LangGraph
Freemium · $39/moLow-level framework for building stateful, controllable agents
What is LangGraph?
LangGraph is an open-source framework from LangChain for building agents as graphs of steps with explicit state. Developers choose it when they need control over loops, branching and human approval in agent workflows.
Each node in the graph is a function or model call, and edges decide what runs next. Built-in persistence lets agents pause for human input, resume later and keep memory across sessions. LangGraph runs in Python and JavaScript, and LangSmith adds hosted deployment, tracing and evaluation for production agents.
