TheWCAG Accessibility Visualizer

Web accessibility visualizer browser extension

TheWCAG Accessibility Visualizer has a single, narrow purpose: to display web accessibility information as visual overlays on web pages. The extension visualizes accessibility-related data (such as ARIA attributes, heading levels, form labels, and image alternative text) that is normally invisible to sighted users but is critical for assistive technologies. This helps developers, designers, and accessibility professionals understand how web content is perceived by screen readers and other assistive technologies, enabling them to identify and fix accessibility issues more efficiently. The extension does not modify web page content, track user behavior, collect personal data, or perform any function beyond displaying accessibility information overlays.
