What is GSAP?

GSAP is a high performance animation library. Designers use it for smooth scroll and motion effects.

In the tech stack detector, GSAP shows up in the JavaScript group. Knowing a site runs GSAP tells you how it is built and what it is set up to do.

How to detect GSAP

Look for gsap.min.js or the greensock CDN in the page scripts.

You do not have to dig through page source by hand. Paste the website into the detector above and it reports GSAP along with the CMS, analytics, pixels, hosting, payments, chat, email, and CRM the site uses.

Why it matters for agencies

Knowing a prospect runs GSAP (or does not) shapes your pitch. The detector also flags the gaps: if a site has no CRM, no chat widget, no review tool, or no ad pixel, that is a clear opening for a GoHighLevel CRM, an AI chat or voice agent, review automation, or a paid ads setup.
