Frequently asked questions
When should I use LangGraph over LangChain?+
The moment you need cycles, retries, memory across sessions, or coordinated multi-agent behaviour — LangGraph is built for those patterns; LangChain alone is not.
Is LangGraph production-ready?+
Yes. It powers agent products at LinkedIn, Klarna, Uber, Elastic and hundreds of startups. LangGraph Platform adds hosted deployment.
