Simply the best! A must have. Keep going!
Awesome app! Top for me. Thanks a lot!
Awesome
This is a great extension with a lot of features for web designers. If you are a web designer, I recommend you to use it. This extension will help you to have a great design for different devices. The only problem I saw with this extension is that if the direction of a site is rtl, the layout of the extension elements will also be rtl and I have to convert the value of dir="rtl" to dir="ltr" myself through the Inspector to be able to use it. Thanks
Incredible! This tool is so well designed and it works incredibly well. I am an instant fan. I love the tooltip, inspect element and asset details. It makes identifying issues SO much easier.
WOW, I just stepped up my game with this extension. It's beautiful, easy to use and has the features I use on a regular basis.
Awesome! In my case Pixefy replaced 3 other extensions.
Used it for 8 minutes so far. Game changer
Love it - super intuitive & easy to use. Found user agent switch especially helpful.
This is magnificent. Very intuitive to use, just the right amount of features. I just hope it wont get ruined by ads or a limiting functionality when the beta is over.
