axe DevTools is a Chrome extension and CI integration for catching accessibility issues during development. StoreVitals continuously monitors production accessibility alongside SEO, security, and performance — they cover different points in the dev lifecycle.
Use both at different points in the lifecycle. axe DevTools is the right tool during development — every front-end engineer should have it installed, and CI integration prevents accessibility regressions from shipping in the first place. StoreVitals is the right tool for production monitoring after the fact: it catches regressions that slipped past local testing, surfaces accessibility alongside SEO and security, and alerts you when something breaks. Many ecommerce teams run axe in CI and StoreVitals in production. If you can only afford one and you're a small ecommerce team without a dedicated front-end engineer, StoreVitals will catch the highest-impact issues without requiring developer setup. If you have an engineering team shipping multiple deploys per week, axe in CI plus StoreVitals for production monitoring is the gold-standard pairing.
