About Number Pop
Number Pop animates only the digits that changed, popping each from a blur one after another, so 65.78 to 65.92 moves two characters.
Number Pop is an UI transition 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 Number Pop
- Prices and totals.
- Live stats.
- Crypto and stock tickers.
- Scoreboards.
How it works
Digits are compared by position and changed ones re-enter with a stagger.
The change it animates is also announced to assistive tech, and the motion is short enough never to block what the user wants to do. With prefers-reduced-motion on, it holds still or settles instantly instead of animating.
Customizing Number Pop
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 stagger live, and the Code tab updates to match, so the snippet you copy already carries your values.
- value (number).
- format ((n: number) => string): For currency, percentages and so on.
