March 2026 - shadcn/cli v4
We're releasing version 4 of shadcn/cli. More capable, easier to use. Built for you and your coding agents. Here's everything new.
shadcn/skills
shadcn/skills gives coding agents the context they need to work with your components and registry correctly. It covers both Radix and Base UI primitives, updated APIs, component patterns and registry workflows. The skill also knows how to use the shadcn CLI, when to invoke it and which flags to pass. Agents make fewer mistakes and produce code that actually matches your design system.
You can ask your agent things like:
- "create a new vite monorepo"
- "find me a hero from tailark, add it to the homepage, animate the text using an animation from react-bits"
- "install and configure a sign in page from @clerk"
Introducing --preset
A preset packs your entire design system config into a short code. Colors, theme, icon library, fonts, radius. One string, everything included.
Build your preset on shadcn/create, preview it live and grab the code when you're ready.
Use it to scaffold projects from custom config, share with your team or publish in your registry. Drop it in prompts so your agent knows where to start. Use it across Claude, Codex, v0, Replit. Take your preset with you.
Switching presets
When you're working on a new app, it can take a few tries to find something you like so we've made switching presets really easy. Run init --preset in your app, and the CLI will take care of reconfiguring everything, including your components.
Skills + Presets
Your agent knows how to use presets. Scaffold a project, switch design systems, try something new.
- "create a new next app using --preset adtk27v"
- "let's try --preset adtk27v"
New shadcn/create
To help you build custom presets, we rebuilt shadcn/create. It now includes a library of UI components you can use to preview your presets. See how your colors, fonts and radius apply to real components before you start building.
New --dry-run, --diff, and --view flags
Inspect what a registry will add to your project before anything gets written. Review the payload yourself or pipe it to your coding agent for a second look.
Updating primitives
You can use the --diff flag to check for registry updates. Or ask your agent: "check for updates from @shadcn and merge with my local changes".
shadcn init --template
shadcn init now scaffolds full project templates for Next.js, Vite, Laravel, React Router, Astro and TanStack Start. Dark mode included for Next.js and Vite.
Use --monorepo to set up a monorepo.
shadcn init --base
Pick your primitives. Use --base to start a project with Radix or Base UI.
shadcn info
The info command now shows the full picture: framework, version, CSS vars, which components are installed, and where to find docs and examples for every component. Great for giving coding agents the context they need to work with your project.
shadcn docs
Get docs, code and examples for any UI component right from the CLI. Gives your coding agent the context to use your primitives correctly.
registry:base and registry:font
Registries can now distribute an entire design system as a single payload using registry:base. Components, dependencies, CSS vars, fonts, config. One install, everything set up.
Fonts are now a first-class registry type. Install and configure them the same way you install components.
