LlamaIndex
RAG-first agent framework. Better defaults than LangChain for doc-corpora work; same local-runtime story.
Editorial verdict: “Best agent framework for RAG-first workloads. Less abstraction than LangChain.”

Which runtime + OS combos this app works against. Source of truth for "will it run on my setup?"
What it is
LlamaIndex (formerly GPT Index) is the RAG-first alternative to LangChain. Lower-abstraction APIs around chunking, embedding, retrieval. First-class support for local runtimes (Ollama, llama.cpp) and local embedders. Pick this when your primary task is RAG over a corpus.
✓ Strengths
- +Cleaner abstractions than LangChain for RAG
- +Strong evaluator tooling
- +Excellent docs
△ Caveats
- −Smaller ecosystem outside the RAG sweet-spot
- −Less obvious story for pure-agent workloads
