help DebugBear FAQ

Does the DebugBear extension measure Core Web Vitals like LCP and CLS?

Yes, DebugBear simulates real user experiences to calculate crucial Google Core Web Vitals, including Largest Contentful Paint (LCP) and Cumulative Layout Shift (CLS). This helps developers ensure their website meets modern search engine performance standards.

Can DebugBear analyze the execution time of third-party JavaScript tags?

One of DebugBear's most powerful features is its ability to isolate and track the performance impact of third-party scripts. It shows developers exactly how much time external tags, like Google Analytics, add to the total page load.

Does the DebugBear extension use Google's Lighthouse engine?

DebugBear utilizes the underlying open-source Lighthouse engine to provide detailed performance audits. However, it wraps the data in a much more user-friendly interface and adds continuous monitoring capabilities not found in the standard DevTools.

Is the DebugBear browser extension completely free to use?

DebugBear offers a highly capable free Chrome extension that provides instant, detailed performance audits for individual pages. The company also offers premium SaaS tiers aimed at enterprise users who need automated, continuous website monitoring.
