Software projects change hands frequently. Oftentimes, developers are interested in the quality of the code before taking over responsibility on a project. This quality is commonly assessed using various code metrics, reducing the code into a handful of numbers. While useful, these numerical reductions quickly become detached from the real code. CodePanorama uses an alternative approach to summarize code not into numbers, but into images. By generating zoomed-out images of the code-base, the human eye can quickly spot anomalies without the need to rely on numerical metrics and statistics. This paper describes the tool CodePanorama, the images it generates, and the insights that can be gained from these images. We finally invite the software engineering community to start using it.

A video demonstration of the tool is available on the start page at https://codepanorama.io.
