How this comparison was built

Scores are medians across 875 audited Bootstrap sites and 94 audited Slick 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.
