About this subject

This page tracks the presence and types of custom 404 images used in GitHub repositories. A custom 404 page can inject personality into a project and signal a higher level of polish and attention to detail, indicating a potentially more engaged community.

The data is gathered by analysing publicly available GitHub repositories. We identify repositories that have configured a custom 404 image and categorise them by image type (e.g., static image, GIF, animated GIF).

While not a direct measure of code quality, the adoption of custom 404 images can be a subtle indicator of a repository's care and creative flair. It's a small but interesting metric that can highlight repositories that go the extra mile.
