Jakubantalik/Libraries.dev

High-crafted UI libraries for AI agents. Seven React libraries for the effects that make an interface feel alive: a beam of light travelling a card's border, orbs that think while a model works, bot avatars with living faces, shapes that merge like liquid, a glow that rises with your voice, brushed metal that catches the light, and an image loader that dissolves a pixel mosaic into a real photo.

Each one installs from npm and drops into your app as a single component that wraps the element you already have. Your markup keeps its semantics, the effect renders around or behind it, and the whole thing is tuned by props rather than hand-written WebGL.

Try each one on libraries.dev: a live preview to play with, the install command, the usage code, and a playground that copies the exact configuration.

Every library ships as a prompt. Copy it, paste it into your coding agent, and make it yours — three steps, no setup.

1. Copy the prompt. Every library page has a Copy prompt button. One paste gives your agent the whole library: its parameter vocabulary and your current settings.
2. Paste it into your agent. Drop it into Claude Code, Cursor or Codex. The agent installs the package and wires it in, matched to your theme.
3. Make it yours. Open the Studio with Pro for every knob, tune it live and copy the result as props.

Or the plain way:

npm install border-beam   # or thinking-orbs, bot-avatars, liquid-gooey, voice-glow, metal-fx, img-fx

import { BorderBeam } from "border-beam";

<BorderBeam>
  <button>Get started</button>
</BorderBeam>

Each package's README documents its props.

What do I need? React 18 or newer. Each library is a standalone package with zero runtime dependencies, except Image, which also needs three as a peer dependency.

Do they work with coding agents? Yes — that is the point. Every library installs and configures cleanly from Cursor, Claude Code and Codex, and each playground's copy-prompt button hands your agent the library's full parameter vocabulary along with your current settings.

Light and dark mode? Both, detected for you. The default theme="auto" resolves a data-theme attribute or dark class on an ancestor, then falls back to prefers-color-scheme, updating live when either changes. Pass theme="dark" or theme="light" to pin one.

What are Pro and the Studio? One plan across every library. Pro unlocks the Studio — deep, per-library customization beyond the public playgrounds, with export of the exact configuration — plus Pro presets and every future library and update. See pricing.

Commercial projects? The libraries are MIT — use them anywhere, including commercial work. Pro content (Studio exports, Pro presets and recipes) is licensed to you or your team under the plan you buy, for unlimited projects.

npm workspaces: packages/ holds the published libraries (one folder per npm package, each with its own README and LICENSE), sites/ the demo sites — sites/home is libraries.dev.

npm install
npm run build:site-home         # every library + libraries.dev, as CI does
npm run dev -w @sites/home      # libraries.dev with every page and the Studio
npm run typecheck               # every workspace

The home site imports the built packages, so build a library (npm run build:beam, build:orbs, build:gooey, build:voice, build:metal, build:image) before its page or bench. The standalone demos (@sites/beam, @sites/gooey, @sites/orbs) alias their library to its source and hot-reload without a rebuild.

Publishing is per package (publish.yml, npm publish -w <package>): run the workflow by hand with the package name, or publish a GitHub release whose tag is <package>@<version> (voice-glow@0.2.0). A version the registry already has is skipped.

The two sites are hosted separately, because GitHub Pages serves one custom domain per repo:

• beam.jakubantalik.com — GitHub Pages via .github/workflows/deploy.yml; the domain binding lives in sites/beam/public/CNAME.
• gooey.jakubantalik.com — Cloudflare Pages, built from this repo with npm run build:site-gooey, output sites/gooey/dist.
• orbs.jakubantalik.com — Cloudflare Pages, built with npm run build:site-orbs, output sites/orbs/dist.
• libraries.dev — Cloudflare Pages, deployed by .github/workflows/deploy-home.yml on every push to main (npm run build:site-home, output sites/home/dist). The main site: landing, a page and Studio bench per library, Pro pricing, account and legal pages. Its backend is api.libraries.dev, a Worker in the private libraries-pro repo — see sites/home/README.md.

.node-version pins Node 20 for the Cloudflare builds, matching the version the GitHub workflows use; Cloudflare's default is older.

Cloudflare's Retry deployment replays the same commit rather than fetching the branch tip, so a build that failed on an outdated commit keeps failing. Push a new commit to get a fresh one.

Only the beam site carries a public/CNAME; that file is a GitHub Pages mechanism. The Cloudflare-hosted sites bind their domain in the Pages project instead, and the DNS record itself lives at the registrar (inetadmin), not Cloudflare — jakubantalik.com is not on Cloudflare's nameservers.

thinking-orbs arrived by git subtree, so its full history is in this repo — but those commits touched src/…, not packages/thinking-orbs/src/…. git log -- packages/thinking-orbs therefore stops at the merge. To read the real history, log from the commit the merge names:

git log --oneline 9c6d5c3 -- ports/ios/PillsDemo/Sources/PillsApp.swift
git log --follow packages/thinking-orbs/src/index.ts

thinking-orbs also carries native ports under packages/thinking-orbs/ports — a React Native package and a SwiftUI package, kept in step with the web renderer by the golden vectors in spec/. Neither is published yet.
