This looks awesome! Just last week I had a handful of different browsers and devices open because I needed to make sure some new graphics we'd added to our site weren't slowing down load times for anyone. Won't have to do that ever again :)

Hello Product Hunt! First off, thanks to @kevin for hunting us. We built SpeedLab to help you test website speed across multiple browsers and devices at the same time. Traditionally, website speed tests were browser- and device- agnostic. This means you weren’t testing for the differences created by browser engines or device CPUs. With SpeedLab, we account for these differences—and give users insights into actual end-user experiences. You’ll get a cumulative score of your website’s speed across desktop and mobile browsers. We encourage you to take it for a spin. Questions and feedback are welcome!

Pretty neat! A one-stop shop to quickly test your website speed across browsers & devices.

Really great product! It's a modern tool to be able to see how your site is actually performing!

Noice. Device coverage looks neat.

Very cool!

Provides great coverage to test the websites.

game changer. users leave sites after just seconds if it doesn't load. no time to wait!

This is such a great tool!

Step aside manual process! Thanks @browserstack!
