UI Design Analyzer
Live this weekInstant visual design analysis from screenshots
About
UI Design Analyzer is a browser‑based tool that lets you upload a screenshot of a website, app, poster or packaging design and instantly receive a detailed visual‑design report. It evaluates eight key criteria—color harmony, spacing, alignment, consistency, hierarchy, typography, corner rounding and icon consistency—and assigns a weighted score out of 100. The report also offers specific improvement recommendations. Because it runs in the browser, no registration or installation is required.
The case
Who it is for
UI designers, product designers and front‑end developers who need rapid visual quality checks for website, app or marketing graphics without a full design system.
What is broken today
Before a dedicated visual‑design checker, designers had to manually inspect screenshots for color harmony, spacing, alignment, and other visual cues, or rely on fragmented tools that covered only a few aspects. This process was time‑consuming, inconsistent, and often required a design system or developer to validate each element, making it hard to catch visual flaws early in the workflow.
What it does about it
UI Design Analyzer lets designers upload a screenshot in JPG, PNG or WebP. The browser‑based engine extracts visual signals such as contrast, padding, grid alignment, typography scale and icon consistency. It scores each of eight criteria, combines them into a weighted total, and outputs a report with a single UI score out of 100 plus specific improvement recommendations.
Why not the obvious alternative
Unlike generic design tools, it focuses solely on visual quality, offering a single weighted score and actionable feedback across eight criteria, runs entirely in the browser without login, and supports multiple formats (web, mobile, poster, packaging) with mode‑specific weightings.
