  description

  Is your website accessible to everyone? Many businesses face legal risks and lose customers due to accessibility barriers they don't even know about. AccessCheck scans any web page and instantly identifies accessibility issues — then explains each one in plain English with step-by-step fix instructions. No WCAG expertise required.
  
  AccessCheck runs 50+ automated accessibility checks powered by axe-core, the global standard for accessibility testing. It evaluates your web page against WCAG 2.1 and WCAG 2.2 guidelines and presents results in a friendly side panel with an A-to-F letter grade.
