Vially Inspector is a Chrome DevTools extension designed to facilitate accessibility automation testing for web developers and testers. This free tool enables users to inspect web pages for common accessibility issues, ensuring that websites are usable by everyone. Key features include checking color contrast, heading structure, focus order, and readable language levels, as well as simulating various visual impairments and reading difficulties.

By integrating accessibility checks directly into the DevTools environment, Vially Inspector streamlines the process of identifying and addressing potential accessibility barriers. It assists users in understanding how different audiences may experience a webpage, ultimately guiding them to make informed improvements before the final release. This makes it an invaluable resource for anyone involved in web development or quality assurance.
