DefectLab: accessibility bugs with measuring tape

Editorial interest 84/100 Selection signal · not a rating of the site

A collection of deliberately broken, static websites for testing accessibility scanners against known defects.

Landing page captured for the 2026-08-28 issue.

Field notes

The project separates scanner evaluation into individual and consolidated test conditions. Its mirrored UK GDS material offers 138 pages and 142 defects in one format, or 132 defects on a single page, while the authored WCAG 2.2 suite covers Level A and AA criteria across 19 static HTML pages. Cases are marked in the markup, and each defect has a correct twin to help distinguish real findings from false positives.
