Video Replay, Filmstrip and UX analysis

Not only our test reports provide all the needed technical metrics for a full diagnosis about web quality, but also major indicators dealing with User Experience (UX).

Thanks to the video analysis of your web page loading, Dareboost computes Start Render, Visually Complete and Speed Index, widely renowned as the most relevant metric for the web performance as experienced by users.

Furthermore, in order to get the most accurate view of each displaying steps of your web page, all of our reports allow you to replay its loading video and access to its detailed filmstrip.

Hightlight on your web performance : Waterfall, Timeline

Beyond the major web performance indicators, our reports also provide all the necessary tools to any web experts. Our waterfall (Timeline) will show you all the loaded requests and HTTP responses. And you'll be able to consult all the sent & received headers.

The results of the Performance.Timing API are also displayed in order to deeply understand how your web page had been loaded, thanks to events regarding DOM loading ( domInteractive, domContentLoaded, domComplete, etc)
