Muy buena extension para desarrolladores web. Se diría que imprescindible.
Amazing tool for web devs <3
It doesn't work properly :((
Excellent tool, I'm going to be using this A LOT.
Simple, clean UI and really helpful addition to webdesigner workflow. I bought appsumo ltd - for the price of 19$ it already paid me off after few days :)
Pixefy is a simple and useful extension for quickly checking responsive layouts across different device sizes. It saves time for developers, but a few users mentioned occasional bugs or feature limitations.
Pixefy is a simple and effective tool for quickly checking website responsiveness across multiple devices, helping developers ensure a seamless user experience.
I installed Pixefy in Chrome, viewed a website, and clicked on the P icon. Nothing happened. I expected something, at least an introductory welcome and instructions.
Great extension, saves time and works perfectly.
