FlippingBook outperforms Cart Functionality in 7 of 7 categories, with a stronger composite score (78 vs 73). Cart Functionality leads in no categories.
Cart Functionality doesn't clearly lead FlippingBook in any category on the sampled sites — pick it based on developer experience, ecosystem, or existing team skills rather than the audit scores.
Choose FlippingBook when your primary concern is server response time and best practices. Its audit data shows consistent strength in these areas across the sampled sites.
Scores are medians across 554 audited Cart Functionality sites and 3 audited FlippingBook 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.

Small sample: one or both technologies have fewer than 10 audited sites. Treat these numbers as directional — medians stabilize around 20–30 audits per side.
