LangGraph Cloud is now in Beta
Deploy LangGraph agents at scale with LangGraph Cloud (available for Python). Get 1-click deployment, scalable servers and task queues, and integrated monitoring to streamline custom workflows.
Balance agent control with agency
Gain precision and control with LangGraph to build agents that reliably handle complex tasks.
Controllable cognitive architecure for any task
LangGraph's flexible API supports diverse control flows – single agent, multi-agent, hierarchical, sequential – and robustly handles realistic, complex scenarios.
Ensure reliability with easy-to-add moderation and quality loops that prevent agents from veering off course.
See the docs
Designed for human-agent collaboration
With built-in statefulness, LangGraph agents seamlessly collaborate with humans by writing drafts for review and awaiting approval before acting. Easily inspect the agent’s actions and "time-travel" to take a different action at a specific time.

Trusted by companies taking agency in AI innovation:
LangGraph helps teams of all sizes, across all industries, from ambitious startups to established enterprises.
“LangChain is streets ahead with what they've put forward with LangGraph. LangGraph sets the foundation for how we can build and scale AI workloads — from conversational agents, complex task automation, to custom LLM-backed experiences that 'just work'. The next chapter in building complex production-ready features with LLMs is agentic, and with LangGraph and LangSmith, LangChain delivers an out-of-the-box solution to iterate quickly, debug immediately, and scale effortlessly.”
“LangGraph has been instrumental for our AI development. Its robust framework for building stateful, multi-actor applications with LLMs has transformed how we evaluate and optimize the performance of our AI guest-facing solutions. LangGraph enables granular control over the agent's thought process, which has empowered us to make data-driven and deliberate decisions to meet the diverse needs of our guests.”
“It's easy to build the prototype of a coding agent, but deceptively hard to improve its reliability. Replit wants to give a coding agent to millions of users — reliability is our top priority, and will remain so for a long time. LangGraph is giving us the control and ergonomics we need to build and ship powerful coding agents.”

LangGraph FAQs
Do I need to use LangChain to use LangGraph? What’s the difference?
No. LangGraph is an orchestration framework for complex agentic systems and is more low-level and controllable than LangChain agents. On the other hand, LangChain provides a standard interface to interact with models and other components, useful for straight-forward chains and retrieval flows.
How is LangGraph different from other agent frameworks?
Other agentic frameworks can work for simple, generic tasks but fall short for complex tasks bespoke to a company’s needs. LangGraph provides a more expressive framework to handle companies’ unique tasks without restricting users to a single black-box cognitive architecture.
Does LangGraph impact the performance of my app?
LangGraph will not add any overhead to your code and is specifically designed with streaming workflows in mind.
Is LangGraph open source? Is it free?
Yes. LangGraph is an MIT-licensed open-source library and is free to use.
Is LangGraph Cloud open source?
No. LangGraph Cloud is proprietary software that will eventually be a paid service for certain tiers of usage. We will always give ample notice before charging for a service and reward our early adopters with preferential pricing.
How do I enable LangGraph Cloud?
For now, LangGraph Cloud is in closed beta. You can join this waitlist to try it out for free, and we’ll notify you with deployment instructions once you’re off the waitlist. Check out the docs.
How are LangGraph and LangGraph Cloud different?
LangGraph is a stateful, orchestration framework that brings added control to agent workflows. LangGraph Cloud is a service for deploying and scaling LangGraph applications, with a built-in Studio for prototyping, debugging, and sharing LangGraph applications.
