Site speed monitoring built for ecommerce

Blackbird monitors how quickly your ecommerce site loads for real users and tracks your sales data to show how site speed affects your revenue.

Track Lighthouse data

Compare your site speed to competitors using data from Lighthouse. Blackbird automatically stores data like Time To Interactive and Largest Contentful Paint so you can measure your web performance against others.

Track Lighthouse Data

Measure site speed for real users

Not everyone sees the same loading time for your site. People on fast devices and better connections will have a better experience than those on weaker devices and slower connections. Blackbird measures the actual page load time for every visit to your site, so you get data you can trust.
