Helium is based on the popular Selenium framework	for web browser automation. Selenium is great! It is fast, stable, actively developed and supports a huge variety of browsers and operating systems. Unfortunately, it is also difficult to use. This is where Helium comes in.
Helium inherits Selenium's speed, stability and browser support.
You can freely mix calls to Helium with any Selenium 2 code.
At the same time, Helium is much easier to use than Selenium.
Another benefit is that you can use Helium with any existing Selenium infrastructure. For instance, you can use Helium with Sauce	and BrowserStack. These services offer browser virtualization in the cloud: You can say "start a browser on an iPhone with iOS 7" and get a Selenium interface for controlling this browser. Since the interface is Selenium, you can also control this browser using Helium. This makes it very easy to run tests across browsers or speed up test execution by parallelization.
Run virtually any browser/OS combination in the cloud with Helium.
