Alternative to Google PageSpeed Insights

See how your website loads

Review the loading process of your website step by step with a filmstrip view, or play a video recording of how a user would have experienced it.

Detailed Request Waterfall

DebugBear provides a detailed report on what resources your website loads and what's holding back rendering.

Custom Performance Recommendations

Lighthouse-based tools like PageSpeed Insights provide a lot of performance recommendations, but they're not always actionable. Our tool surfaces opportunities for improvement and explains how you can apply them to your website.

Performance testing in a controlled lab environment

We set up a controlled lab environment with fixed network and CPU speeds. Then we load your website and load detailed debug data to help you optimize it.

Metrics from real users

In addition to providing lab data we also use Google's CrUX API to show you how real Chrome users experience your website. This is the data that Google uses as a search engine ranking signal.

PageSpeed Insights uses simulated throttling

That means the page is loaded on a fast network and on a fast device. Then Google estimates how fast your website would have loaded on a slower connection. However, this estimate is often inaccurate.

DebugBear collects data on a throttled connection

That means our performance data is more reliable and we can offer you more in-depth reporting to help you speed up your website.

Run daily page speed tests

DebugBear lets you schedule tests to run automatically. That way you'll get alerted to changes and can compare test results to see what website update impacted performance.

Real user monitoring

In addition to running scheduled lab tests, DebugBear also lets you collect real user performance data across your whole website.

Identify slow pages, segment visitors, and see what optimizations would have the biggest impact.

Get started in minutes

Simply enter your website URL to start monitoring. No code changes needed, no complex configuration required.

Test from multiple locations

Unlike PageSpeed Insights which tests from a single location, DebugBear lets you test from 30+ global locations to match where your users are.

Advanced configuration when you need it

Test authenticated pages, dismiss cookie banners, block ads, or inject custom scripts. DebugBear adapts to your testing needs.
