Hire a GSAP Developer: What to Look For in 2026

Since Webflow made GSAP 100% free in April 2025 — core, ScrollTrigger, SplitText, MorphSVG, the whole former Club GreenSock set — every front-end developer on Upwork suddenly lists it. That makes it harder, not easier, to hire a GSAP developer: the library is now a checkbox on 50,000 profiles, and importing gsap is not the skill you are paying for. The skill is choreography, and a frame budget that holds on a mid-range Android.

I have shipped GSAP-driven sites that were nominated for GSAP Site of the Year (Mat Voyce) and I sit on the Awwwards jury, so I have also reviewed hundreds of builds where the animation code was technically "GSAP" and the result still felt cheap. This guide is the vetting process I would use if I were on your side of the table: what a GSAP developer actually does, how to test a portfolio in ten minutes, the four questions that expose a pretender, and what it costs.

What a GSAP developer actually does (that a front-end dev doesn't)

Hiring people confuse two jobs:

• A front-end developer builds the design accurately, accessibly and fast. Animation is a garnish: fade-ins on scroll, a hover state, maybe a hero that slides up.
• A GSAP developer / motion engineer owns the feel. Sequencing, easing, pinned scroll narratives, page transitions that don't flash, text that splits and staggers on the right beat, and — crucially — all of it staying at 60fps while a WebGL canvas and a video are also running.

The tell is timelines. Amateur GSAP is a pile of independent tweens fired from scroll listeners. Professional GSAP is a small number of timelines whose progress is driven by something (scroll, drag, a state machine), so the whole page moves as one directed object:

// A directed hero: one timeline, scrubbed by scroll — not five disconnected tweens.
const tl = gsap.timeline({
  scrollTrigger: {
    trigger: sectionRef.current,
    start: 'top top',
    end: '+=140%',
    pin: true,
    scrub: 1, // smooths the link between scroll velocity and timeline progress
  },
});

tl.to(maskRef.current, { clipPath: 'inset(0% 0% 0% 0%)', ease: 'power2.inOut' })
  .from(splitRef.current.lines, { yPercent: 120, stagger: 0.06 }, '<0.2')
  .to(imageRef.current, { scale: 1.08, ease: 'none' }, 0);

If a candidate's code looks like the first pattern (tween soup), you are hiring someone who will produce motion that fights itself the moment the design changes.

The 10-minute portfolio test

Do this before any call. It filters ~80% of candidates.

1. Open their live sites on your own phone, on cellular. Not the showreel. Showreels are rendered at 60fps in After Effects; the web is not. Scroll fast, then scroll back up. Does anything stutter, tear, or jump?
2. Scroll to a pinned section and resize the window. Badly written ScrollTrigger pinning collapses on resize (content overlaps, the pin spacer is wrong). A pro calls ScrollTrigger.refresh() on the right events and uses gsap.matchMedia() for breakpoints.
3. Navigate away and come back. Client-side route changes are where GSAP work rots: leaked ScrollTriggers, doubled tweens, elements stuck at opacity: 0. If a hero is invisible after a back-navigation, the cleanup is broken. (This exact class of bug is why I wrote up why a WebGL hero disappears on browser back.)
4. Turn on Reduce Motion (iOS: Settings → Accessibility → Motion). A professional respects prefers-reduced-motion; the site should still work, just calmer. If nothing changes, they've never thought about it.
5. Check third-party validation. The GreenSock showcase, Awwwards, FWA, CSS Design Awards. These are juried by practitioners — much harder to fake than a testimonial.

The four questions that expose a pretender

In a 30-minute call, ask these. I'm giving you the answers a real GSAP developer gives.

1. "How do you clean up GSAP in React or Next.js?"

What you want to hear: useGSAP() from @gsap/react, with contextSafe for event-handler animations, so every tween and ScrollTrigger created in the scope is reverted automatically on unmount.

'use client';
import { useGSAP } from '@gsap/react';
import gsap from 'gsap';

export function Reveal({ children }: { children: React.ReactNode }) {
  const scope = useRef<HTMLDivElement>(null);

  // Everything created in here is auto-reverted when the component unmounts.
  const { contextSafe } = useGSAP(
    () => {
      gsap.from('[data-reveal]', { autoAlpha: 0, y: 24, stagger: 0.08 });
    },
    { scope }
  );

  const onEnter = contextSafe(() => gsap.to('[data-reveal]', { scale: 1.02 }));

  return <div ref={scope} onMouseEnter={onEnter}>{children}</div>;
}

Red flag: "I put gsap.to() in a useEffect." That works in a demo and leaks in production — every route change stacks another set of triggers.

2. "How do you make GSAP and smooth scroll share one clock?"

Anyone who has shipped a scroll-driven site with Lenis (or Locomotive) knows this is the #1 source of jitter: two RAF loops fighting. The correct answer is one loop — drive Lenis from GSAP's ticker (or a single external clock) and let ScrollTrigger update from Lenis' scroll event:

const lenis = new Lenis({ autoRaf: false });
lenis.on('scroll', ScrollTrigger.update);
gsap.ticker.add((time) => lenis.raf(time * 1000));
gsap.ticker.lagSmoothing(0);

If they shrug at this question, they have not built a premium scroll site. The long version is in my smooth scroll in Next.js with GSAP and Lenis guide — use it as an answer key.

3. "How do you hold 60fps with heavy motion on a mid-range Android?"

You want to hear: animate transform and opacity only (never top/left/width); promote layers deliberately, not everywhere; will-change used surgically; heavy assets lazily initialised; scrub instead of listening to scroll and animating manually; and an actual measurement habit — DevTools Performance panel, not vibes. Bonus points for capping device pixel ratio when a canvas is involved and for knowing that Core Web Vitals on animation-heavy sites is a design constraint, not a post-launch cleanup task.

4. "Show me something that broke, and how you fixed it."

Every senior practitioner has scars: a scroll-scrubbed video that stuttered on Safari, a SplitText instance that wasn't reverted and shredded the DOM on re-render, a pin that broke inside a position: sticky parent. War stories are the fastest proof of real hours. A candidate with only a flawless highlight reel has either not shipped much, or is not telling you the truth.

GSAP developer vs. animation library generalist

	Motion engineer (GSAP specialist)	General front-end dev	Template / no-code
Scroll choreography	Directed timelines, pin + scrub	Scroll-reveal fades	Preset effects
Text animation	SplitText, per-line masking, font-ready gating	CSS transitions	Not available
Perf under load	Budgeted, measured, 60fps on mid-range	Usually fine, untested under load	Varies wildly
WebGL interop	Shares one clock with the canvas	Rarely	No
Typical rate	$75–$150/hr	$40–$80/hr	—
Right for	Brand/launch/award-caliber sites	CRUD, dashboards, standard marketing	Tight budget, generic look

If you're still weighing tools rather than people, GSAP vs Framer Motion compares them honestly — short version: Framer Motion is excellent for component state and React micro-interactions; GSAP is what you use when the whole page is choreographed to scroll.

What a GSAP developer costs in 2026

Marketplaces will show you $25/hr GSAP profiles. What you get is the tween soup above — motion that works in the demo, breaks on the second route change, and drops frames on the devices most of your audience uses.

Independent senior motion engineers realistically run $75–$150/hr, and a defined scope is usually quoted per project rather than hourly. My own engagements sit at roughly $75–$100/hr effective, with focused project tiers from ~$1.5k–$3k+ and flagship, award-caliber builds above that. The full breakdown by scope is in how much an animated website costs.

The cost lever is not "how much GSAP" — it's how much choreography. A landing page with tasteful reveals is a fraction of the price of a pinned, scrubbed, WebGL-integrated narrative. Say which one you want and the number gets accurate fast.

Where GSAP developers actually hide

• Marketplaces (Upwork, Fiverr, Guru) — huge pools, almost no filtering on craft. Fine for small fixes; poor for flagship motion.
• Curated networks (Contra, YunoJuno, Toptal) — better vetting, still generalist; a "GSAP" tag rarely means award-level choreography.
• The GreenSock forums job board and showcase — where practitioners actually are.
• Awards sites (Awwwards, FWA, CSSDA) — reverse-engineer from work you admire: open the site's credits, find the developer. This is the highest-signal channel and almost nobody uses it.
• Design studios' white-label partners — many agencies subcontract exactly this skill, which is why I run a white-label creative development track for studios who need the motion layer they can't staff.

FAQ

Is GSAP still free for commercial use?

Yes. After Webflow acquired GreenSock, GSAP became 100% free — including the former paid Club plugins (ScrollTrigger, SplitText, MorphSVG, ScrollSmoother, DrawSVG, Inertia) — with the standard license covering commercial use. Budget for the developer, not the license.

How much does it cost to hire a GSAP developer?

Senior independents run $75–$150/hr; small defined scopes are typically quoted per project from around $1.5k–$3k+. Anything under ~$40/hr is a generalist who installed the library — you will pay the difference in rework.

What should I ask a GSAP developer in an interview?

Four questions cover it: how they clean up GSAP in React/Next.js (useGSAP + contextSafe), how they make GSAP and smooth scroll share one RAF loop, how they hold 60fps on a mid-range Android, and a real story of something that broke. Vague answers to the first two mean they haven't shipped a scroll-driven site.

Do I need GSAP, or is CSS/Framer Motion enough?

If your motion is component-level (hovers, modals, list transitions), Framer Motion or plain CSS is enough. If the page is the animation — pinned sections, scrubbed narratives, sequenced text, WebGL choreography — you want GSAP and someone who has directed it before. See GSAP vs Framer Motion.

Can a GSAP developer work with my existing agency or design team?

Yes — that's the most common shape. I frequently build the motion layer for design studios and brands while the studio keeps the client relationship and the art direction (recent example: the Mark Woodland build with a studio design team).
