Free Keyboard Accessibility Checker
Find keyboard navigation barriers on your site. Detect focus traps, missing focus indicators, and interactive elements that keyboard users cannot reach.
How Our Keyboard Accessibility Checker Works
Our keyboard checker evaluates your page for keyboard accessibility. It detects elements with click handlers but no keyboard equivalent, missing or suppressed focus indicators, tabindex values that disrupt natural tab order, focus traps where keyboard users get stuck, and interactive elements that are not reachable via keyboard. It also checks for proper skip navigation links.
The Impact of Keyboard Accessibility Checker Issues
Keyboard accessibility is essential for users who cannot use a mouse - including people with motor disabilities, blind users, and power users who prefer keyboard navigation. If any part of your site cannot be operated with a keyboard alone, you fail a Level A WCAG requirement. Keyboard traps (where users get stuck in a component) are among the most severe accessibility failures.
Issues Our Keyboard Accessibility Checker Finds
-
No visible focus indicator
Interactive elements that show no visual change when focused via keyboard. Users cannot tell which element is currently selected without a focus ring.
-
Click-only interactions
Elements with onclick handlers but no keyboard event handlers. Div and span elements used as buttons that keyboard users cannot activate.
-
Positive tabindex values
Elements with tabindex values greater than 0 that override the natural tab order, creating unpredictable navigation for keyboard users.
-
Focus traps
Modal dialogs, dropdown menus, or carousels that trap keyboard focus with no way to escape. Users must reload the page to continue.

Frequently Asked Questions
Why is keyboard accessibility so important?
Keyboard accessibility is a baseline requirement because many assistive technologies - including screen readers, switch devices, and voice control - translate their input into keyboard commands. If your site works with a keyboard, it likely works with most assistive technologies too.
How do I test keyboard navigation?
Put your mouse away and try using your site with only the keyboard. Press Tab to move forward, Shift+Tab to move backward, Enter or Space to activate buttons and links, and Escape to close dialogs. If you get stuck anywhere or cannot see where focus is, those are keyboard accessibility issues.
What is a focus trap and when is it acceptable?
A focus trap keeps keyboard focus within a specific area. It is acceptable (and required) inside modal dialogs - focus should cycle within the modal until it is closed. It is never acceptable on a regular page where users cannot escape a component.
