A tool for testing responsive websites crazy-fast
Sizzy is a tool (website) created by Kitze to speed up the development process of responsive websites.
Note: The tool uses iframes to render the various views. If you are testing your own site(s) ensure you do not have the “X-Frame-Options” header set to “sameorigin”.
If your site, or any other site you are trying to view, has the header set, you will not be able to use this tool.
There are various ways you can use the tool.
