HSTS outperforms ZURB Foundation in 7 of 7 categories, with a stronger composite score (75 vs 72). ZURB Foundation leads in no categories.
Choose HSTS when your primary concern is server response time and performance. Its audit data shows consistent strength in these areas across the sampled sites.
ZURB Foundation doesn't clearly lead HSTS in any category on the sampled sites — pick it based on developer experience, ecosystem, or existing team skills rather than the audit scores.
Scores are medians across 2488 audited HSTS sites and 93 audited ZURB Foundation sites in the BeaverCheck database. 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.
