What is aCe

aCe is the W3C-recognised accessibility validator from AccessiWay with which you can obtain the accessibility score of a web page. Using this tool, it is possible to create reports containing – in addition to the website accessibility assessment – specific information on detected errors and advice on how to adapt them in order to make the website accessible and compliant.

How does it work?

aCe uses AI and an automated process to scan your website, detecting accessibility errors to give you a clear idea of your compliance.
