AtroUI is a production-ready dark-first component catalog on the shadcn registry that lets you copy raw React and Next.js files directly into your repository. You retain 100% source code ownership.

How does AtroUI differ from copy-paste UI kits?

Unlike typical copy-paste kits that provide only primitive atoms (like basic buttons or inputs), AtroUI provides fully designed blocks (heroes, pricing layouts, footers) and hardened Host API backend handlers for forms and AI workspaces under a Bring Your Own Keys (BYOK) paradigm.

Does AtroUI require installing an npm dependency?

Pure UI layout blocks have no npm dependencies; they copy raw code. Only form components or AI workspaces that use our pre-hardened routes require installing the helper library 'atroui' to run rate-limiting and SMTP validation safely on your server.

What AtroUI is

A production component catalog for React / Next.js, delivered the shadcn way: dark-first sections, site chrome, and optional Host API tools that expect your own backends. You add components with the CLI; source lives in your repo.

What copy-paste kits optimize for

Many kits excel at primitives you own in your repo - buttons, dialogs, forms - generated into your codebase. That is a strong workflow for greenfield design systems you maintain yourself.

Where AtroUI differs

Same ownership model - npx shadcn add @atroui/… copies source into your project. Edit CONTENT at the top of each file. See the Registry guide.
Blocks, not only atoms - heroes, who bands, footers, CTAs shaped by shipped products.
Brand chrome - getBrand() + env overrides so logos, SEO, and mail defaults stay coherent.
Dark-first system - tokens and surfaces designed for black-canvas products.
Host API tools - workspaces that call your /api/* with BYOK; docs do not burn shared LLM keys. See Host APIs.

When to pick which

Prefer a blank-slate kit if you want every primitive from scratch. Prefer AtroUI when you want a ready dark catalog with the same copy-into-repo workflow. Start at the registry. Home: www.atroui.com.
