Never hassle with browsers again.

Compati is a Chrome extension that allows you to test different browsers from the comfort of your own.


Web browsers come in all shapes and sizes, and from all ages. While we as developers love to use cutting-edge CSS properties to make our websites look awesome, some of these properties might not work as intended, or at all, in different or older browsers.

Chrome 55: the gradient and circular section render perfectly, just as expected.

Firefox 3.6: falls back to a square border and no gradient, completely ruining the image.

Meet Compati.

Compati is an easy-to-use Chrome extension which allows you to simulate the browser rendering engines of different browsers, to let you visualize how your website reacts to different browsers and code accordingly.


Compati is free and available to all users of Google Chrome.
