Cookies Landing Page
The first component in PSAT's Privacy Sandbox DevTools panel corresponds to the area of Cookie Analysis.
As discussed in the Evaluation Environment section, PSAT can be configured to avoid using too many resources by restricting the tool to only analyze a single tab at a time. If that configuration option is set, PSAT presents an Analyze this tab button to switch the focus of the tool to the current tab.
Once the PSAT's focus has been switched to the current tab, we get to the Cookies Landing Page:
The purpose of PSAT's cookie landing page is to provide information and insights regarding the behavior and distribution of cookies on web pages, while navigating across sites during browsing sessions.
Currently the cookie landing page provides a classification of observed cookies on a given page (total, first-party, third-party).
PSAT leverages and contributes to the Open Cookie Database, which is an open-source effort to describe and categorize cookies in the ecosystem. Using that DB, PSAT's provides a classification for some of the observed cookies, into the categories: Functional, Marketing, Analytics, and Uncategorized.
As PSAT continues to evolve rapidly, the cookie landing page will incorporate more information and insights about cookie usage and behaviors.
PSAT helps developers ensure a smooth transition through the deprecation of 3P cookies by identifying known breakages caused by deprecated libraries. Information about these breakages is available on the cookie landing page, with an expansion toggle, details of broken features, and possible migration guides.

The PSAT extension has the capability to adopt more such libraries, which could help identify more libraries that might cause issues in the future.
