React outperforms Zepto in 7 of 7 categories, with a stronger composite score (76 vs 72). Zepto leads in no categories.
Choose React when your primary concern is server response time and accessibility. Its audit data shows consistent strength in these areas across the sampled sites.
Zepto doesn't clearly lead React 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 1230 audited React sites and 17 audited Zepto 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.
