LangGraph

LangGraph is an open source framework from LangChain for building AI agents that can handle long, complex tasks. You define your agent as a graph of steps, which gives you a lot of control over what happens and when.

What you can do with LangGraph

• Build agents with clear, controllable steps
• Keep memory and state across long running tasks
• Add human approval steps where you need them
• Build multi agent systems
• Deploy and watch your agents with LangSmith

Who it's for

LangGraph is for developers who need reliable agents in production, not just quick demos. You'll need to be comfortable with Python or JavaScript.

Pricing

LangGraph itself is free and open source. LangSmith, the platform for testing, monitoring, and deploying agents, has a free tier and paid plans.

Alternatives to LangGraph

Other agent frameworks include CrewAI and AutoGPT. Dify and Flowise offer visual builders.
