# Polypane ❤ Tumult Hype. New integration

[Tumult Hype](https://tumult.com/hype/) lets you create beautiful, responsive HTML5 animations and web content.

When you preview your design by clicking the 'preview' button in Hype and selecting Polypane, it will automatically open the viewports you've specified in Hype so you get the full overview with just a single click. If you click the preview button again Polypane focuses and reloads your existing tab, even if you've made changes to that tab. This is the ideal way to test your Tumult Hype creations on multiple screen sizes.

Check out the video for a quick walkthrough:
