Reviewer scorecard
“Best framework for RAG specifically. The data connectors and query engines are production-grade. Less bloated than LangChain.”
“Solves a real problem — AI memory across sessions. Simple API and works with any LLM provider.”
“Focused scope makes it more maintainable than LangChain. LlamaCloud managed parsing is genuinely useful.”
“Early-stage with limited production deployments. Building your own memory layer with a vector DB isn't that hard.”
“Data integration is the real bottleneck for enterprise AI. LlamaIndex is correctly positioned at this chokepoint.”
“Persistent AI memory is a missing piece for meaningful AI assistants. Mem0 is the leading solution in this space.”
