# Best LlamaIndex Alternatives in 2026: Open-Source & Lower-Cost Replacements

> **Direct Answer (October 2026)**: Engineering teams evaluate LlamaIndex alternatives in 2026 to deploy turnkey DeepDoc visual PDF layout + hybrid BM25/GraphRAG engines (RAGFlow), cut entity-relation graph indexing tokens by 90.9% (LightRAG), or use explicit YAML pipeline DAGs (Haystack). Top empirically verified replacements include RAGFlow (94.9/100), LightRAG (94.4/100), Haystack (93.4/100).
