License, pricing and purpose

License
MIT · ✓ OSI-approved
Permissive: Use, change and redistribute freely, keeping the notice.
Access
Open core
An open license for the core, with paid extras from the same publisher.
Purpose
Arc is a standalone React component kit and block collection with built-in motion, styled using CSS modules and custom design tokens instead of Tailwind CSS.
Commercial model
Freemium
A free part plus paid extras from the same publisher: pro components, premium blocks or templates, an all-access pass or a paid license tier.
Tied to a service
No
Yes when the components are a client for a commercial API or service.
Scope
Complete kit
A broad, general-purpose component set that covers most everyday primitives (buttons, inputs, dialogs, menus, tables) and can be the main UI kit of an app, whether it restyles shadcn/ui or extends it.
Domains
Animation, Charts
Animation: Animated components, motion effects and transitions. Charts: Charts, graphs and data visualization.
Design
Distinct look
Has its own visual language that no longer reads as shadcn/ui, such as neobrutalism, retro pixel art, glassmorphism or skeuomorphism.
Coverage
48%
Share of shadcn/ui core primitives that the registry ships.
Design distance
1.00
Measured on sample items: 0 is identical to vanilla shadcn/ui, 1 is entirely different.
