Cognee - Pros & Cons
Pros
- ✓Knowledge graphs capture entity relationships that vector-only RAG systems miss, improving multi-hop reasoning and complex question answering
- ✓Open-source core with no vendor lock-in allows full control over knowledge graphs stored in standard Neo4j databases
- ✓Hybrid retrieval combines graph traversal with vector similarity search for comprehensive information discovery
- ✓28+ data source integrations with unified processing handles diverse input formats from PDFs to conversations
- ✓Pipeline-based architecture allows customization of entity extraction, relationship mapping, and storage backends
- ✓Automatic knowledge graph construction reduces manual knowledge engineering compared to building graphs from scratch
Cons
- ✗Knowledge graph quality depends heavily on input data quality and extraction model accuracy, requiring careful tuning for specialized domains
- ✗Neo4j infrastructure adds operational complexity compared to vector-only solutions that just need embedding storage
- ✗Graph construction and queries are slower than simple vector retrieval, particularly for large document collections
LlamaIndex - Pros & Cons
Pros
- ✓Best-in-class retrieval strategies: hybrid, parent-child, summary indexes, knowledge graphs
- ✓LlamaParse is the strongest PDF/document parser for enterprise RAG today
- ✓Open-source library is MIT-licensed and runs anywhere
- ✓Workflows agent layer is a clean alternative to LangGraph for stateful task graphs
- ✓10,000 free LlamaCloud credits make evaluation painless
Cons
- ✗LlamaCloud paid pricing is credit-based and harder to model than seat pricing
- ✗Workflows ecosystem is younger than LangGraph's; fewer multi-agent examples in the wild
- ✗Library API has churned over major releases — older tutorials are often out of date
- ✗Visual builder UX is not part of the product; teams that want no-code go elsewhere
- ✗Pure agent orchestration with complex branching is still cleaner in LangGraph
