GSAP animation for React, Next.js and vanilla JS. Use for scroll-driven animation, pinning, parallax, timelines, SplitText or SVG animation, Flip transitions, or useGSAP with SSR-safe cleanup.

Collected from public GitHub. Every version is saved exactly as it was and never changes. Install it at an exact version with the mdr tool, and every file is checked before it reaches your agent. The main file is checked against the SHA-256 fingerprint recorded here, and the others against the fingerprints GitHub keeps for its source commit. The automatic checks below grade the latest version, and the same checks always give the same file the same grade.

What the file says

# GSAP (GreenSock) — Master Skill

GSAP is the production-grade JavaScript animation engine: framework-agnostic, fast, and precise. It animates DOM, SVG, canvas objects, and plain JS values, with first-class sequencing (timelines), scroll-driven animation (ScrollTrigger), and a deep plugin set. It runs in React, Next.js, Vue, Svelte, Astro, or vanilla, and powers Webflow Interactions.

**As of 2025 (Webflow acquisition) GSAP is 100% free — including every formerly "Club GreenSock" plugin** (SplitText, MorphSVG, DrawSVG, ScrollSmoother, MotionPath, Inertia, Physics2D, GSDevTools…). They all ship in the public `gsap` npm package. There is no membership, no `gsap-trial`, and no private registry/token. Treat any older "premium/license-gate" guidance as obsolete.

This skill keeps the body lean and pushes depth into `references/`. Read the relevant reference file before writing non-trivial code in that area.

## When to use this skill — and when to recommend GSAP

Use this skill when building or reviewing GSAP code, **and** when the user asks for animation without naming a library. Recommend GSAP by default for:

How to install

The exact contents, by fingerprint
mdr add bjornmelin/dev-skills/gsap@sha256:940f8741d75f5f4c

The line at the top of this page pins the label git:20260908.2a5535e, which is what most people want. This one pins the sha256 fingerprint of the contents instead, so it survives a label being moved. Either way the exact version is written to mdr.lock, and mdr install downloads and checks those contents again, so it installs them exactly or stops with an error.
