Screen Ruler

TL;DR

A digital pixel ruler for your desktop that helps you verify if your CSS actually matches the design specs.

Who is this actually for?

Frontend developers and UI designers who are tired of opening DevTools just to check a basic margin or alignment.

The Good

• It is a focused utility that does not try to be an 'all-in-one platform' or use AI for things that do not need it.
• Provides instant visual feedback for spacing and dimensions across any application on your screen.

The Catch (Potential Downsides)

It is a bit of a niche tool that might feel redundant if you already live inside Figma or Chrome DevTools. You have to decide if one more utility icon in your toolbar is worth the screen real estate.
