The short version

What is Orange Data Mining?

Orange is a free, open source desktop app for machine learning and data visualization, made by the Bioinformatics Lab at the University of Ljubljana. You build an analysis by connecting widgets on a canvas, with no code needed.

Orange was first released in 1996 and is written in Python, Cython, C++ and C. The current version is 3.40.0, released in December 2025. Add-ons cover text mining, network analysis, time series, spectra and gene expression data. People often search for an online version, but the official site only offers downloads for Windows, macOS and installs through pip or conda. There is no browser version.

Bottom line: Orange is a strong pick for teaching, learning and quick exploratory analysis at no cost. If you need to work in a browser or share live analyses with a team, look at hosted tools.
