Developed by researchers at the University of Lisbon, it analyzes HTML and CSS to detect violations of the Web Content Accessibility Guidelines (WCAG). The platform provides automated assessments of various accessibility barriers, offering detailed reports that help developers identify and fix structural issues. It is intended for web developers, content creators, and quality assurance teams.

help QualWeb FAQ

What accessibility standards does QualWeb test?

QualWeb automatically checks webpages against selected WCAG 2.1 techniques and ACT Rules. It is intended to support accessibility evaluation, but automated results do not replace testing with people or manual review.

Who developed QualWeb?

QualWeb was developed by accessibility researchers associated with the University of Lisbon and its LASIGE research community. The project is presented as an open-source web accessibility evaluation engine.

Can QualWeb analyze JavaScript websites?

QualWeb is designed for automated webpage evaluation and can work with rendered web content, including pages that depend on JavaScript. Its results focus on detectable rules and should be reviewed alongside manual keyboard and assistive-technology testing.

Is QualWeb a replacement for an accessibility audit?

No. QualWeb can find many machine-testable issues in HTML and rendered pages, but it cannot judge every usability problem. A complete WCAG review also needs manual checks, including keyboard operation, focus behavior, labels, and meaningful alternative text.
