LangGraph - Pros & Cons
Pros
- ✓Graph-based state machine gives precise control over execution flow with conditional branching, loops, and cycles

- ✓LangSmith integration provides production-grade tracing with visibility into every node execution and state transition
- ✓First-class streaming support with token-by-token, node-by-node, and custom event streaming modes
Cons
- ✗Steeper learning curve than role-based frameworks — requires understanding state machines, reducers, and graph theory concepts
- ✗Tight coupling to LangChain ecosystem means adopting LangChain's abstractions even if you only want the graph runtime
- ✗Graph definitions can become verbose for simple workflows that would be 10 lines in a linear framework
- ✗LangGraph Platform pricing adds significant cost for deployment infrastructure beyond the open-source core
