help WebAIM WAVE FAQ
Is WebAIM WAVE free to use?
Yes, the core WAVE (Web Accessibility Evaluation Tool) is completely free to use on the official WAVE website. There are also free browser extensions available for Chrome, Firefox, and Microsoft Edge.
What does the WAVE accessibility tool check for?
WAVE evaluates web pages for compliance with various WCAG (Web Content Accessibility Guidelines) criteria. It visually highlights structural and semantic HTML issues, color contrast errors, missing alternative text for images, and improper ARIA usage.
How do I use WAVE on a local development environment?
Because WAVE is a web-based tool, it cannot scan websites protected behind a firewall or local development servers. To test these sites, developers must use the WAVE browser extension, which can evaluate locally hosted URLs and password-protected pages directly within the browser.
Who develops the WAVE accessibility checker?
WAVE is developed and maintained by WebAIM (Web Accessibility In Mind), a non-profit organization based at Utah State University. WebAIM has been a leading advocate for digital accessibility since its founding in 1999.
