May 2023 Release Notes

Improved performance budgets

You can now define performance budgets for all available metrics. You'll see these budgets in the page dashboard and get alerts when a budget is breached.

In addition to that, budgets now support bulk editing.

Improve webhooks

Webhooks allow you to get notified of any test results on DebugBear.

Now you can filter webhook messages to only get notifications for specific pages or tests. Webhook messages also include information about breached performance budgets.

Interpret real-user LCP more easily

When the CrUX LCP metric is selected we now dispaly a breakdown that explains whether a high metric value is caused by server response time, render-blocking content, or by something else.

New articles

• Improve Page Speed With Async And Defer – the async and defer attributes are important tools to ensure requests don't block rendering
• Cumulative Layout Shift Differences In Lab And Field Data – real user metrics often don't match lab-based results and this article takes an in-depth look at why that happens for the CLS metric
• Measure And Optimize Speed Index – learn how Speed Index is measured and how it's different from the Largest Contentful Paint
