UX HeatGrid

About

UX HeatGrid is a real time heatmap and layout analysis tool that shows you where attention is naturally drawn on any web page directly in your browser, without any setup.

As you scroll and interact with a page, UX HeatGrid builds a live heat map that reveals which areas are getting the most focus and which parts feel visually crowded, unbalanced, or easy to overlook. It also scores the page’s overall design quality by evaluating content density, spacing, visual complexity, and readability, giving you an instant, objective snapshot of how the layout is performing.

Designed for designers, developers, UX researchers, and product teams who want fast, reliable layout feedback without leaving the page or waiting for user data to accumulate.
