What it does
shadcn/ui distributes interface component code that teams can modify within their own projects. Its documentation emphasizes composition, open code and a registry format for distributing components.
shadcn/ui gives you component code that can be edited inside your project. The components have default styles and a composable structure, while registries distribute code and its dependencies to other projects.
Run pnpm dlx shadcn@latest init to configure an existing project, or use its new-project options. Initialization sets up dependencies, the cn utility and CSS variables. pnpm dlx shadcn@latest add button adds a component and its dependencies. Before changing files, add --dry-run previews the work; --diff shows differences and --view shows file contents. These controls are useful when a component already contains local changes.
For an internal library, shadcn build reads registry.json and generates distributable registry files. You can also inspect components with view or search a named registry from the command line.
The project is MIT-licensed, and the public component installation workflow needs no account. Direct control of the code also means your team must review how later changes interact with its own edits; overwriting existing files is an explicit CLI option.
Strengths
- Teams receive component code they can inspect and modify.
- A composable interface and registry format support reusable component distribution.
- CLI previews and diffs show proposed file changes before they are applied.
Watch out for
- Locally modified components require deliberate handling of later upstream changes.
Best for
- Teams that want direct ownership of their shared interface code
