REAL

Holds up: a scroll-driven burger concept site built with GSAP and Three.js is a real portfolio piece on real, free tools, sold as a studio showreel rather than a product

Facebook · Oct 2026

The claim'GSAP + Three.js website made me hungry.' 'Stacked' is a concept site built to feel like pure appetite: sizzling meat, melting cheese, each layer stacking as you scroll, ending on a finished burger and an 'Order the burger' button. 'Every detail is designed to pull you in.' Hashtags: #webdesign #coding.

This one is what it says it is. The reel is a screen recording of a scroll-driven concept page named Stacked: a patty on a grill, close-ups of char and cheese, bun and layers assembling as the viewer scrolls, a finished burger, then a dark nav with Menu, Craft, Locations, Order and an 'Order the burger' button. The two tools named in the overlay are real and free. GSAP, the animation library, has been '100% free for all users' since Webflow took it over, including the plugins that used to cost money, and Three.js is an MIT-licensed JavaScript 3D library with about 116,000 GitHub stars. Scroll-triggered sequences like this are the standard GSAP ScrollTrigger pattern, and Three.js handles any 3D or WebGL layer. The caption is honest that it is a concept site, not a client's live restaurant, and there is no comment-for-link hook, no course and no affiliate code; the only sell is implied, which is 'hire the studio that made this'. Two caveats keep this at Medium confidence: no live URL is shown, so the build cannot be inspected, and the food imagery looks like rendered or generated frames rather than a photographed product, which is fine for a concept but would be a different conversation for a real restaurant's menu. Heavy WebGL hero pages also carry a mobile performance cost the reel does not show.

What holds up

Reel read frame by frame: overlay 'GSAP + Three.js, website made me hungry', a laptop screen scrolling a page titled Stacked with sections 'Built to break your self control', 'Charred at the edges, perfect in the center', 'Layer by layer, bite by bite', 'Every detail designed to torture your appetite', 'Finished to perfection', then nav (Menu, Craft, Locations, Order) and an 'Order the burger' button.
gsap.com/pricing: 'GSAP is now 100% free for all users, thanks to Webflow's support', maintained by the original team at Webflow; formerly paid plugins are included.
github.com/mrdoob/three.js: 'JavaScript 3D library', MIT license, about 116.2k stars at check time.
Caption states it is a concept site; no live URL, client, course, community or comment hook is offered. The implied sell is the studio's own services.

What doesn’t

Concept site, not a live restaurant: no URL to test speed, mobile behavior or the order flow.
Food frames look rendered or generated; a real restaurant would need its own photography to avoid showing a burger it does not serve.
Scroll-heavy WebGL pages are showreels first; on a phone with a weak connection they can be slow, which matters for an actual ordering site.

The catch

It is a real build on real free tools, and a good one, but it is a showreel. The hard part of a restaurant site is the menu, the hours, the ordering link and a page that loads fast on a phone in the parking lot, and none of that is what this reel is selling.

How to actually do it

If you want this effect on your own site, GSAP with ScrollTrigger is free; start from the official scroll-sequence demos and swap in your own product shots.
Shoot the actual product. Renders and generated food sell the designer, not the restaurant; customers notice when the burger on the site is not the burger in the bag.
Keep the cinematic hero to one section and make sure menu, hours, location and order button load first on mobile; test on a real phone before you ship.

GSAP and Three.js are real, free and suited to exactly this kind of scroll animation, and the caption is honest that Stacked is a concept. The only thing to watch is that a showreel page is not a working restaurant site, and the imagery is not a real menu.
