A tool for developing responsive websites crazy-fast
Sizzy is a tool for developing responsive websites crazy-fast. It allows you to preview an url on multiple devices at once, filter the devices, zoom them in and out, and more.
The Sizzy Chrome Extension adds a button to your toolbar. When the button is clicked, it it's going to open the current url you're on in Sizzy. The extension also blocks "x-frame-options" headers so you can preview any site you want.
The extension is open sourced along the whole project. The entire code can be explored here: https://github.com/kitze/sizzy/tree/master/chrome-extension
