Early in 2010, Apple announced it would not support Flash in its products. Shortly after, Microsoft signaled the end of Silverlight (a Flash-like plug-in) and stated that Internet Explorer 10 would no longer support any browser plug-ins, including Flash. The industry was clearly moving toward HTML5. New tools like Adobe Edge were introduced to support the shift, yet no broadband speed tests had embraced HTML5. Most still relied on Flash or Java plug-ins.
In December 2011, we launched the first HTML5-based broadband speed test. SpeedOf.Me is a pure HTML5 and JavaScript solution that relies entirely on browser-native technologies. It was built to work seamlessly across all HTML5-supported browsers, including desktops and mobile devices like iPhone, iPad, Android, and Windows. No plugins, no downloads. Just a simple, accurate speed test in your browser.
