What Is Docling? Docling 是什么？
Docling is an open-source project with 62k+ GitHub stars. IBM's document parsing and understanding library
The project focuses on document, parsing, ocr use cases and is designed as a developer library or framework—you integrate it into your own application by importing it as a dependency.
Source code is available at github.com/DS4SD/docling. With 62k+ GitHub stars, it ranks among the most battle-tested open-source tools in this space—meaning most common use cases are well-documented with community solutions available.
A well-regarded project with 12k+ stars, Docling has proven itself in production deployments. Worth trying if you need this capability without cloud API costs or data privacy concerns. The self-hosted version requires more setup than the managed alternative, but gives you full control over the deployment.
