What A11y Check is
A11y Check is a web accessibility auditing service that samples representative pages from a site and checks them against WCAG 2.2 and KWCAG 2.2. It describes 113 automated rules mapped to 30 of WCAG 2.2’s 55 A/AA success criteria. Reports provide findings, code locations, remediation guides, a checkpoint matrix, and PDF export; free accounts also have CSV export. The workflow identifies checks that need human judgment and supplies instructions for carrying them out. A browser extension and API are listed, and the @a11ychk/mcp server integrates with Claude Code and Cursor to scan localhost pages and provide remediation guidance. A no-login check covers one page and is limited to twice daily; results are not saved. A free account adds site-wide scans, a KWCAG matrix, manual review workflow, and report exports. The service cautions that automated checks identify only part of accessibility issues and cannot establish conformance on their own. PDF export is print-optimized and does not support tagged PDF (PDF/UA). A11y Check is built and run by the web manager at Daegu Cyber University.
