When to choose core-js

core-js doesn't clearly lead GSAP in any category on the sampled sites — pick it based on developer experience, ecosystem, or existing team skills rather than the audit scores.

When to choose GSAP

Choose GSAP when your primary concern is server response time and best practices. Its audit data shows consistent strength in these areas across the sampled sites.

How this comparison was built

Scores are medians across 1650 audited core-js sites and 261 audited GSAP 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.
