View long-term performance trends and sort pages to identify those with the most potential for optimization.
Since Google's page experience update, Core Web Vitals have been used as a search result ranking factor.
Tests your website with Google Lighthouse every day, so you don't have to wait 28 days for the field data to update.
PSI uses a network simulation to quickly serve up data. This is less accurate than testing in a real throttled environment, making it harder to use lab data to explain what you see in the field. DebugBear provides data you can rely on.
Pick test locations that match where your users are.
DebugBear runs on top of Lighthouse, but it collects a large amount of additional debug data to help you understand and optimize your site speed.
Share in-depth data on network and CPU activity, and compare different test results to understand a regression.
