Sponsor ThreeUI: Linked README placements start at $500/month, with website placements from $1,500/month. View sponsorship plans.

The open-source, login-free edition of ThreeUI. It uses the same application shell, layout, navigation, browse grid, search, themes, responsive behavior, component pages, live renderers, controls, variant picker, and source tabs as the main project.

The catalog is the only product-level difference: Pro and Beta components are removed. Every Community component keeps all of its free variants and controls.

Sponsorship keeps the open-source Community library maintained and puts your product in front of ThreeUI's developer audience. Website traffic is currently estimated at roughly 90,000 views per day as of 26 August 2026; this is directional traffic context, not a guarantee of sponsor impressions, clicks, or results.

See the complete sponsorship details or email support@designcode.io. Sponsorship does not guarantee roadmap changes, editorial control, exclusivity, or private support.

npm install
npm run dev

Run the complete publication boundary, type, and production-build checks:

npm run build

Install the public Community component library from npm:

npm install @designcodeio/threeui

Import a component and the shared styles:

import { AtTheHorizon } from "@designcodeio/threeui";
import "@designcodeio/threeui/style.css";

export function Hero() {
  return <AtTheHorizon />;
}

For the smallest development import graph, use a component subpath:

import { AtTheHorizon } from "@designcodeio/threeui/components/AtTheHorizon";

Components that render full HTML documents expect their runtime files at the same root-relative URLs used by the ThreeUI preview. Copy the needed files from node_modules/@designcodeio/threeui/lib-dist/assets/ into your app's public directory, or override the component's sourceUrl or assetBaseUrl prop where available.

Pro implementation source is deliberately not published to npm. Active ThreeUI Pro members authenticate through the browser and download an entitled source bundle with the public CLI:

npx @designcodeio/threeui-cli add cross-beam

The CLI uses OAuth with PKCE, stores its refreshable session with owner-only permissions, checks the account entitlement on every server request, and refuses to overwrite changed project files unless --force is supplied. Run npx @designcodeio/threeui-cli --help for login, logout, destination, and development endpoint options.

The checked-in repository runs independently. Maintainers can refresh its Community subset from a separately held main-project snapshot:

npm run sync:community -- /path/to/main-threeui

The sync fails closed, filters Pro and Beta before generating the public import graph, preserves all free metadata and options, removes restricted font assets, and writes:

• public/community-sync-report.json — counts plus per-component variant/control parity
• public/source-code.json — Community source bundles used by the Code tab
• src/data/shaders.tsx — Community-only catalog and renderer imports

The private ThreeUI repository runs this synchronization after every successful push to main. A no-op sync exits without a release. Changes update the automation/community-sync branch and open one reviewed pull request here. New public components, variants, or controls infer a minor release; removals infer a major release; compatible source changes infer a patch release. Merging a versioned sync pull request publishes the new package through npm trusted publishing with provenance.

The public workflow also runs a clean build, boundary audit, package creation, and anonymous installation smoke test before release. The Pro installer is versioned and published separately; changes to Pro component content do not require a CLI release.
