So why?
Why Choose Pixefy for Your Website Reviews?
Reviewing and testing websites can be overwhelming, especially for those who built them. After trying various tools and extensions to speed up the process, none met our need for speed. That’s why Pixefy was created – with a focus on accelerating testing and audits efficiently
Working with web projects 10+ years I can say this tool makes testing so much faster! Literally in minutes I can check responsiveness and other parameters and feedback them to the tech team. Love it!

A handful extension from a QA perspective. It allows me to use different user agents quickly and go through different device views of web pages.

It's a very helpful tool. I can view now in one window how my photos on the website will look on phones, tablets, and so on. With full-page screenshots that I love. The user interface is intuitive, making it easy to use even for those less familiar with tech. Highly recommended for its efficiency and simplicity.

I just installed and immediately love it. I was looking for an alternative to responsive viewer which i was previously using since they just updated their software and the whole look and feel became rubbish, this is far more superior. Hope in the future the update wont disrupt the design and i wont be asked to pay for nonsense.

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

This Chrome extension for responsiveness testing is a must-have for developers and QA engineers alike. It streamlines the process of ensuring a website's adaptability across various devices and screen sizes. While there’s room for a few advanced features, it delivers exceptional value in its current form.
