Editoria11y Accessibility Checker – WordPress plugin (opens in new tab)

Editoria11y (“editorial accessibility ally”) is a quality assurance tool built for an author’s workflow. This plugin is the WordPress adaptation of the open-source Editoria11y library. Tests run in the browser and findings are stored in your own database; nothing is sent to any third party. It is meant to supplement, not replace, testing your code and visual design with developer-focused tools and testing practices.
