SIX DIMENSIONS

Every scan, measured across six axes.

A single score lies. Six don't. Vizlint gives you a breakdown granular enough to prioritize — and comprehensive enough to trust.

THE FOUNDER
I've lived this problem on both sides — as a designer reviewing developer implementations, and as an engineer shipping UI without a quality check.

After the AI coding explosion, that gap became a chasm. Vizlint is the tool I needed and couldn't find.
