ElementHistory is a free Chrome add-on developed by Matt Zeunert. It falls under the category of browsers and specifically belongs to the subcategory of add-ons and tools.

ElementHistory allows users to easily see what code created or updated a DOM element. By clicking on the ElementHistory icon, users can turn on the element history in a tab. If users want to track the entire history, they can simply reload the page.

This add-on is a useful tool for developers who want to keep track of changes made to DOM elements. With ElementHistory, developers can easily identify the code responsible for modifying specific elements on a webpage.
