Website accessibility checker.

What this tool checks

Deterministic, code-based checks parsed straight from your markup: images missing alt text (WCAG 1.1.1), form fields with no associated label (1.3.1 / 4.1.2), missing page language (3.1.1), a missing or empty title (2.4.2), a missing or duplicate h1 and skipped heading levels (1.3.1), empty or generic links and icon-only buttons (2.4.4 / 4.1.2), positive tabindex (2.4.3), and a missing skip-to-content link (2.4.1). Findings are grouped by impact (critical, serious, moderate).

Why accessibility matters (and what it is not)

Under the ADA, courts and the Department of Justice generally treat WCAG 2.1 Level AA as the standard for accessible websites, and thousands of demand letters and lawsuits go out every year, many over the exact issues above. Fixing them widens your audience, helps SEO (clean semantics and alt text are signals search engines use), and reduces legal exposure. But be clear-eyed: passing an automated scan is not the same as being compliant. Automated tools catch a portion of issues. The rest, like whether your alt text is actually meaningful or your page works fully by keyboard, needs a human.

How we are different from the "free scan" widgets

Tools like accessiBe's accessScan and UserWay run a free scan and then push you toward a paid accessibility overlay widget. Those overlays do not fix your underlying code, and they have not stopped lawsuits. In 2025 the FTC fined accessiBe one million dollars for deceptive accessibility claims. Our checks are honest static checks mapped to WCAG with specific fixes, with no widget to sell you, no gated findings, and a clear label that this is an automated check, not legal advice.

Pro tips

• Start with the critical and serious findings (missing alt text, unlabeled fields, empty links and buttons), they affect the most users and show up most in lawsuits.
• A placeholder is not a label. Every input needs a real <label for="id"> or an aria-label.
• Empty alt (alt="") is correct for purely decorative images, it tells screen readers to skip them. Only meaningful images need descriptive alt.
• Rewrite "Click here" and "Read more" links to describe their destination, many people navigate by jumping link to link.
• Add a skip-to-content link as the first focusable element so keyboard users can bypass the menu.
• Treat a clean automated result as a floor, not a finish line. Follow it with a real keyboard test and a manual audit.
