Sentry is an application monitoring platform that captures JavaScript errors, backend exceptions, performance traces, and crash reports from your running application. StoreVitals scans ecommerce stores for SEO issues, broken links, accessibility failures, and security misconfigurations. They address different problems.
Sentry and StoreVitals monitor different layers of your store's health. Sentry watches what happens inside your application while it runs — errors thrown by JavaScript, exceptions from your backend, performance bottlenecks in your code. StoreVitals audits what your store looks like from the outside — how Googlebot sees it, whether all links work, whether accessibility requirements are met, whether security headers are set. A production ecommerce store benefits from both: Sentry to catch the checkout button that silently broke in last week's deploy, and StoreVitals to catch the canonical tag misconfiguration that's been splitting your SEO authority for two months. Neither replaces the other.
