Overview
QuPath (Quantitative Pathology & Bioimage Analysis) is an open-source software platform for digital pathology analysis developed at the University of Edinburgh (and previously Queen's University Belfast). It provides a comprehensive environment for viewing, annotating, and analyzing whole slide images (WSIs) from digital pathology scanners, supporting common tasks including cell detection, tissue classification, biomarker quantification (IHC, IF), and tumor microenvironment characterization. Pathologists, biomarker researchers, and computational pathology teams use QuPath for quantitative analysis of histology slides in research and translational settings. The software supports a wide range of WSI formats (SVS, NDPI, CZI, TIFF pyramids), integrates with deep learning models including StarDist for cell detection, and provides a scripting interface (Groovy) for batch processing and automated analysis pipelines. Over 5,000 papers cite QuPath, and it is taught in digital pathology courses worldwide. QuPath's differentiators are its combination of usability and extensibility — pathologists without programming experience can train pixel classifiers and run cell detection interactively, while computational scientists can extend functionality via a Java/Groovy scripting API and an active extension ecosystem. Unlike commercial pathology AI platforms, QuPath is completely free and open-source, with an active GitHub community of over 1,000 contributors maintaining extensions and integrations with Python deep learning libraries.
