About SKMDemo

SKMDemo is a collection of interactive HTML demos: animations, simulators and explainers built with canvas, SVG, CSS, WebGL and plain JavaScript. Each demo is a single self-contained page that opens full screen, works on phones and desktops, and follows your light or dark theme.

How it works

Every demo is one HTML file with no outside assets and no sign-up. Before a demo is published it is checked against a written content standard covering its title and description, accessibility, reduced-motion support, responsive layout and file size, so what you open is predictable.

Finding demos

Use the search box on the home page, filter by tag, or browse all tags. Every demo has its own address you can share.

Who makes it

SKMDemo is made and curated by SKM. The source code for the site is on GitHub.
