GSAP Timeline — Sequenced Animation Foundation

Q: Why pick this technology over alternatives?

It has the largest production-quality ecosystem, the most documentation, and the most experienced developers available. For a site you want to maintain for 3+ years, ecosystem maturity matters more than feature peak.

Q: What if a newer tool comes out next year?

I track new tooling and migrate when it makes sense, but only after the new tool ships stable production releases for at least 6-9 months. I don't rebuild client sites on bleeding-edge tools — that's the path to broken sites.

Q: How long does this take?

Standard scope: 4-6 weeks from contract signature to live site. Larger scope (configurator, multi-scene scrollytelling) takes 8-12 weeks. Rush projects (2-3 weeks) are accepted with a 30-40% rush surcharge.

Q: What does it cost?

Hero-section 3D upgrade: \$1,500-\$2,500. Full multi-scene 3D site: \$3,500-\$8,000. Configurator with custom shaders: \$5,000-\$12,000. All fixed-price, source code included. EUR equivalents on request.

Q: What if my visitors are on weak phones?

The site detects device tier before the first scene loads and serves a lighter version on weak hardware (fewer particles, simpler shaders). Devices without WebGL get a static fallback that preserves the visual language and conversion path.

GSAP Timeline lets you sequence and synchronize multiple animations on one shared time axis — the backbone of polished motion.

GSAP Timeline is the construct that makes complex motion manageable. Instead of nested setTimeouts or Promise chains, you build a timeline, add tweens with positional offsets ("+=0.3" or "<0.5"), and the whole sequence plays as a unit. Timelines can be paused, reversed, scrubbed, and nested inside other timelines. For scroll-driven sites, the master timeline is scrubbed by ScrollTrigger. For event-driven motion (button clicks, hover states), you call timeline.play(). One timeline, many entry points.

Performance budget

Lighthouse mobile target: 85+ across all categories. I measure on real devices, not just emulator. Asset compression: glTF + Draco for meshes, KTX2 for textures, Brotli for shaders. Lazy-load any gsap timeline scene that isn't above the fold so the first paint stays under 1.5s.

When this is overkill

If the goal is a simple e-commerce listing or content blog, a full gsap timeline setup is overkill — a CSS-driven hero plus static images converts just as well at 1/10 the cost. gsap timeline earns its keep when the brand needs a memorable visual moment or when 3D actually clarifies the product (configurators, tours, demos).

What you get hands-off

After delivery: source repository on GitHub (private), commented code, a 5-min Loom walkthrough explaining the scene logic, and the asset pipeline documented. First year of hosting and minor revisions is included. After that we agree on a maintenance plan if needed.

What this delivers

Concrete output: a working gsap timeline integration on a real production site, not a demo. The integration includes device-tier detection so weak phones get a lighter version automatically. Source files are handed over in their original formats — Blender, GLSL, glTF — so any future developer can continue where I stopped.
