ARIA Checker
SiteTend ARIA
Find invalid ARIA, missing accessible names, role conflicts, and common interactive-element accessibility risks before publishing.
Your input stays private.Markup is analyzed in your browser.
Paste component markup
Add HTML, a fragment, or rendered component markup.
Review accessibility semantics
Start with invalid semantics and unnamed controls.

Paste markup and select Analyze ARIA.
How to use ARIA
Start with semantic HTML
Use native elements first, give every control a clear accessible name, and keep states synchronized with behavior. Confirm static findings using keyboard and assistive-technology testing.
Questions
ARIA Attribute Checker FAQ
What does the ARIA Attribute Checker analyze?
It checks common ARIA names and values, roles, detectable accessible names, hidden interactive content, redundant semantics, and landmark indicators.
Should ARIA replace semantic HTML?
No. Native HTML elements should provide semantics whenever possible. Use ARIA only to fill accessibility gaps that native HTML cannot express.
Can this checker prove that a component is accessible?
No. Static analysis cannot verify keyboard behavior, focus order, browser accessibility-tree output, announcements, or real assistive-technology use.
Does SiteTend store pasted markup?
No. The checker analyzes markup locally in your browser and excludes it from analytics.
Apply the result
From finding to verified fix
Interpret the finding
Correct invalid roles and values, but prefer native semantics before adding ARIA. Passing static checks does not establish accessibility.
Common causes to inspect
- ARIA copied without the matching interaction pattern
- Controls missing an accessible name
- Roles or states that conflict with the underlying HTML element
Practical next steps
- Replace unnecessary ARIA with native elements
- Give controls accurate names, roles, states, and properties
- Verify the accessibility tree, keyboard behavior, and assistive-technology output
What this check cannot prove
Static markup cannot confirm runtime state synchronization, focus behavior, accessibility-tree output, or real assistive-technology use.
