Beep Link is a free and open-source Chrome extension for people who have trouble with vision. It is a simple way to make sure that links are highlighted when the mouse hovers over them. It was created to be used by people who have temporary or permanent vision problems.

The main functionality of the extension is the ability to customize the sound, color, and frequency of the sound that is emitted when the mouse is hovering over a link. It can be used on links that are inside an iframe or a non-a tag link.

The user has the ability to choose a default color and sound frequency from four different tones, or select a custom color and frequency from the options provided by the extension.
