HSTS outperforms GSAP in 3 of 7 categories, with a stronger composite score (75 vs 73). GSAP leads in no categories.
GSAP 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 performance and security. Its audit data shows consistent strength in these areas across the sampled sites.
Scores are medians across 238 audited GSAP sites and 2488 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.
