ADJUSTABLE MOBILE VIEW

Duo gives you a typical 'mobile' view using a 320px wide pane, which is adjustable to whatever size suits your needs. A simple dimension indicator is displayed to help you get the perfect size.

TABLET / DESKTOP VIEW

In your second pane, browse the web using any width you'd like.

SYNCHRONIZED BROWSING

Navigating in either pane updates the other. No need to reload layouts to view pages at different sizes.

WEBKIT DEV TOOLS INCLUDED

Duo has everything you need to make sure your design is doing what it should. Debug code in either pane.

CONVENIENT KEY COMMANDS

Duo includes tools for clearing your cache and getting rid of those pesky cookies via standard key commands.

HANDY BOOKMARKLET

Use the convenient bookmarklet in your other browsers to push a site over to Duo.

WHAT IT ISN'T

Duo is designed for Responsive Web Design, not for user-agent sniffing of mobile versions of sites. Duo currently only refreshes both views for GET requests. It's probably not a good fit for your POST refresh heavy project, although we are actively looking at ways to accommodate this.
