Field notes
AdaScan frames accessibility monitoring as an alternative to runtime overlays: submit a URL, receive a ranked set of WCAG findings, and pass the suggested fixes to a developer. Its own qualification is important: automated checks cover only about 30–40% of WCAG, so human review remains necessary. The page also describes a dated history of scans and fixes, while pricing and the depth of ongoing monitoring are not shown.
