Engineered for performance

Every API designed to be intuitive. Every animation buttery at 120fps.

WebGPU Renderer

Native GPU acceleration for every animation. Complex particle systems, 3D transforms, and shader effects.

renderer: 'webgpu'

particles: 50_000

fps: 119.7 // stable

Live Code

Write it, see it. Hot module replacement with instant preview.

scene.add('particle-field')
scene.play({ loop: true })

// Output:

50,000 particles

120fps locked

Smart Stagger

Orchestrate complex sequences with one line. Elements animate in spatial order.

Scroll Observer

Pin, scrub, and trigger with scroll progress. Built-in viewport detection.

One-Click Deploy

Push to production in seconds. Automatic CDN distribution and bundle optimization.

"I prototyped a scroll-driven 3D product showcase in 45 minutes. With raw GSAP it was taking me a full day. The stagger API alone saved me from writing 200+ lines of sequencing logic."
