# App development in LangSmith Deployment

**LangSmith Deployment** builds on the open-source [LangGraph](/oss/python/langgraph/overview) framework for developing stateful, multi-agent applications.
LangGraph provides the core abstractions and execution model, while LangSmith adds managed infrastructure, observability, deployment options, assistants, and concurrency controls—supporting the full lifecycle from development to production.

<Callout icon="packages" color="#4F46E5" iconType="regular">
  LangSmith Deployment is framework-agnostic: you can deploy agents built with LangGraph or [other frameworks](/langsmith/deploy-other-frameworks). To get started with LangGraph itself, refer to the [LangGraph quickstart](/oss/python/langgraph/quickstart).
