Sizzy

The browser for designers and developers to test responsive sites

About Sizzy

Sizzy displays a website across many simulated devices simultaneously with synchronized interactions, screenshots, and debugging tools in a polished interface. Agencies present and test client sites across devices from a single window. In practice, it is the kind of single-purpose tool people keep bookmarked for a recurring job, and users usually compare it on speed, limits, privacy handling, and whether it works without registration.
