Pros & cons
LangGraph
Pros
- Explicit control over agent state and branching
- First-class human-in-the-loop and checkpointing
- Strong fit for durable, long-running workflows
- Large ecosystem and active development
Cons
- Requires real engineering investment
- Lower-level than no-code agent builders
- You own deployment and observability
LlamaIndex
Pros
- Deep, well-documented retrieval toolkit
- Handles complex and messy document types
- Managed LlamaCloud option for scale
- Large ecosystem of connectors
Cons
- Retrieval quality still depends on your tuning and evals
- Overlapping features with LangChain can confuse
- Fast-moving API surface
Which should you choose?
LangGraph is built around engineering teams building multi-step agents; LlamaIndex leans more toward teams building rag over internal data. Shortlist the one whose strengths line up with your biggest constraint.
