Google Font API doesn't clearly lead parallax.js in any category on the sampled sites — pick it based on developer experience, ecosystem, or existing team skills rather than the audit scores.
Choose parallax.js 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 1019 audited Google Font API sites and 21 audited parallax.js 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.
