Squarespace Accessibility Checker by Kat ADA

About

Worried your website could draw an ADA accessibility complaint? Check any page in one click.

This free checker runs the open-source axe-core engine (plus a structural pass) against the page you're on, then groups what it finds the way professional evaluators read a report

• Errors, the definite WCAG failures
• Contrast, low-contrast text with the measured ratio and the colors involved
• Alerts, things worth a manual review
• Features, the accessibility features already present (alt text, form labels, page language)
• Structure, your heading outline and landmark regions
• ARIA, the roles and ARIA attributes in use

It also drops markers directly on the page so you can see exactly where each issue is, and every issue links to plain English guidance on how to fix it. Everything runs locally in your browser. No account, no sign up, and nothing about the pages you check leaves your computer.

Built by Kat ADA, a done-for-you web accessibility service for Squarespace. If you'd rather not fix things yourself, Kat ADA can scan your whole site and make the real source fixes for you, then send a dated record of the work. Run a free full-site scan at katadaapp.com.

Automated checks catch roughly a third to half of all accessibility issues, so a clean result is a good sign, not a guarantee. No tool can guarantee compliance or prevent a lawsuit, and this extension is not legal advice.
