# Experimental Chromium features

Polypane is a browser for developers, so it comes with some experimental Chromium features turned on by default. This means you can use Polypane to try out upcoming features before they make their way into regular browsers!

## Enabled features

Below are some highlights of the features that are enabled by default in Polypane. You can see the full list of enabled features on our page on [Experimental Platform features](/experimental-web-platform-features/) .

### Prefers-reduced-data

Prefers reduced data is a new media query that lets visitors signal they want to preserve data. You can emulate it in Polypane by going to [the emulation section above a pane](/docs/emulation/) and toggling "prefers-reduced-data" to "reduce".

> We wrote an article about what you can do with prefers-reduced-data, read that here: [Creating websites with prefers-reduced-data](/blog/creating-websites-with-prefers-reduced-data/).

### Test features

In addition to the experimental features, Polypane also enables a number of features still in test:

*   CSSUserSelectContain
*   CSSCaretAnimation
*   CSSColorContrast
*   CSSCornerShape

These might not be fully implemented yet, but are available for testing.
