Spectrum UI

Spectrum UI is a collection of reusable components combining elements from Aceternity UI, Magic UI, and ShadCN UI into a unified, copy-and-paste component library for modern web applications. It is an open source template in the shadcn.io collection of 215.

Spectrum UI is made by Arihantcodes, an independent developer; shadcn.io lists it but did not make it. Arihantcodes has 1 template in the collection, and the author's page lists them.

The listing tags Spectrum UI with Next.js, React, Tailwind, Block Library and UI Kits & Component Libraries. Those are its categories, not a dependency list: the exact packages and versions are in the repository's package.json.

Yes. The Spectrum UI page embeds its live demo from ui.spectrumhq.in, and links to it so you can open the real deployment before you clone.

The Spectrum UI listing was last updated on October 8, 2025. That date is the listing's, not the repository's: check the repository's commits for recent activity.

Clone the repository (git clone https://github.com/arihantcodes/spectrum-ui), then follow the README. The Spectrum UI page shows the usual steps and a terminal block with the commands to copy.

Install dependencies with npm install or pnpm install, then run npm run dev. The README in the Spectrum UI repository says which package manager and environment variables it needs.

No. Spectrum UI is cloned from its own GitHub repository, so shadcn.io isn't involved. Browsing the page and its live demo need no account either; Pro adds the premium templates, the blocks and the MCP server.

Spectrum UI is tagged Next.js, so it deploys wherever a Next.js app does, such as Vercel, a Node.js server or a container. Its README may add steps for its own services.

The Spectrum UI listing doesn't record a license. Check the LICENSE file in its repository (https://github.com/arihantcodes/spectrum-ui), and ask the author if there isn't one.

That depends on Spectrum UI's license in its repository, which shadcn.io does not set. Read the LICENSE file before you use it in a client or paid project, and ask the author if it is unclear.

Attribution follows Spectrum UI's license. Many permissive licenses ask you to keep the copyright notice and license text in your copy; its LICENSE file says exactly what.

No. The Pro license covers shadcn.io's own Pro code, blocks and premium templates. Spectrum UI is the author's project, under the terms in its repository.

Arihantcodes supports Spectrum UI, through its GitHub repository: read the docs, open an issue or look for discussions. shadcn.io does not maintain it.

Yes. Once you clone it, Spectrum UI is your own code: change the theme, add pages and connect your backend. It uses shadcn/ui, so you can also add more components the same way.

Yes. Components are free with a free account and the blocks are in Pro; both are copied into your project with the shadcn CLI. Check that Spectrum UI uses Tailwind CSS and the shadcn/ui setup (a components.json) before you add them, and pick the base library your project already uses.

Yes, with Pro. The shadcn.io MCP server's search_templates tool finds templates by what they are, and returns each one's repository and live demo, so your editor can set up Spectrum UI for you. Your files stay on your machine.

The collection has 5 other open source Block Library templates like Spectrum UI, shown at the foot of its page with the ones sharing most categories first. All of them are at /template/category/block-library.

Arihantcodes has no other templates in the collection.

Yes. The 14 premium templates (Solaris, Reframe Labs, Spherule and Max and more) are built by shadcn.io and come with every Pro plan, if you want maintained code with a design file.
