Today our friends at Cloud9 have released a brand new version of their powerful Cloud9 Development Environment, the web-based IDE that gives you unlimited flexibility to develop and test your applications directly from your browser. As part of this release, we're excited to announce an integration that we've been working on together for a while---the ability to instantly check out the site or app you're developing in any desktop or mobile browser that Sauce Labs supports, directly in the Cloud9 interface. Cloud9 has always given you the ability to easily preview the site you're working on using your current browser. For example, in the screenshot below, you can see the preview window conveniently located where you can work on your code and see the changes reflected immediately: Our integration simply adds another option to the drop-down menu to the right of the URL bar in the preview pane. If you click "Browser", you'll see additional options (it even remembers the last four browsers you used for quick access): You can select any of our desktop or mobile browsers right from this interface. And if you're already logged in to Sauce Labs, you'll see the browser loading immediately. Now you can see whether your "responsive" website actually works as expected on, say, an iPhone Simulator, without ever leaving your IDE: We think this integration opens up a ton of possibilities for your development workflow, and are proud to be a part of the web-based IDE revolution with Cloud9. Check it out and let us know what you think!
