LangGraph
Overview
A library for building stateful, multi-agent applications with LLMs, built on top of LangChain. Provides fine-grained control over agent loops.
LangGraph models agent applications as explicit graphs of nodes and edges, giving developers precise control over state, branching, and loops that higher-level frameworks abstract away. That control makes it well suited to production systems that need reliability, human-in-the-loop checkpoints, and durable state. It pairs with LangSmith for observability.
Key Features
- Explicit graph-based control of agent flow
- Durable state and checkpointing
- Human-in-the-loop interruption points
- Cycles and branching for complex logic
- Tight integration with LangChain and LangSmith
Best For
Engineers building production-grade, stateful agent systems that need fine-grained control.
Pros & Cons
Pros
- Precise control over complex agent logic
- Strong support for durable, resumable state
- Production-oriented with good observability
Cons
- Steeper learning curve than role-based frameworks
- More boilerplate for simple use cases
