ReactΩ

Motion · Interaction · Physics

The AI-native React component registry. 31 copy-paste components you own outright — installable in one line by humans and AI agents.

Open the live playground Source on GitHub npx -y github:Edwson/ReactOmega add split-textcopy

Move your cursor — the wordmark is a live component (variable-proximity)

01 — THE WEDGE

A component library, built for the machine age.

Tools like shadcn and react-bits give you components you own — no black-box package. ReactOmega keeps that, then adds the layer they don't ship: a machine-readable registry, a CLI, an MCP server, and an llms.txt. The same components install for a human reading docs and for an AI agent reading contracts.

02 — ONE SOURCE OF TRUTH

Everything is generated from one file.

A single meta.json plus the component sources are compiled into the registry, the shadcn items, and the agent guide — deterministically. The CLI, shadcn, and the MCP server all read the same output, so they can never drift. CI re-runs the build and git-diffs it on every push.

03 — THE MACHINE LAYER

Installable by humans and agents.

Three front doors to the same registry. Add ReactOmega to Claude Desktop or Cursor and ask: "add a ReactOmega magnetic button." The agent calls the MCP server, which reads the exact contract the CLI reads.

① CLI
npx -y github:Edwson/ReactOmega add magnetic
Resolves a component + its primitives, writes them into your repo. Zero-dependency.
② shadcn
npx shadcn add …@v1.0.0/r/tilt-card.json
Items are shadcn-compatible — served straight from jsDelivr.
③ MCP server
list_components
get_component
add_component
Tested end-to-end against the real MCP SDK client.
04 — THE PROOF IS THE PAGE

Everything you've been touching is the library.

The hero wordmark, the cursor, the field behind it — all hand-built from ReactOmega's own components. Here are a few more, live. 31 ship in the playground.

05 — THE CONTRACT

Accessibility isn't a setting. It's a test.

Every component honors prefers-reduced-motion — and a dependency-free test in CI fails the build if any component doesn't reference it. The contract caught a real gap during development and forced the fix.

This case study honors it too. Turn on Reduce Motion and the field freezes to a single frame, the cursor returns to default, and the wordmark stops bending — the contract applies to the page, not just the components.

06 — TWO LANES

Deliberately not GalaxyJS.

Same author, two open-source libraries, two problems. Kept strictly separate so neither dilutes the other.

ReactΩ

React-first registry

Motion, interaction & physics UI you copy into a React app — with an AI-native distribution layer.

  • React + TypeScript + Tailwind
  • Copy-paste, you own the code
  • Registry + CLI + shadcn + MCP
  • Reduced-motion by contract
GalaxyJS

Vanilla cosmic canvas

A zero-dependency, framework-free library of 60 cosmic canvas animations + UI kit.

  • Plain JS, no framework
  • Drop-in <script> / CDN
  • Cosmic backgrounds & effects
  • Its own MCP + playground
07 — SHIPPED

Not a concept. Released.

01
v1.0.0 · MIT

Tagged release with a 31-component registry. Release notes ↗

02
Live playground

Every component rendered live, auto-deployed via GitHub Pages. edwson.github.io/ReactOmega ↗

03
CI on Node 18 · 20 · 22

Syntax check, esbuild-compile every component, a registry-drift gate, a dependency-free contract test, and a real end-to-end MCP test — green on every push.

04
Built solo, AI-augmented

Architected and shipped end-to-end with an AI pair (Claude Code + agents), disclosed openly. The registry is the source of truth; the human owns the judgment.

08 — WHAT THIS EVIDENCES

I designed a design system as a product.

The differentiator was never "more components." It was treating distribution, machine-readability, and an accessibility contract as first-class product decisions — then building the toolchain (registry → CLI → shadcn → MCP) that keeps them honest and drift-free. That's the same instinct I bring to regulated product surfaces: the system is only as good as the discipline that guarantees it.
