Docling Studio — open-source visual inspection tool for Docling pipelines

Hey everyone

I built Docling Studio , an open-source visual inspection layer for Docling.

The problem: if you’ve used Docling, you know the extraction engine is powerful — but validating outputs means digging through JSON and mentally mapping bounding box coordinates back to the original pages. No visual feedback loop.

What Docling Studio does:

• Upload a PDF, configure your pipeline (OCR engine, table extraction, enrichment)

• Run the conversion

• Visually inspect every detected element — bounding boxes overlaid on original pages, element types, content preview on click

• Two modes: local (embedded Docling) or remote (Docling Serve)

Stack: Vue 3 / TypeScript + FastAPI / Python, fully Dockerized (multi-arch), 180+ tests.

Why it matters for RAG workflows: without seeing what Docling extracts, it’s hard to evaluate chunk quality before feeding your pipeline. Docling Studio gives you that feedback loop.

The project is part of the Docling ecosystem (Linux Foundation AI & Data). Feedback, issues, and contributions welcome — especially interested in hearing what features would help your document AI workflows.
