What is Usability Cat?
A quick overview of usability.cat and how it helps you build better web apps.
Usability Cat is an AI-powered tool that scans your website and gives you a clear, actionable report on how to improve it. Think of it as a code review, but for your UI/UX and security.
How it works
- Paste your URL — just drop in any web address
- We scan it — our AI checks your site on desktop and mobile
- Get your paw rating — a 1-5 paw score showing how your site stacks up
- Fix what matters — each issue comes with a plain-English explanation and a fix prompt you can paste into your AI coding tool
What we check
Usability Cat looks at two big areas:
UI/UX
- Typography and readability
- Color contrast and accessibility
- Layout and visual hierarchy
- Navigation clarity
- Form design and usability
Security
- HTTPS and security headers
- Common vulnerabilities (XSS, CSRF)
- Dependency health
- JavaScript security patterns
Who is this for?
If you're building web apps with AI tools (Cursor, Bolt, v0, etc.) and want to make sure your app doesn't look janky or have security holes, this is for you. No design degree required.
