GSAP + ScrollTrigger vs WebGL
GSAP + ScrollTrigger and WebGL solve the same job (Animation & motion), so this is a pick-one decision. GSAP + ScrollTrigger is our default here: This is the scrolled-feature-article tool. Pinned photo sequences, a headline that assembles as you scroll, a timeline piece that scrubs — that is ScrollTrigger, and nothing else comes close. Webflow acquired GreenSock and made every formerly-paid plugin free in 2025. Core + ScrollTrigger + SplitText is ~49 kB gz. Watch out: Free but not OSI open source — a custom Webflow-owned licence that bars using GSAP inside competing no-code animation builders. Building scroll-driven features with it is squarely permitted. Release cadence has slowed to 2–3/year under Webflow.
- Editor's pick: GSAP + ScrollTrigger.

| What it is | Framework-agnostic animation engine whose differentiator is the timeline model: sequence, offset, nest, reverse and scrub complex choreography with precise control. ScrollTrigger handles scroll-driven and pinned animation; SplitText does per-character reveals. | The native JavaScript API underneath everything above: GPU-accelerated rendering in a canvas, programmed with GLSL shaders and manual buffer management. Zero bundle cost, nothing to install. |

| Why builders pick it | This is the scrolled-feature-article tool. Pinned photo sequences, a headline that assembles as you scroll, a timeline piece that scrubs — that is ScrollTrigger, and nothing else comes close. Webflow acquired GreenSock and made every formerly-paid plugin free in 2025. Core + ScrollTrigger + SplitText is ~49 kB gz. | Worth knowing as a term, not as a thing you write. A spinning cube is ~300 lines of raw WebGL versus ~20 of Three.js. Reach for it only when you need a custom shader no library exposes. |
| Watch out for | Free but not OSI open source — a custom Webflow-owned licence that bars using GSAP inside competing no-code animation builders. Building scroll-driven features with it is squarely permitted. Release cadence has slowed to 2–3/year under Webflow. | Each live WebGL canvas holds GPU memory, browsers cap concurrent contexts around 8–16, and an always-running rAF loop drains laptop batteries and pins mid-range Android. |
