HSTS outperforms Bootstrap in 6 of 7 categories, with a stronger composite score (75 vs 73). Bootstrap leads in no categories.
Bootstrap 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.
Choose HSTS when your primary concern is server response time and security. Its audit data shows consistent strength in these areas across the sampled sites.
Scores are medians across 874 audited Bootstrap sites and 2487 audited HSTS 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.
