WAVE is WebAIM's free in-browser accessibility evaluation tool — visual overlays show errors directly on the rendered page. StoreVitals monitors accessibility continuously across your full catalog alongside SEO, security, and performance.
WAVE is the gold-standard one-page evaluator with the best in-page visual experience for understanding what's wrong on a single URL — front-end engineers should keep the extension installed for development. StoreVitals is the right tool for continuous production monitoring across an ecommerce catalog: dozens or hundreds of product pages get audited weekly, regressions trigger alerts, and accessibility shows up next to SEO and security in a unified health score. The pattern that works: WAVE during development for visual debugging, StoreVitals in production for catalog-wide coverage and alerting. Most ecommerce teams need both — they're not duplicates, they're different lifecycle stages of the same accessibility commitment.
