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.
How to use
Every library ships as a prompt. Copy it, paste it into your coding agent, and make it yours — three steps, no setup.
- 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.
- 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.
- 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.
FAQ
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.
What about the models? The code around them (MagnetKit for iOS and Android) is MIT. The model files themselves, starting with Magnet.mfxl for Magnetic UI, are under the Libraries.dev Model License: free for development, prototypes and non-commercial apps; shipping one in a commercial app needs Pro or Business. They are downloaded from libraries.dev and never committed to this repo.
Working in this repo
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.
Releasing
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> ([email protected]). A version the
registry already has is skipped.
Deploys
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.
