About
LangGraph is a library by LangChain for building stateful, multi-step LLM applications as graphs. It adds cycles, controllability, and persistence to LangChain. Ideal for building complex agent architectures with explicit state management and human-in-the-loop patterns.
Strengths
- Explicit state management
- Graph-based control flow
- Great for complex agents
Limitations
- Requires LangChain knowledge
- Steep learning curve
- New and evolving API
