uBO-Scope is a free Chrome add-on developed by Raymond Hill (gorhill) that allows you to measure your 3rd-party exposure score for the websites you visit. With this tool, you can gain insights into your own third-party exposure and understand the impact it has on your privacy.

Privacy exposure is a crucial aspect of online security, and uBO-Scope helps you monitor and evaluate your 3rd-party exposure. It defines a third-party as a network request to a remote server with a different base domain name than the URL in the address bar. The add-on calculates a 3rd-party exposure score based on the number of distinct third parties on a web page and their level of ubiquity.
