Demos
Each demo is a real VectoUI app and a live stress test — dogfooding the engine right in your browser.
Stress test · Interaction · a11y
Danmaku at scale
Thousands of live comments on one canvas — each individually interactive and accessible, where DOM-based danmaku chokes past ~200.
Open demo →WebGPU · Compute · particlesNexus — a WebGPU particle field
Tens of thousands of particles simulated on a WebGPU compute pass — springing into the word “VectoUI”, flowing away from your cursor, with a transparent CPU fallback.
Open demo →Streaming · Markdown · a11yAI Chat — streaming Markdown
A chat client whose entire transcript is rendered on canvas: Markdown streams in token-by-token, with code, tables, images, and SVG-rendered math, Mermaid, and ABC notation. Plays prebaked answers with zero config, or point it at a local Ollama.
