Is this WCAG / RGAA Accessibility Checker completely free?

Yes. The Priygop accessibility checker is 100% free with unlimited scans, no registration required, and full access to issue breakdowns and JSON report downloads.

What is the difference between WCAG 2.1 and WCAG 2.2?

WCAG 2.2 is the latest official recommendation from W3C. It retains all previous criteria while adding 9 new success criteria focused on mobile users, individuals with low vision, and people with cognitive disabilities (such as minimum touch target sizes of 24×24px, focus appearance, and avoiding redundant form inputs).

How does the scanner test my website safely?

The scanner launches a sandboxed, isolated browser session, navigates to your public URL, renders the DOM, and executes the industry-standard axe-core testing engine. It enforces strict SSRF protections: internal, local, private, and cloud metadata IP ranges are blocked.

Does an automated pass prove my website is 100% legally compliant?

No. Automated tools detect between 30% and 50% of WCAG criteria. Certain criteria (such as whether alt text makes sense in context, keyboard focus management in complex modal dialogs, or video captions) inherently require human evaluation.

What does the 'Needs Manual Review' status mean?

Axe-core flags elements that require human perception to decide compliance. For example, text rendered over complex multi-color CSS gradients or background images where a computer cannot deterministically measure exact contrast.

Can I scan websites that are behind a login or firewall?

No. To protect private infrastructure and avoid credential exposure, the scanner only audits publicly accessible web pages over standard HTTP and HTTPS.

What is Website Accessibility Testing?

Website accessibility (often abbreviated as a11y) ensures that digital products, content, and interactive interfaces can be easily navigated, understood, and used by everyone, including people with visual, auditory, motor, or cognitive disabilities. Accessibility testing evaluates page structure, contrast, assistive technology hooks, and interactive controls against internationally recognized technical standards.

What is WCAG (Web Content Accessibility Guidelines)?

The Web Content Accessibility Guidelines (WCAG) are developed by the World Wide Web Consortium (W3C) Web Accessibility Initiative (WAI). They are organized under four core principles:

Perceivable: Information and user interface components must be presentable to users in ways they can perceive (e.g. text alternatives for images, clear contrast).
Operable: User interface components and navigation must be operable (e.g. keyboard accessible, sufficient time to read, no seizure-inducing flashes).
Understandable: Information and the operation of the user interface must be understandable (e.g. predictable navigation, clear form input labels).
Robust: Content must be robust enough to be reliably interpreted by a wide variety of user agents, including assistive screen readers.

WCAG 2.2 is the latest official W3C standard (published October 2023), introducing criteria like Focus Not Obscured (2.4.11), Target Size Minimum (2.5.8), and Redundant Entry (3.3.7).

What is RGAA (Référentiel Général d'Amélioration de l'Accessibilité)?

The RGAA 4.1 is the official French national accessibility reference method, mandated for public sector services, state agencies, and designated large private companies in France. It translates European standard EN 301 549 and WCAG criteria into 106 verifiable criteria covering images, frames, colors, multimedia, tables, links, scripts, mandatory elements, structuring, presentation, forms, navigation, and consultation.

What This Automated Scanner Detects

Missing Image Alt Attributes: Graphics and photos lacking text alternatives needed by screen readers.
Form Control Labels: Text inputs, checkboxes, and radio buttons missing associated <label> or aria-label tags.
Insufficient Color Contrast: Text that fails the 4.5:1 luminance contrast ratio against its background.
Invalid ARIA Markings: Misspelled ARIA attributes, non-standard roles, or orphaned aria-describedby references.
Heading Hierarchy Skips: Jumps from <h1> directly to <h3> without an intermediate <h2>.
Buttons and Links Without Names: Interactive icon-only buttons with no readable accessible name.
Missing Document Language: Missing lang attribute on the root <html> element.
Duplicate Element IDs: Conflicting HTML IDs that break label bindings and screen reader focus tracking.

What Automated Scanners Cannot Detect (Why Manual Testing is Required)

Automated accessibility scanners reliably check approximately 30% to 50% of all WCAG success criteria. The remaining requirements depend on human context and judgment:

Whether image alt text accurately conveys the true meaning and intent of the photo.
Whether keyboard tab order is logical and intuitive through multi-step dialogs.
Whether captions and transcripts for live and pre-recorded videos are accurate and synchronized.
Whether error validation messages clearly guide users with cognitive disabilities.

Priygop's scanner is an automated diagnostic tool to accelerate compliance, but should always be combined with human manual audits.
