// Our Verdict
LlamaIndex is the right choice when document ingestion, OCR, or knowledge retrieval is the core of your agent's work. It leads the field on RAG tooling and LlamaParse makes complex document processing genuinely easier.
Best for: Agents whose primary job is retrieval, document processing, knowledge base operations, or multi-modal parsing
// Strengths
LlamaParse: best-in-class document parsing and OCR for complex formats
Event-driven Workflows abstraction for multi-step async agent logic
48.4k GitHub stars and 23.9k dependents — strong adoption
Both Python and TypeScript support with LlamaCloud managed option
492+ releases with a long track record of production use
// Weaknesses
Heavier than needed when retrieval is not the primary job
LlamaCloud costs can surprise teams at production scale
Agent orchestration is secondary to retrieval — not the right choice for pure orchestration work
