Vially Inspector

Vially Inspector is a DevTools extension for accessibility testing. It helps developers, designers, QA testers, and accessibility reviewers inspect the currently open webpage for common accessibility issues directly inside DevTools. Users can check colour contrast, heading structure, focus order, readable language level, screen reader structure, and visual accessibility simulations such as colour vision deficiency, vision impairment, reading difficulty, and page dark mode. Users should install Vially Inspector if they want a practical way to review accessibility while building or testing websites. The extension keeps accessibility checks close to the page being inspected, making it easier to find issues, understand how different users may experience the page, and make improvements before release.
