Facebook outperforms Backbone.js in 6 of 7 categories, with a stronger composite score (72 vs 72). Backbone.js leads in no categories.
Backbone.js doesn't clearly lead Facebook in any category on the sampled sites — pick it based on developer experience, ecosystem, or existing team skills rather than the audit scores.
Choose Facebook when your primary concern is server response time and accessibility. Its audit data shows consistent strength in these areas across the sampled sites.
Scores are medians across 61 audited Backbone.js sites and 1407 audited Facebook 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.
