Are the ai2 Progress toasters free?

Yes. The whole styled layer is free and MIT licensed, like the component core.

Can I change the size?

Yes. Every variation takes a size prop of sm, md, lg or xl, aligned to the base Button height scale.

Progress toasters

Five toast triggers that show how long is left before the toast dismisses itself: a bottom bar, a ring in the icon slot, a numeric countdown, a sweeping tint and a draining edge rule. The indicator is locked to one fixed timeout constant. Each is self-contained (no sonner package), sized and token-driven.

SonnerProgress

Installation

The styled layer is free and installs like any other ai2 component.

Run the following command

npx shadcn@latest add @ai2/sonner-progress

Dependencies, the @ai2/tokens theme and the component file are installed together.

Install dependencies

npm install motion lucide-react

/* Styled sonner - progress family: 5 self-contained toasters. NO sonner package and
   NO portal - each export renders a demo trigger button; clicking it pushes a toast
   onto a LOCAL stack (a useState array), and it appears in the bottom-right corner
   (fixed bottom-right, z-50). The difference: an indicator showing the time left
   until auto-dismiss (a bottom bar, a ring, a countdown, a sweep, an edge line). The
   duration is a FIXED constant (TOAST_MS) - the indicator is locked to it, making it
   deterministic (NO Date.now/Math.random).
   Under reduced-motion the indicator animation is skipped (it stays static) but the
   toast still auto-dismisses. Color comes ONLY from tokens, via alpha color-mix. */

Manual installs skip the @ai2/tokens theme, so add the token CSS from the theming guide or the tone colors will be missing.

Variations

5 takes on the same idea. Each is its own export, and every one accepts a size prop (sm, md, lg, xl) aligned to the base Button scale.

Bar

A progress bar along the bottom edge that drains to zero.

Ring

A circular ring in the icon slot that empties as time runs out.

Countdown

A numeric badge counting the remaining seconds.

Sweep

A tone-tinted layer that sweeps off the surface.

Edge

A vertical rule on the left edge that drains top to bottom.

ai2 Progress toasters: 5 styled variations on the token system

The ai2 Progress toasters are a set of 5 decorative button variations from the styled layer of the @ai2 design system, built around toast triggers with an auto-dismiss progress indicator. They are free and MIT licensed, and every color comes from a semantic token, so they theme with the rest of ai2 in light and dark.

Motion runs on framer-motion: framer-motion drains the bar, ring, sweep or edge across the fixed timeout. The styled layer is opt-in, so the dependency only lands if you use it; the base components stay lean. Under reduced motion, the indicator is drawn static and the toast still dismisses on time.

What is in the ai2 Progress toasters?

5 exports in one file: Bar, Ring, Countdown, Sweep and Edge. Each renders a native button and takes a size prop (sm, md, lg, xl) aligned to the base Button. They are separate from the base Button on purpose: the base keeps its clean variant, tone and size axes, while the styled layer carries the effects.

You own the file. Copy the one category file and you have all 5 variations, with no runtime dependency on ai2 itself.

Why use it

On-system by construction: Every color resolves to an ai2 semantic token, so the buttons follow your theme in light and dark with no extra work.
Effect without the sprawl: The decorations live in a dedicated styled file, so the base Button keeps its clean, predictable API.
Accessible and honest: Each renders a real button element, keeps a visible focus ring, and respects prefers-reduced-motion.

Features

Token-driven color: No hardcoded hex or oklch; the look recolors with your theme tokens.
framer-motion: framer-motion drains the bar, ring, sweep or edge across the fixed timeout.
Reduced-motion aware: Under prefers-reduced-motion, the indicator is drawn static and the toast still dismisses on time.
Size aligned to the base: Every variation takes sm, md, lg and xl matching the base Button height scale, so styled and base buttons line up in a row.

Production tips

Use it for emphasis, not everywhere: Styled buttons draw the eye. Reserve them for the one action you want people to take on a screen, and use the base Button for the rest.
Keep labels as verbs: The decoration adds weight, so a clear action label keeps the button scannable.
Pick one variation per surface: The variations share a family; using two different ones in the same view competes for attention.

Works with the rest of ai2

The Progress toasters sit alongside the base Button and the rest of the @ai2 registry. They share the same token file, so a styled action next to a base button or a badge stays visually consistent in both modes.
