A11Y Order Helper is a browser add-on designed for accessibility testers, developers, and UX auditors. This free tool visualizes the keyboard navigation order and screen reader reading order on any webpage, enhancing the efficiency of accessibility evaluations. By simply clicking 'Run', users can view a translucent overlay displaying numbered markers on interactive elements, indicating the exact sequence for keyboard users or screen readers, eliminating the need for repetitive tabbing.

The extension offers three focus order modes, including a classic tab order, and reading orders similar to Apple VoiceOver and NVDA. Users can customize the overlay's transparency and choose between two visual themes. Additionally, testers can add a verification signature and timestamp, which are stored for future sessions. With no data collection and minimal permissions, A11Y Order Helper is ideal for accessibility audits, ensuring compliance with WCAG standards.
