They don’t tab through your page. They don’t open dialogs. They don’t navigate forms. And because of that, they miss critical issues.</p> <p>Tabnav is different.<br> It’s a free web accessibility checker built to simulate real user interaction—especially keyboard navigation—so developers get reliable, actionable insights instead of generic warnings.</p> <p><strong>Why Tabnav?</strong></p> <p>Accessibility errors rarely live in your markup.<br> They show up in behavior:</p> <ul> <li>Buttons that look clickable but aren’t reachable with a keyboard</li> <li>Hidden elements that accidentally receive focus</li> <li>Dialogs that trap users</li> <li>Missing or confusing focus indicators</li> <li>Images or icons without accessible names</li> <li>Structure that confuses screen readers</li> <li>Unexpected new windows</li> <li>Form fields missing proper labels</li> </ul> <p>Tabnav acts like a real user, then generates a clear report with the exact code-level issues to fix.</p> <p>What Tabnav Checks (Summarized)</p> <p><strong>Content &amp; Media</strong></p> <p>Ensures your images, icons, SVGs, background graphics, and media elements have proper accessible names and alt text.<br> It also checks zoom and readability to confirm content can scale up to 200% without breaking.</p> <p><strong>Keyboard &amp; Focus</strong></p> <p>Simulates actual keyboard navigation to detect issues such as:</p> <ul> <li>Missing focus outlines</li> <li>Broken tab order</li> <li>Invisible elements receiving focus</li> <li>Skip link behavior</li> <li>Dialog keyboard traps and missing exits</li> <li>Predictable focus movement</li> </ul> <p>These are the problems most automated tools never catch.</p> <p><strong>Page Structure</strong></p> <p>Checks whether your HTML uses meaningful headings, landmarks, and semantic roles so assistive technologies can interpret the page correctly.</p> <p><strong>Built for Developers</strong></p> <p>Tabnav explains why each issue matters and links to short educational notes from Tabnav Academy.<br> Every finding includes:</p> <ul> <li>The exact element causing the issue</li> <li>The WCAG requirement it relates to</li> <li>How to fix it</li> <li>Clean code examples</li> </ul> <p><strong>Try Tabnav for Free</strong></p> <p>You can run a full accessibility scan in seconds—no account needed.</p> <p>👉 <a href="https://tabnav.com/accessibility-checker" rel="noopener noreferrer">Scan your website for free with Tabnav</a></p> <p>We’d love to hear your feedback.</p> a11y webdev checker userexperience
