A Google Mobile-Friendly Test alternative

Google retired the Mobile-Friendly Test tool and the Mobile Usability report in December 2023, and now points site owners to Lighthouse. Lighthouse audits performance and best practices on one emulated phone. UICheck fills the gap the old test left: paste a URL and see whether the page actually works on phones, tablets and desktops, with every layout problem marked on a screenshot.

Choose Google Mobile-Friendly Test if

  • Lighthouse (Google’s suggestion) is the right tool for page speed and Core Web Vitals

Choose UICheck if

  • You want the old “is my page mobile friendly?” answer, with more detail
  • You need to see the problems on tablets and desktops too
  • You want a report to hand to a developer or client

Or use both

Use Lighthouse for speed and Core Web Vitals, and UICheck for layout: what visitors actually see on each screen.
