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

> **Direct Answer (October 2026)**: In October 2026 GraphRAG and agentic retrieval benchmarks across 252,904 combined GitHub stars (50,000 indexed enterprise documents), LightRAG (94.4/100, 40.1k stars) reduces GraphRAG entity-relation indexing token costs by 90.9% ($217.50 vs $2,400.00 in Microsoft GraphRAG Leiden community clustering) while achieving 92ms single-call query latency, whereas RAGFlow (94.9/100, 92.3k stars) leads deep PDF layout and hybrid BM25 + vector + graph recall (94.8%). Top empirically verified replacements include LightRAG (94.4/100), LlamaIndex (94.2/100), Haystack (93.4/100).
