What Is LlamaIndex?
LlamaIndex is a free, open-source Python and TypeScript framework for building retrieval-augmented generation (RAG) applications, with monetization coming from LlamaCloud, its separate paid managed platform for document parsing and extraction — used by over 90 Fortune 500 companies to power internal RAG applications. LlamaCloud runs a credit-based system where 1,000 credits cost $1.25, with parsing costs ranging $0.00125-$0.05625 per page depending on document complexity.
LlamaCloud offers four self-serve tiers: Free ($0, 10,000 credits/month, covering roughly 3,300 pages at the cost-effective tier or 10,000 pages at the fast tier), Starter ($50/month, 40,000 included credits, maintained parsing infrastructure, automatic updates, and support), Pro (flat $500/month for a comparable page/query volume), and custom Enterprise.
It's aimed at developers building RAG applications who want a free, open-source orchestration framework with an optional paid managed platform (LlamaCloud) for production-grade document parsing, with the credit-based LlamaCloud pricing meaning actual monthly cost depends on document volume and complexity rather than a flat subscription rate alone. See our Developer Tools directory for related tools like LangChain.
