UICheck vs Chrome DevTools device mode

Every developer starts with Chrome DevTools device mode: free, built in, and great for inspecting CSS at one screen size. But it shows one size at a time, only in Chrome, and finding a problem depends on scrolling every page at every size. UICheck does that sweep automatically and reports what it finds.

Choose Chrome DevTools device mode if

  • You are fixing CSS and need to inspect elements at one size
  • You want to emulate network speed or sensors

Choose UICheck if

  • You want every size checked without scrolling each one
  • You need Safari and Firefox too
  • You want a list of problems to fix or hand over

Or use both

Let UICheck find the problems, then open DevTools at that width to fix them; each finding names the element and the width.
