Online Accessibility Test — Analyze Your Site for Free

How does an online accessibility test work?

An online accessibility test analyzes your website to detect barriers that prevent certain users from accessing your content. Since the European Accessibility Act (EAA), compliance is both a legal and moral imperative. These barriers affect people with disabilities — visual, motor, cognitive, auditory — as well as users of assistive technologies like screen readers, alternative keyboards, or braille displays.

Concretely, an online test loads your page in a real browser and runs a series of automated checks. The quality of the test depends on the number of criteria checked and the depth of analysis. The simplest tools (WAVE, Lighthouse) only test static HTML, covering about 30% of accessibility issues. Scrutia goes further by testing dynamic interactions.

The limits of purely static tests

Most free online accessibility testing tools work by static analysis: they read your page's HTML code and check for the presence of certain attributes (alt on images, labels on forms, ARIA roles). This is useful, but insufficient.

The most serious accessibility issues are often dynamic. A menu that doesn't open with the keyboard, a modal that traps focus, a form whose errors aren't announced to screen readers — these issues can only be detected by actually interacting with the page. That's exactly what Scrutia does.

What automated tools detect

Automated analysis tools like Scrutia are particularly effective on the following WCAG criteria:

• ✓Keyboard navigation (Operable) — Tab traversal, keyboard traps, tab order, visible focus
• ✓Interactive components (Robust) — menus, tabs, modals, accordions, buttons, with ARIA pattern verification
• ✓Contrasts (Perceivable) — text/background contrast ratios per WCAG AA thresholds
• ✓Structure (Understandable) — heading hierarchy, landmarks, page roles
• ✓Forms (Understandable) — labels, required fields, error messages, autocomplete
• ✓Presentation (Perceivable) — reflow at 320px, zoom at 200%, orientation

Scrutia: a complete accessibility test, not a simple scanner

Scrutia sets itself apart from basic scanners with three innovations. First, our engine drives a real browser (Chromium) and interacts with your page as a user would: navigating by keyboard, opening menus, filling forms. Second, the analysis is guided by AI, reducing the false positive rate below 5%. Third, for each issue detected, Scrutia generates fix code adapted to your site, ready to paste.

The result is a pre-audit that covers 100% of the WCAG 2.1 AA criteria, with a professional PDF report that you can forward directly to your developers or management.
