UX Focus for Waterfalls and Third Parties
At SpeedCurve, we want to help designers and developers have better insight into the user experience they're delivering. For websites, this means understanding when the critical parts of the page render and what might be blocking rendering.
We've redesigned our waterfall chart to really highlight the relationship between the assets on the page and their affect on the user experience. Now as you move you mouse over the waterfall chart we show you exactly what a user is seeing at that millsecond while the page loads. This makes it much easier to identify any Javascript or CSS that might be blocking the page from rendering. I recently used this new combined waterfall and filmstrip view to identify a common issue with hero images being delayed.
