Lighthouse lab reports

Complement field data with lab data

Tests your website with Google Lighthouse every day, so you don't have to wait 28 days for the field data to update.

Like PageSpeed Insights, but more accurate

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.

Run tests from 20+ global locations

Pick test locations that match where your users are.

Real user monitoring

Collect data across your whole website

Install a analytics snippet and see what pages on your website are slow. Then use our detailed page experience data to optimize them.

Improve Interaction to Next Paint

Google's new Core Web Vitals metric is hard to debug in the lab. DebugBear tells you what page elements are causing long interaction delays.

Analyze performance with in-depth data

Beyond metrics and Lighthouse audits

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.

Give developers the details they need

Share in-depth data on network and CPU activity, and compare different test results to understand a regression.

Why Core Web Vitals are important

Better user experience

Make your website a joy to browser by ensuring content loads quickly and pages respond quickly to user interactions.

Improved SEO

Google uses the Core Web Vitals as a search result ranking factor.

Higher conversion rates

Get more visitors to buy your products by making your website engaging, reducing bounce rates, and making purchases easy.

Interaction to Next Paint correlated to user actions

Fix Interaction to Next Paint

See what page interactions are slow

Get a breakdown of what page elements users are interacting with and where content is unresponsive are slow.

Identify slow scripts

DebugBear uses the Long Animation Frames API to identify slow scripts that are delaying user interactions.

INP component breakdown

See if slow interactions are caused by background tasks, event processing, or presentation delays.

Reduce Largest Contentful Paint

Custom recommendations

Find out what you can do to improve your LCP score and quickly try out optimizations with our experiments feature.

See how LCP varies between users

How long your page takes to load depends on the users device and how they've interacted with the page before. DebugBear provides a breakdown of all the page elements that are responsible for the LCP for different people.

Break down the LCP metric

Is poor LCP caused by slow server response times, render-blocking stylesheets, or slow image loading? DebugBear breaks down the LCP metric to help you focus your work where you can have the biggest impact.

Optimize Cumulative Layout Shift

Identify CLS issues

Track layout shift across your entire website and see which pages are impacted by poor CLS scores.

See what content is actually shifting

CLS can't always be replicated with synthetic tests. But real user data can tell you what content is moving around unexpectedly.

Review individual page visits

Check out details about a specific page view, how the user interacted with the page, and how that resulted in layout shift.
