We’re excited to announce the release of our 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.
We’re including the Developer Toolkit in our Bronze, Silver and Gold plans, and also offering it as an add-on to PRO custom plans.
Read on to discover what’s included:
See how your website could display and load on a simulated device. We’ve pre-selected combinations of user agents, screen resolutions, and device pixel ratios that best represent popular devices.
Now you can test your page’s responsive performance on simulated iPhones, iPads, Android phones, tablets and more.
Be sure to analyze your site with a wide variety of devices to ensure consistent performance for any and all your visitors.
Monitoring and API access is also available for Simulated Devices in our 7 global test regions.

*Hardware performance is not emulated. Actual loading behaviour may differ on actual device. Learn more here
User Agent Override
Enter your own User Agent (UA) string for GTmetrix to present to your server. This will automatically populate depending on the chosen Browser Options or Simulated Devices.
Advanced users can choose to override the User Agent for our Browser Options – however you cannot change the UA string if you’ve selected to test with a Simulated Device.
Screen Resolution and Device Pixel Ratio (DPR)
The Developer Toolkit allows you to select from a list of the most common screen resolutions for GTmetrix to load your page in.
In addition, you can also input your own Device Pixel Ratio (DPR) – or dots per pixel (dppx) – to ensure an accurate display. Orientation can also be toggled to portrait or landscape mode.
Responsive designs will benefit the most from tests with varying screen resolutions, so be sure to test out your site in different resolutions to ensure it’s optimized across all – or choose which devices matter to you most with our Simulate Device feature.
Great for development and staging sites, analysis for before/after server migration, etc. Input your own host and IP address for GTmetrix to use when analyzing your page.
Note: Sites using https:// and SSL will still require the newly pointed server to have their SSL certificate properly set up, or GTmetrix will be unable to analyze.

You can now save all of your Analysis Options as a preset for faster and more convenient testing.
Analysis Presets are accessible in the Analysis Options dropdown on the Dashboard for quick access to your preferred test settings.
For even more convenience, Analysis Presets are also available on the Dashboard Analyze button as a dropdown. Just enter a URL in the analysis field and select a preset from the dropdown to immediately test with your desired options.
