DebugBear now makes it easier to show historical metrics data for all monitored pages.

Trendlines​

The project overview page now shows weekly averages for the last 10 weeks, rather than just the most recent scores and metrics.

Lighthouse 7.0​

DebugBear now runs test using the latest version of Lighthouse.

  • The third-party facades audit suggests using a static placeholder for third-party widgets, until the user starts interacting with the widget.
  • In some cases Lighthouse now waits longer for the page to load, for example if there's a single XHR request that delays rendering. This makes the metrics more accurate.

Improved mobile site​

The mobile project overview now also shows performance metrics, and you can use the same filters as on desktop.
