When to choose Sentry

Choose Sentry when your primary concern is server response time and best practices. Its audit data shows consistent strength in these areas across the sampled sites.

Every audit runs the same 100+ checks — Lighthouse performance, security headers, accessibility, SEO, server response time — against a real URL. No vendor input, no sponsorship, no affiliate links.
