Facebook outperforms MobX in 7 of 7 categories, with a stronger composite score (72 vs 71). MobX leads in no categories.
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.
MobX 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.
Scores are medians across 1407 audited Facebook sites and 69 audited MobX 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.
