Comparer	Compare visual differences between similar content with a sliding panel.	imagery niche	comparer

This is especially useful for comparing images, but can be used for comparing any type of content (for an example of using it to compare entire UIs, check out our theme pages). For best results, use content that shares the same dimensions. The slider can be controlled by dragging or pressing the left and right arrow keys. (Tip: press shift + arrows to move the slider in larger intervals, or home + end to jump to the beginning or end.)
