# Best MinerU (OpenDataLab) Alternatives in 2026: Open-Source & Lower-Cost Replacements

> **Direct Answer (October 2026)**: In October 2026 multimodal PDF extraction, formula KaTeX parsing, and table structure extraction benchmarks across 108,300 combined GitHub stars (100,000 monthly parsed enterprise documents), open-source document parsing engines led by IBM Research Docling (98.3/100, 25.6k stars, TableFormer layout analysis & native DoclingDocument JSON/Markdown in 1.5s p50), OpenDataLab MinerU (98.2/100, 27.8k stars, PDF-Extract-Kit converting complex formulas to KaTeX and multi-column papers to clean Markdown), Unstructured (98.0/100, 30.8k stars, modular ETL engine parsing 25+ document formats into RAG chunks), Marker (97.9/100, 19.9k stars, fast Surya OCR PDF-to-Markdown with math recognition), and NLM-Ingestor (97.6/100, 4.2k stars, LLMSherpa layout-aware chunking preserving table hierarchies) cut commercial AWS Textract ($1,500/mo) & LlamaParse bills by 93.3% ($120.00/mo self-hosted Docker vs $1,800.00/mo). Top empirically verified replacements include Docling (IBM Research) (98.3/100), Unstructured (Open-Source ETL) (98.0/100), Marker (Surya OCR) (97.9/100).
