ARIA DevTools
What ARIA DevTools is
ARIA DevTools is a free browser extension for reviewing accessibility signals in web applications. It helps identify missing ARIA labels, incorrectly used ARIA roles, and incomplete keyboard support. Its screen reader view presents page elements according to their explicit or implied ARIA roles, including headings, images, tables, and form items. After installing the extension, users open a website and click the browser extension icon. The maker says the extension is available for Chrome and Firefox. The project is open source under the MIT license. The Chrome Web Store places it in the Developer Tools category and reports 10,000 users; that listing also says the developer disclosed that user data will not be collected or used. GitHub is the support destination for questions, suggestions, and problems, and the project welcomes pull requests and raised issues. The maker says further work depends on finding a project sponsor. The Free plan is listed as free, and there is no separate free trial.
