Particle Flow
A live particle flow: smoky trails of thousands of particles run along a direction field, gathering into clouds and dispersing. GPU-rendered, zero dependencies. For AI products, data, science and anything that needs motion without noise.
React + Tailwind, shadcn-compatible: press “Copy for AI” and your Cursor or Claude Code agent installs it with the shadcn CLI.
What you can change
- speed — still, calm or lively; still draws a single frame with no loop
- intensity — faint, soft or bright: the accent strength; soft by default so the background does not fight the content
- density — sparse (700) or dense (1600): the particle count and frame cost
Built from
The install command brings these components too. The block only passes them props: their palette and behaviour stay their own.

Use it with AI
- 1. Copy the link.
- 2. Write to your agent in your own words and drop the link into the sentence.
- 3. The agent opens the link and installs the component from the registry.

FAQ
- How do I add Particle Flow with Cursor or Claude Code?
- Press “Copy for AI” on this page and paste it into your agent's chat. The instruction contains the shadcn CLI install command, the dependencies and what to keep, so the agent installs this exact component instead of recreating a lookalike.
- What does Particle Flow depend on?
- No npm packages beyond React and Tailwind CSS. It also installs catalog components: mockup-010.
- What can I change in Particle Flow?
- Adapt: speed — still, calm or lively; still draws a single frame with no loop; intensity — faint, soft or bright: the accent strength; soft by default so the background does not fight the content; density — sparse (700) or dense (1600): the particle count and frame cost. Keep as installed: the mockup-010 imports from @/components/vibeui/ — do not inline their code into the block or swap in your own; the parts receive props only; the local --vibeui-surface-013-* palette — do not swap it for your theme tokens; the canvas resolution chosen for this effect — higher is invisible to the eye, lower breaks the picture.
- Is Particle Flow free?
- Yes. The preview is open without an account; with a free account you can copy up to 20 components a month.
For developers
npx shadcn@latest add https://vibeui.club/r/pro/surface-013.jsonThis command needs a signed link: sign in and open “Component source” below — it issues a working link valid for 30 minutes. All install options
Technical notes
A composite block: imports mockup-010 from @/components/vibeui/ — the install command brings them along with the block. The block owns the layout and its own text, passes the parts props only and leaves their --vibeui-<name>-* palettes alone. One file, zero npm dependencies, "use client", canvas2D without WebGL. Up to 1600 particles in flat Float32Arrays follow a direction field from simplex noise (a table-free JS implementation); the frame is not cleared but dimmed with a translucent fill of the base color — trails fade on their own. The palette is CSS variables with light-dark read through the canvas computed border-color. DPR ≤ 1.5 for thin lines. Paused outside the viewport and in a hidden tab, prefers-reduced-motion and speed=still draw a single pre-warmed frame (40 steps), a radial-gradient fallback until the first frame. Palette --vibeui-surface-013-*.
