Tool for testing your responsive web designs

Hey fellow hackers,

ScreenDump is a tool that I've been working on recently, it lets you test responsive web design by showing you previews of your website in any size. Feel free to share your feedback :)

The API for generating screenshot is powered by Capture (https://capture.techulus.in) which is my flagship product.

Cheers!
