The Domain visualizer browser extension monitors and visualizes domains, which allows you to easily identify the origin of the site displaying in front of you. It is extremely useful for web developers, who often get confused if the website displaying in front of them is a local one or the test or production website of their client.

The HTML prepended into the body of the DOM can be configured in the add domain modal, where you can either configure the pre-selected configuration options or insert your own HTML.
