Accessibility Scanner

Honest, instant WCAG accessibility audit of any page. See exactly what's broken, outlined right on the page. No login, no email.

Accessibility Scanner runs a real WCAG accessibility audit on whatever page you're viewing. Click the button and it injects axe-core, checks the page, and outlines every failing element right where it is, with a severity badge, plus a summary of issues by impact. It runs entirely in your browser: no login, no email, no account, and nothing about the pages you scan ever leaves your machine. It is honest about limits too. Automated testing only covers the machine-checkable part of WCAG, so it flags what still needs a human and never claims you are "compliant." For saved history, multi-page audits, and monitoring, there is a hosted version at accessibilityscanner.app, but the extension is free and complete on its own.
