Our take
Pick LlamaIndex if builders wiring RAG or document extraction who will use the MIT library and/or LlamaParse credits. Pick Zep if teams shipping agents that must remember users across sessions and will stay inside a monthly credit pool. Skip LlamaIndex if people who only want a visual agent canvas (Langflow) or traces (Langfuse).
