👉 Vision

The aim of page-speed.dev is to make it easy and straightforward to share web performance results. Currently, PageSpeed Insights and Core Web Vitals results are difficult to share, and and often shared via screenshot rather than via a link back to the source.

So:

• Results are cached for a day plus next request making subsequent requests fast and easy to share.
• undefinedMobile results are displayed. (Desktop results are too easy to get good results for and don’t adequately reflect a site’s performance.)
• undefinedCore Web Vitals are prioritised where available as these are a better measure of performance than Lighthouse/PageSpeed Insights results.
• undefinedMetrics in OpenGraph images to provide an easy way to share data.
• undefinedSVG badges to display Core Web Vitals metrics in GitHub READMEs or documentation.
