Bootstrap outperforms Skrollr in 6 of 7 categories, with a stronger composite score (75 vs 74). Skrollr leads in no categories.
Choose Bootstrap when your primary concern is server response time and performance. Its audit data shows consistent strength in these areas across the sampled sites.
Skrollr doesn't clearly lead Bootstrap 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 1117 audited Bootstrap sites and 11 audited Skrollr 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.
