Accessibility linting integrates automated accessibility rules into the development workflow itself, through editor plugins or build-time checks, so that a developer sees a warning about a missing label or invalid ARIA attribute while writing the code, rather than discovering it later in a separate audit after the feature has already shipped.
Catching issues this early is significantly cheaper to fix than remediating them after launch, and it steadily builds accessibility awareness into a development team’s everyday habits rather than treating it as a separate, occasional review step.
