Highlighted rows are where these differ.
Graphiti
- Records when something was true and when it was learned
- The engine behind Zep's LongMemEval result
Best for facts that change over time.
LangChain & LangGraph
- LangGraph adds durable state and checkpointing
- Widely used, and widely argued about
Best for agents that retrieve as one step among many.
RAGFlow
- Strong document parsing built in
- The usual entry point for non-developers
Best for teams without a Python engineer.
