How do you monitor WCAG compliance on a headless Shopify store?

Tie accessibility checks to deployments and monitor the rendered customer experience, not just source components. Crawl production routes, exercise menus, product options, dialogs, cart, forms, and errors in a real browser, and add manual keyboard and screen reader checks to critical flows. Diff new failures against the last clean build and keep verification evidence after repairs.

Test the complete stack

Headless storefronts combine framework code, a design system, APIs, third-party scripts, and Shopify commerce state. Unit tests for individual components do not prove the integrated flow works after hydration and data loading.

Use release-aware evidence

Store the commit or release identifier with each scan, page, selector, criterion, and result. When a regression appears, teams can identify the responsible release, repair it quickly, and show when production returned to a passing state.
