LangChain vs LlamaIndex vs Haystack: What Two Weeks in Production Actually Taught Me

My team got handed a RAG project earlier this year — 40,000 documents, mix of PDFs and Confluence exports, users who would notice if answers were wrong. I'd used LangChain for smaller stuff before, but this was the first time I actually ran all three...
