Better data quality than Lighthouse

Real network throttling

Lighthouse and PageSpeed Insights use simulated throttling to test your website. The data is actually always collected on a fast connection!

DebugBear actually slows down the network instead of relying on a simulation that's often inaccurate.

Avoid random outliers and false alerts

DebugBear always repeats tests before sending an alert, so you don't have to deal with issues you can't replicate.

Network request waterfall

Detailed technical reports

Over 70 different metrics

We track everything from Web Vitals to Lighthouse scores and page weight. We also provide debug data for each metric to help you improve it.

Easily filter data to focus on what you need

Want to optimize the Largest Contentful Paint? No problem! We'll show you the responsible DOM element and what network requests you need to speed up.

Industry-leading request waterfall

What requests are render-blocking? Are any resources preloaded? Does the LCP image use the fetchpriority attribute? How is bandwidth allocated across requests?

Our waterfall chart shows all of this information and puts it into context.
