Apple outperforms CartStack in 6 of 7 categories, with a stronger composite score (73 vs 74). CartStack leads in composite score.
Choose Apple when your primary concern is accessibility and best practices. Its audit data shows consistent strength in these areas across the sampled sites.
CartStack doesn't clearly lead Apple 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 1275 audited Apple sites and 1 audited CartStack 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.
