GitLab: Sharp avatars is a Chrome add-on developed by Tim Babych. It falls under the category of Browsers and the subcategory of Add-ons & Tools. This add-on aims to improve the look of project and user icons in GitLab for users of Retina monitors.

The add-on works by finding avatar images in GitLab pages and providing the browser with a higher-resolution version of them, if it exists. Currently, GitLab scales down high-resolution icons to 48px, but this extension attempts to request a less downscaled version of the icon.

This add-on addresses a common issue faced by GitLab users who upload high-resolution icons, only to have them scaled down. By providing a higher-resolution version of the icons, GitLab: Sharp avatars enhances the visual experience for users with Retina monitors.
