Facebook outperforms Arc XP in 6 of 7 categories, with a stronger composite score (72 vs 70). Arc XP leads in no categories.
Arc XP 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 performance. Its audit data shows consistent strength in these areas across the sampled sites.
Scores are medians across 29 audited Arc XP sites and 1367 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.
