Website Speed Test with Dareboost Measuring Web Performance has never been so easy

Our test reports include not only all the necessary technical metrics for a full diagnosis of web quality, but also key indicators related to UX.

Through a video analysis of your web page loading, Dareboost computes 3 indices: Start Render, Visually Complete and Speed Index, which are widely considered to be the most relevant metrics when it comes to web performance as experienced by users.

To get an even more accurate view of your page loading, our reports feature a playback functionality that allows you to play back the loading video, as well as a filmstrip view to analyze each step of the page load.

Beyond the main web performance indicators, our reports also provide the necessary tools for web experts. Our Waterfall (Timeline) feature displays the loaded requests and HTTP responses and allows you to check the sent and received headers.

Our reports also feature the results of the Performance.Timing API in order to fully understand the loading process of your web page, with events regarding DOM loading (domInteractive, domContentLoaded, domComplete, etc.).

Dareboost has an extensive list of 13 test probes throughout the world so that you may test your website’s speed from various international areas: Hong Kong, London, Paris, Washington D.C., and many more… Check the complete list of our test probes to discover them all.
