Support Every Aspect of Accessibility with Open Source
We’ve assembled a list of tools that can help you at every stage of your accessibility journey. These tools and learning resources are free (free as in free speech) and open for anyone to use and update. If you have any questions or other tools we should watch, feel free to contact me on Twitter (@bbertucc) or via email (firstname.lastname@example.org).
axe-core: One of the most accurate automated scanning solutions. (Remember that automated tests only detect a small amount of accessibility errors!)
pa11y: CLI-focused automated testing. Note: The project development has slowed and I highly encourage devs to fork and use.
npm alt-text: Check for unhelpful alt-text via this npm Node module.
Maintain accessibility from a single WordPress Install using the following tools:
WP Accessibility: This fixes many known accessibility issues with WordPress. Every WP installation should include this plugin! It is maintained by the leading accessibility practitioner in the WordPress community.
Editora11y Plugin: Like an accessibility spell checker. See accessibility errors as you develop your content.
Equalize Accessibility Checker: This plugin includes many automated accessibility tests you can perform on your WordPress site. (Note: Automated tests won’t detect all accessibility errors.)
Editora11y Module: Like the WordPress plugin, but built to find accessibility errors with CKEditor.
Accessibility Scanner: Sitewide accessibility scanner using the axe-core automated testing system. (Note: Automated tests won’t detect all accessibility errors.)
