pip:

```sh
pip install -U langgraph
```
