About Laser Flow
Laser Flow sweeps a laser beam across a dark field from the top edge, bending toward the pointer, with bright packets flowing down it and a fog that catches the glow.
Laser Flow is an animated background for React 19, styled with Tailwind CSS 4 and animated with Motion. It drops into Next.js, Vite, Remix or Astro through the shadcn CLI as a single file you own.
When to use Laser Flow
- Tech and hardware launches.
- Gaming and esports.
- Nightlife and music.
- Bold call-to-action sections.
How it works
The beam is layered additive strokes with travelling radial packets. It runs on a canvas capped at 2x pixel density, pauses when scrolled off screen, and reads its colours from your theme tokens so it follows dark mode.
The whole layer is decorative and aria-hidden, sits behind your content without taking pointer events it does not need, and pauses when scrolled off screen. With prefers-reduced-motion on, it holds still or settles instantly instead of animating.
Customizing Laser Flow
Every prop is documented in the API reference above with its type and default. The ones you will reach for first are listed here.
The Customize panel next to the preview lets you change color, speed, width, intensity, fog live, and the Code tab updates to match, so the snippet you copy already carries your values.
- color (string, default "var(--ember)").
- speed (number, default 1).
- width (number, default 3): Beam core width in px.
- intensity (number, default 1).
- fog (boolean, default true).
