Frequently Asked Questions

We’ve gathered answers to some of the most commonly asked questions

Does Pixefy extension accurately render as real devices?

Our extension uses user agent strings aiming to display pages nearly identical to actual devices, although it may not provide 100% accuracy.

Can the extension be used on all websites?

Due to security restrictions from Google's Manifest V3, some websites may not be accessible with the extension. However, the majority of sites are.

Does Pixefy render the page with the same engine as the browser?

Yes, Pixefy is built as extension for browser and uses as its native rendering engine. For now we support Chrome, but soon we will release an update for all other popular browsers.

Is a Paid Version Coming After the Beta?

Pixefy will continue to be available for free, but we will indeed launch a paid version after the beta period.

Will I be able to cancel paid version at anytime?

Yes, you will be able to cancel at any time, no questions asked. However, we would highly appreciate it if you could provide us with some feedback when you do, as it will help us improve.

How do I update the extension?

The extension automatically updates to the latest version once you restart your browser, if an update is available.

How about privacy?

To run our extension we require some permisions, but don't worry, we take privacy very seriously. Your data stays with you.
