As mobile and tablet use increases, it’s important that you understand how your site performs across a wide range of target platforms. SpeedCurve’s Responsive Design dashboard provides the answers, not just in numbers, but with video and filmstrips that show rendering performance as well.
We load each URL in a variety of viewport sizes, orientations, and connection speeds. The results let you see what your site looks like on different form factors, how quickly it renders, and whether your content is optimized for different users on different devices. Visualising the impact of design and content choices for your website enables better collaboration between designers and developers.VIEW DEMO
SpeedCurve allows you to track your own performance as well as the performance of your competitors. With SpeedCurve, you can start making speed one of your competitive differentiators. Speed is especially important to mobile users who expect websites to load faster on phones than desktop, and are quicker to abandon pages that are too slow.
It’s great to have standard metrics that work across all web pages, such as onload time and start render. But those might not be the most important metric for your website. For Twitter the most important metric is time to first tweet. It’s likely that your website also has a custom metric that is best at measuring the user experience.
SpeedCurve is based on WebPageTest, the world’s best performance analysis tool. We deploy private instances of WebPageTest in Amazon data centers worldwide: US West, US East, Ireland, Germany, Japan, Singapore, Australia, and Brazil.
WebPageTest is an open source project with a public instance that people can use for free. It’s great for running tests one at a time, but testing multiple sites on a continuous basis isn’t supported because of the load it would create. WebPageTest also doesn’t support tracking and analyzing separate results. This is where SpeedCurve comes in.
SpeedCurve provides the capacity for you to run as many tests as you want. We store your results forever, and let you compare results over time, across regions, and in different browsers. This allows SpeedCurve to provide additional analyses focused on rendering performance such as Competitive Benchmarking, Responsive Design, and Third Party analysis.
Third party content (ads, widgets and analytics) account for 40-60% of web page content. For some websites, it’s the biggest performance problem on the page. Some third party snippets aren’t async and therefore can block the page from rendering. All of this makes the analysis and understanding of third party content important for maintaining a good user experience.
SpeedCurve’s customized Third Party analysis shows the performance impact for each third party on your website in terms of size, number of requests and total time. The unique Third Party Waterfall shows the impact each third party has on rendering, making it easier to identify third party content that is the most important to optimize.VIEW DEMO
SpeedCurve's Continuous Deployment dashboard helps you keep the development of your site on track with automated, continuous feedback on your performance pipeline. After you've deployed, use our API to tell SpeedCurve to do a custom analysis. The results are compared to the previous deployment and any performance regressions or budget violations are flagged in red, ensuring that you're able to fix performance problems before they reach production.
Track pixel level changes to your UX with visual diffs, filmstrip and video comparisons allowing you to easily spot any visual changes you may or may not have expected.VIEW DEMO
