Ace by DAISY – accessibility checking software for EPUB publications

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.

• Checks EPUB publications for automated accessibility issues.
• Assists with evaluation against the EPUB Accessibility Specification.
• Runs as a command line tool, JavaScript Node module, or through an HTTP API.
• Generates HTML reports covering violations, metadata, document outlines, and images.
• Offers an official desktop app for Linux, macOS, and Windows.
