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
A helpful extension from a QA perspective. It allows me to use different user agents quickly and go through different device views of web pages.
Speaking as a designer, this tool really helps me out with checking website responsiveness. It's so easy to use, and I don't have to mess around dragging browser windows anymore. Saves me a ton of time.
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!
We’ve implemented a wide range of features, with more exciting updates on the way. Stay tuned!
