Would be great to see Android too. I have most of these devices but always have to wonder how it looks on Android while working.

Cool! After entering a website it would be great if you could generate a link i can sent to clients for them to view the result. At the moment it's always "er.php".

This is seriously my new favorite thing. I've used it a dozen times today as we're testing a pretty massive rework of some stuff on our site- love the simplicity of being able to do 1 simple task really quickly and easily.

This is exactly what I need. I could not have found this at a better time. Thanks!

After entering the website, popping in a link and clicking start, it loads er.php and then everything is pushed to the left off view.. see http://grab.by/NZHm -- you can see a sliver of each section when scroll on the left hand side.

I like these things (I created something similar). Recommended updates: - It should definitely have a query string or a hash at the end to make it shareable - Add some error calculation for XFRAME Options (add google.com into the URL to see what I mean) This is still much more suited to providing a general overview to people about what you mean when you say responsive, or as a screenshot tool for your portfolio. Testing is next to useless using iframes so you're much better off with actual devices or something like browserstack.

Oh man, if only this picked up on user agents.

Why don't just use the Responsive Design Mode in Safari (Alt+Cmd+R)? Other browsers have similar features too.

Showing the website in an Iframe does not help much.. The actual design in the Device may vary.. There are many similar sites showing in iframe.. No idea what's the use of creating yet another one? or just an exercise?

All I'm getting is a white screen when I enter a URL.

A very nice thought. Since it's locally executed it runs JS and takes sessions into account, so you can test pages that require authentication. Maybe that's why it can't be shareable...

For some reason, it shows the Desktop version everywhere though if you actually check the website on Mobile it loads up the Mobile version of http://PhoneRadar.com Is something missing?

This is great! Would love if their were a few other common resolutions in there and the ability to 'share'

love the simple approach. Some of these are co annoying to use.

By the way Safari has that feature built in! Develop > Enter Responsive Design Mode :)

wow. this should be helpful :)

This is amazing!

A killing feature would be to replay an action done on 1 device to all the other views. No more wasting time in testing UX for different devices.

The browsers themselves render such tools of little use nowadays, but nicely done!

Does it have any "Score" index or recommendations to make your site better?
