How to Simulate Devices With GTmetrix
GTmetrix allows you to test your page’s performance on mobile by modifying the screen resolution, user agent, and device pixel ratio to each device’s technical specifications.
Advanced Options for PRO (formerly Developer Toolkit)
GTmetrix has a ton of great features available in our Basic account (Sign up if you haven’t yet – it’s free!) – but for those who wanted more advanced insights, we’ve listened to your feedback and created the Developer Toolkit – a bundle of features that can help you get the most out of GTmetrix.
