Questions on file
- How is GTmetrix different from Google PageSpeed Insights or Lighthouse?
- GTmetrix uses the same Lighthouse engine under the hood but goes further, testing from real browsers in real locations worldwide, tracking performance trends over time, and providing deeper insights into what exactly is slowing down your site.
- Can I test my site from different locations and devices?
- Yes. GTmetrix lets you test from 28 global test locations, simulate 55+ devices and variants, throttle different connection speeds, and modify parameters so you can see how real visitors in different regions experience your site.
- Does GTmetrix monitor my site automatically or do I have to test manually?
- Both are supported. You can run one-off tests anytime or set up scheduled monitoring so GTmetrix automatically re-tests your site and alerts you if performance drops.
- Is there a free plan or do I need to pay?
- GTmetrix offers a free trial so you can try it with no commitment or credit card required. Paid PRO plans unlock more frequent testing, more test locations, monitoring, and historical tracking.
