Ace by DAISY is accessibility checking software for EPUB publications.
It’s designed to help publishers, production teams, vendors, and authors evaluate EPUB files against accessibility expectations before release. The software is most useful as part of a broader quality assurance process, flagging issues that need review while recognising that automated testing can’t replace human accessibility assessment.
This is free and open source software.
