UI Builder — Visual Editor for Your React App
UI Builder is a shadcn/ui package that adds a Figma-style editor to your own product, letting non-developers compose pages, emails, dashboards, and white-label views with the exact React components you already ship.
Layouts are saved as plain JSON for easy versioning and can be rendered instantly with dynamic data.

UI Builder is now part of BTST — ship full-stack features faster with production-ready plugins that generate database schemas, API routes, and pages for Next.js, TanStack Start, and React Router.
Installation
Quick Start with shadcn/ui
If you already have a shadcn/ui project:
npx shadcn@latest add https://raw.githubusercontent.com/olliethedev/ui-builder/main/registry/block-registry.json
Or start a new Next.js project with UI Builder:
npx shadcn@latest init https://raw.githubusercontent.com/olliethedev/ui-builder/main/registry/block-registry.json --base-color zinc
Optional: Add All Shadcn Components
Install the full shadcn component library with 54 pre-configured components and 124 block templates:
npx shadcn@latest add https://raw.githubusercontent.com/olliethedev/ui-builder/main/registry/shadcn-components-registry.json
Handling Peer Dependencies
If you encounter peer dependency warnings (common with React 19), create a .npmrc file:
echo "legacy-peer-deps=true" > .npmrc
Note: Use style variables for proper page theming.
Basic Usage
import z from "zod";
import UIBuilder from "@/components/ui/ui-builder";
import { Button } from "@/components/ui/button";
import { ComponentRegistry } from "@/components/ui/ui-builder/types";
import { primitiveComponentDefinitions } from "@/lib/ui-builder/registry/primitive-component-definitions";
const myComponentRegistry: ComponentRegistry = {
...primitiveComponentDefinitions,
Button: {
component: Button,
schema: z.object({
className: z.string().optional(),
children: z.any().optional(),
variant: z.enum(["default", "destructive", "outline", "secondary", "ghost", "link"]).default("default"),
}),
from: "@/components/ui/button",
},
};
export function App() {
return <UIBuilder componentRegistry={myComponentRegistry} />;
}
