Our take
Pick LlamaIndex if builders wiring RAG or document extraction who will use the MIT library and/or LlamaParse credits. Pick Mem0 if agent builders who want a managed memory store and will stay inside the monthly add/retrieve caps. Skip LlamaIndex if people who only want a visual agent canvas (Langflow) or traces (Langfuse).
