How to Test with Legacy GTmetrix Reports

Need to test with Legacy GTmetrix Reports? No problem!

We understand that the move to Lighthouse-based reports is a big change and that some users may want to use Legacy Reports for various reasons.

If you’re not ready to make the switch to Lighthouse reports yet, you can still use the Legacy GTmetrix Reports by following the instructions below:

Visit your Account page (located in the top right hand corner), scroll to your Analysis Options section and toggle the ‘Enable Legacy Reports’ option. Hit “Save Settings”.

Your Account page is located in the top right hand corner.

Enable Legacy Reports in the Analysis Options section.

Once this is done, you will be able to enable Legacy Reports as an Analysis Option in your Dashboard Dropdown.
Enable Legacy Report in the Analysis Options on your Dashboard or GTmetrix Report Page Settings.

You can also enable Legacy Reports on your Page Settings on a GTmetrix Report.

Lastly, if you wish to only use Legacy Reports, enabling ‘Default to Legacy Reports’ ensures that GTmetrix tests will only generate Legacy Reports.

Only generate Legacy Reports by enabling “Default to Legacy Reports” in your Account page, Analysis Options section.


You’ll see an “L” icon on the “Analyzing…” page when you have initiated a test enabling the Legacy Report.

An “L” icon denotes the generation of a Legacy GTmetrix Report.
