Design Atlas

← Atlas

Components ​

Component libraries, registries and design systems for building UI — from single copy-paste snippets to full production design systems.

Start here ​

  • shadcn/ui — the de-facto foundation other libraries in this atlas build on top of; copy-the-code model, agent-ready.
  • The Component Gallery — compare how dozens of mature design systems name and structure the same component before designing your own.
  • Astryx — a comprehensive production system with strong accessibility hooks and a sophisticated table component.
  • React Bits — hundreds of animated components with an llms.txt index for agents.
  • Carbon Design System — IBM's mature Apache-2.0 system, with about 50 components, pattern pages for whole flows and an llms.txt that maps every component to its package.

Patterns worth reusing ​

  • Copy code into the repo instead of installing a closed package, so the component stays fully editable (shadcn/ui, mapcn).
  • Compare how several mature design systems name and structure the same component before fixing your own API (The Component Gallery).
  • Split a catalog into components (atoms), blocks (full sections) and templates (whole pages), each with its own level of "already assembled" (UIAble).
  • Extend an established registry model (like shadcn's) into a specific domain, such as maps, instead of only generic UI (mapcn).
  • Offer install at multiple depths — copy-paste, npm, CLI — so developers pick their own level of control (Aceternity UI).
  • Build agent-aware pieces (plan cards, citations, diffs) directly into the catalog for AI product interfaces (Kobra, Astryx).
  • Use hook-based plugin extension (sort, select, resize, tree) for complex components like tables instead of a growing prop list (Astryx).
  • Add a command palette to navigate a large catalog rather than relying on categories alone (UIAble).
  • Design small and large variants of a component separately rather than scaling one drawing down (Libraries.dev: Thinking orbs).
  • Publish an llms.txt that lists each component with its install command, source link and dependencies, so an agent can pick and install the right piece (Rare UI).
  • Let a generator render and screenshot its own output, then compare it with the target and fix the differences (Screenshot to Code).
  • Wrap a proven headless library in shadcn-style parts for complex widgets such as Gantt charts, Kanban boards and editors, and export each as small pieces teams can rearrange (Kibo UI).
  • Export a headless hook that owns the behaviour next to a styled example, so reskinning only means changing classes (interior.dev).
  • Take the registry model beyond web UI: email (emailcn), PDF (pdfcn), Open Graph cards (ogimagecn), terminals (termcn), video (Remocn, framecn) and sound (sensory-ui, soundcn).
  • Keep one token set and compile it for each renderer, so a theme works across engines without a redesign (emailcn, pdfcn).
  • Before building a component, check it against a list of states, traps and ARIA requirements, with accessibility items inside each component's checklist (UI Playbook, Design System Checklist, Inclusive Components).
  • Give each component page separate usage, style, code and accessibility tabs, and document flows such as empty states and loading as patterns, not single components (Carbon Design System).
  • Hand agents a copy-prompt that includes the full source and tells them to map the component's tokens onto the project's own (Bencho).

Pitfalls ​

  • Copied-code libraries don't update automatically — you have to re-copy or manually merge changes later (shadcn/ui, mapcn).
  • Heavier animation dependencies (Framer Motion, GSAP, three.js) add real bundle weight if many effects are used at once (Aceternity UI, React Bits, UIAble).
  • Community-submitted catalogs vary widely in accessibility and maintenance quality — check provenance before adopting (Uiverse, community galleries generally).
  • Some libraries carry restrictive licences (Commons Clause, proprietary tiers) — treat them as ideas and reference implementations, not code to repackage (React Bits, Kobra, Rare UI).
  • Generated components are written for the stack you pick, not your existing components and tokens, so expect to restructure them (Screenshot to Code).
  • Small catalogues can pull in several extra dependencies per component; check the list before installing (Rare UI).
  • Many new shadcn-style registries are young, single-maintainer projects, and some namespaces aren't in shadcn's public directory, so the registry entry has to be added by hand (pdfcn, editorcn).
  • Registry metadata can be wrong: framecn items declared remotion as a dependency while importing @editframe/react, so check package.json after installing.
  • The engine underneath may need its own licence even when the components are MIT: Remotion for companies above three employees (Remocn), Editframe above three people (framecn).
  • "Free" can still restrict reuse: Canvas UI adds the Commons Clause, Transitions.dev forbids redistributing the collection, and Orbkit and shadercn include non-commercial orbs.
  • Carbon's packages run a telemetry postinstall script; set CARBON_TELEMETRY_DISABLED=1 to opt out.
