RSS outperforms Lightbox in 6 of 7 categories, with a stronger composite score (75 vs 73). Lightbox leads in no categories.
Lightbox doesn't clearly lead RSS in any category on the sampled sites — pick it based on developer experience, ecosystem, or existing team skills rather than the audit scores.
Choose RSS 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 52 audited Lightbox sites and 886 audited RSS 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.
