Three.js Snippets — Free HTML CSS JS Three.js WebGL Scenes & Shader Effects

Yes, though they are the heaviest snippets in the library. Each one clamps devicePixelRatio and resizes with the viewport, which is what keeps a retina phone from rendering four times the pixels it needs. For low-end devices, reduce the particle count or geometry detail first — that is almost always the bottleneck, not the shader.

Keep the id returned by requestAnimationFrame and call cancelAnimationFrame on teardown, then dispose the geometry, materials and renderer. The framework exports do this in the cleanup function; if you paste the raw JS into a single-page app, add it yourself or the loop keeps running against a detached canvas.

Yes — add GLTFLoader from the same CDN, load your .glb, and add the returned scene to the existing scene graph. The camera, lighting and resize handling in these snippets stay exactly as they are.

No. Every snippet is plain HTML, CSS and vanilla JavaScript that runs in any page — a static file, a WordPress theme, a Rails view, anything. When you do want a framework version, the editor exports each snippet as a React component, a React + Tailwind component, a standalone Tailwind HTML file, a Vue 3 single-file component or an Angular standalone component.

Yes — copy, modify and ship them in personal or commercial work, with no attribution required and no licence to track.

Yes. Every snippet opens in a live editor with separate HTML, CSS and JS panels and a preview that updates as you type. Check it at mobile, tablet and desktop widths, then copy the code or export it in your framework of choice.
