Domain Lens is a free Chrome add-on designed to provide instant insights about any website directly from the browser toolbar. Users can easily view essential information including the domain name, resolved IP addresses (both IPv4 and IPv6), and server location, which is displayed with a country and city flag. This tool simplifies the process of gathering domain data, making it accessible with just a click.

In addition to basic domain information, Domain Lens offers a global ranking system that categorizes websites into levels such as Outstanding, Excellent, and Very Good, allowing users to quickly assess a site's standing. A tooltip feature also provides details on domain age, giving insights into how long a website has been operational. This add-on is particularly beneficial for web developers, marketers, and cybersecurity enthusiasts seeking reliable domain data without navigating away from their browsing experience.
