Free ARIA Accessibility Checker
Validate ARIA roles, states, and properties across your site. Catch invalid ARIA usage that confuses screen readers and assistive technology.
How Our ARIA Accessibility Checker Works
Our ARIA checker validates every ARIA attribute on your page against the WAI-ARIA specification. It detects invalid roles, missing required properties (like aria-label on elements that need it), conflicting ARIA attributes, deprecated ARIA usage, and roles applied to elements that don't support them. It also checks that ARIA references (aria-labelledby, aria-describedby) point to existing element IDs.
The Impact of Aria Accessibility Checker Issues
Incorrect ARIA is worse than no ARIA at all. When ARIA attributes are misused, screen readers receive conflicting information, causing confusion and navigation failures for blind users. The first rule of ARIA is: if you can use a native HTML element with the semantics you need, do that instead. Our checker helps you find places where ARIA is broken or unnecessary.
Issues Our ARIA Accessibility Checker Finds
-
Missing required ARIA properties
Elements with ARIA roles that require specific properties. For example, a role="slider" without aria-valuenow, aria-valuemin, and aria-valuemax.
-
Invalid ARIA role values
Misspelled or non-existent ARIA roles like role="navigation" (should be role="nav") or made-up roles that assistive technology cannot interpret.
-
Broken ARIA references
aria-labelledby or aria-describedby pointing to IDs that don't exist on the page, leaving the element unlabeled for screen readers.
-
Redundant ARIA on native elements
Adding role="button" to a <button> element or role="link" to an <a> tag. These are redundant and can sometimes cause unexpected behavior.

Frequently Asked Questions
What is ARIA and when should I use it?
ARIA (Accessible Rich Internet Applications) is a set of HTML attributes that define ways to make web content more accessible. Use ARIA only when native HTML elements don't provide the semantics you need - for example, custom dropdown menus, tab interfaces, or modal dialogs built with <div> elements.
Can too much ARIA hurt accessibility?
Yes. The first rule of ARIA is to avoid using it when a native HTML element already provides the right semantics. Redundant or incorrect ARIA confuses screen readers and can make your site less accessible than using no ARIA at all.
How do I test ARIA on my site?
AccessGuard automatically validates all ARIA attributes against the WAI-ARIA specification. You can also test manually with screen readers like NVDA (Windows) or VoiceOver (Mac) to hear how your ARIA is interpreted by assistive technology.
