Hosting Detector is a free Chrome add-on designed to help users discover the hosting providers of the websites they visit. It addresses the complexities of the hosting market, where many companies do not manage their own servers. This tool provides insights into the hosting arrangements, revealing whether a company is leasing server space from another provider.

The application is particularly useful for web developers and site owners who want to understand the infrastructure behind their websites. By using Hosting Detector, users can gain clarity on whether their hosting company is the actual server manager or merely a reseller. This can assist in making informed decisions regarding web hosting services and enhance the overall web management experience.
