In a post last week in the Adobe blog, the company announced the Adobe Shadow Labs Release 1 — a utility for mobile web designers and developers that is aimed at allowing real-time previews and testing on multiple devices as you design.

You can download the free utility from Adobe now. The package includes:

• a desktop app for Mac or Windows
• Shadow clients for both iOS and Android
• a Google Chrome browser extension

They recommend that you start by watching the Shadow demo video, which is posted in the blog announcement.

The early word seems pretty positive, as Webmonkey.com’s Scott Gilbertson writes:

It’s no secret that, while responsive design allows developers to easily target a wide range of screen sizes, it adds a considerable amount of work to the development process. But with Shadow mirroring your website across dozens of devices at the same time, testing becomes simple and easy.
