Track user-centric performance metrics like Largest Contentful Paint and Cumulative Layout Shift.
Lighthouse is the tool that powers Google's PageSpeed Insights service. Track scores for performance, accessibility, and SEO.
Compare trends across different websites, and optimize your site performance.
Google is now using web vitals as a ranking factor. Optimizing site experience is an important part of technical SEO.
In addition to the lab-based Lighthouse tests, DebugBear also tracks the data Google collects from real Chrome users.
Your page load times just went up, but why? DebugBear shows an in-depth comparison between any two test results, so you can see what changed.
Use detailed debug data on rendering, CPU tasks, and network requests to identify what's slowing down your site.
Just enter the URLs of the pages you want to monitor and we'll do the rest.
Invite as many users as you need, or give everyone access with a shareable URL.
Access pages behind authentication, set up performance budgets, or hide popups with a custom script.
Run tests with the API or configure monitored pages.
Catch regressions early by testing each pull request with DebugBear. Report results on GitHub or your CI system.
Download metrics as CSV or JSON. Export data with the API or receive every test result through webhooks.
Significant changes are detected automatically, without the need to set up thresholds. But if you need to you can fully customize the alerts.
Send alerts by email, in Slack, or in Microsoft Teams.
