Reviewer scorecard
“Best framework for RAG specifically. The data connectors and query engines are production-grade. Less bloated than LangChain.”
“If you're in the .NET ecosystem, this is the best AI integration SDK. Plugin architecture is clean and extensible.”
“Focused scope makes it more maintainable than LangChain. LlamaCloud managed parsing is genuinely useful.”
“Microsoft vendor lock-in disguised as open source. Everything points you toward Azure. Use provider-agnostic alternatives.”
“Data integration is the real bottleneck for enterprise AI. LlamaIndex is correctly positioned at this chokepoint.”
“Enterprise AI adoption will go through existing stacks. Semantic Kernel meets .NET developers where they are.”
