Docling vs Unstructured

Both are alternatives to AWS Textract. Here's how they stack up — verified facts, no spin.

Also searched as Unstructured vs Docling — same comparison, one verdict.

94

Docling

TOP PICK

IBM's document converter. Layout-aware PDF to clean Markdown, MIT.

OPEN SOURCEMITSELF-HOSTLOCAL-FIRST

Docling parses PDFs, Office documents, images and HTML into a structured representation that preserves reading order, tables, figures and headings, then exports to Markdown or JSON. It uses purpose-trained layout and table models rather than heuristics, which is why it holds up on multi-column academic papers and financial statements where simpler extractors interleave columns into nonsense. It integrates directly with LlamaIndex and Haystack, is MIT licensed, and runs entirely locally including on CPU.

90

Unstructured

One interface for every document format you will actually be handed.

OPEN SOURCEApache-2.0SELF-HOSTLOCAL-FIRST

Unstructured normalises an unusually wide range of inputs — PDF, Word, PowerPoint, Excel, HTML, email, EPUB, images — into a consistent element structure of titles, narrative text, tables and lists, ready for chunking. Breadth is the point: real corpora are never one format, and writing a parser per type is where ingestion projects stall. The open library is Apache-2.0 and runs locally; the company also sells a hosted API with additional models.

The verdict

Docling is Macrostack's recommended AWS Textract alternative, so it's our pick here.

Docling

Strengths

  • +Layout-aware — preserves reading order, tables and structure
  • +Outputs clean Markdown/JSON that drops into a RAG pipeline
  • +Direct integrations with LlamaIndex and Haystack
  • +MIT, fully local, no per-page cost

Trade-offs

  • Slower per page than cloud OCR on very large batches
  • Handwriting support is weak compared with Textract
  • No specialised invoice or receipt models

Unstructured

Strengths

  • +Widest input-format coverage of anything here
  • +Consistent element output regardless of source format
  • +Chunking strategies built in for RAG pipelines
  • +Apache-2.0 open library

Trade-offs

  • Best-quality models sit in the paid hosted tier
  • Local install pulls in heavy system dependencies
  • Depth on complex PDFs is below Docling's
