  • designesy_compare

    Diff two design systems from live URLs, using the only URL-scoped design-token diff engine. Fetches both URLs in parallel, extracts their :root custom properties, and produces a structured diff across 8 dimensions: tokens added (in A not B), removed (in B not A), renamed (heurist

  • designesy_report

    Generate a unified design-intelligence report for a single URL, the synthesis capstone. Fires /score (45-check audit), /drift (12-check drift radar), and /readiness (10-check AI readiness) in parallel, then computes a weighted composite: score × 0.5 + drift × 0.3 + readiness × 0.

Preguntas frecuentes

¿Es seguro Designesy?

Superó 3 de 3 revisiones básicas aplicables. No hemos leído el código. Antes de agregar una clave o un token, revisa qué acceso pide el servidor y usa una clave que tenga solo los permisos que necesitas.

¿Qué claves o códigos necesita?

El registro no indica ninguna clave obligatoria, aunque algunos servidores te piden iniciar sesión la primera vez que los usas.

¿Se ejecuta en mi computadora o en la nube?

Funciona de las dos formas: instálalo en tu computadora o conéctate a la versión en la nube.

¿Sigue en mantenimiento?

El repo de GitHub cambió por última vez –, y la última versión (1.13.10) llegó al registro hace 17 días.

¿Qué apps pueden usarlo?

Las apps compatibles con MCP, como Claude Desktop, Claude Code, Cursor y VS Code. Se conecta por URL, así que también funcionan las apps que aceptan servidores MCP remotos, como ChatGPT en modo desarrollador.

Designesy

A 12-second loop, recorded from the homepage. It plays once and rests on the verdict, and shows a still frame if you prefer reduced motion. Watch it run on designesy.org .

Design quality gate for AI-generated UI: score any URL on 45 deterministic checks, A–F grade. Live at designesy.org.

Quick Start

Score any URL in 5 seconds — no install:

npx @designesy/score@latest https://your-site.com

Add to Claude Desktop, Cursor, or any MCP client:

# Claude Code, remote (zero install, no auth):

claude mcp add --transport http designesy https://www.designesy.org/api/mcp

Or local stdio via PyPI:

pip install designesy-mcp && designesy-mcp

Clone this repo? The .mcp.json at root adds the local server (uvx designesy-mcp) to Claude Code as a project server. Claude Code asks you to approve it the first time you open the project. It needs uv.

Gate your CI on design-contract compliance:

- uses: LE-VAI/designesy-org@v1

with: url: https://your-app.vercel.app min-score: 70 min-grade: C post-comment: true # posts a summary comment on PRs (default)

The same 45-check engine powers an MCP server (17 tools for AI agents), a CLI with no required dependencies (npx @designesy/score), and a GitHub Action.

Designesy Contract Check is a GitHub Action that scores any URL against a 45-check design-system contract (tokens, motion, accessibility, cadence, takt, poise, identity, interaction, performance, responsive, semantic, security, spec, copywriting) and fails your CI workflow when the score or grade drops below your threshold. No LLM in the loop: every check is a published, deterministic rule, so the same page gives the same verdicts.

Live

Contract verification

The live site is verified against the design system contract — 45 deterministic checks with provenance back to tokens. Both badges read the site's own recorded score from /api/badge?site=designesy.org, which carries the date it was measured; for a fresh reading with every check, score designesy.org now. See the methodology page for how the score is computed.

The contract

  • 45 verification checks across 14 weighted categories — tokens, motion, accessibility, cadence, takt, poise, identity, interaction, performance, responsive, semantic, security, spec, copywriting
  • Copywriting principles (added in v0.4.0) — 16 UX copy principles + 4 verification checks (button verb phrases, no trailing periods, descriptive link text, no ALL CAPS)
  • 10 Non-Negotiable Motion Standards — deliberate easing, explicit properties, opacity entrances, keyboard stillness, no layout animation, touch gating, bounded duration, reduced-motion paths, asymmetric press, no ease-in
  • 10 acoustic cue tokens — custom $type: sound (net-new vs W3C DTCG 2025.10), Cuelume 0.2 engine (MIT), interaction-only. The acoustic token document adds 9 extended feedback cues, 19 in all
  • 10 open tensions — documented, not hidden
  • Spring physics — default + momentum tokens via custom $type: spring
  • Machine-readable — W3C DTCG 2025.10 format + custom extensions

See the contract page for the full adoption history.

GitHub Action

Gate your CI on design-contract compliance:

- uses: LE-VAI/designesy-org@v1

with: url: https://your-app.vercel.app min-score: 70 min-grade: C post-comment: true # posts a summary comment on PRs (default)

Scores a URL via the live /api/score engine and fails the workflow if the score or grade drops below your threshold. Runs on node24, posts PR comments via bare GitHub REST API (zero dependencies). See action/README.md for full usage.

CLI

Score a URL from the command line — for local development, pre-commit hooks, or scripts:

# No install needed:

npx @designesy/score designesy.org

With gating (exit 1 on failure):

npx @designesy/score linear.app --min-score 70 --min-grade B

JSON output for piping:

npx @designesy/score vercel.com --format canonical --json

No required dependencies. The engine runs locally, with no Designesy server; the checks that need a browser return MANUAL. See --help for all options and packages/score/README.md for the full reference.

From a clone of this repo: the engine's dist/ folder is not committed, so build it first.

npm --prefix packages/score ci

npm run build:score node packages/score/dist/cli.js designesy.org

The older cli/designesy-score.mjs (npm run score) reads the same build. It is superseded by @designesy/score. Its --api flag (or the SCORE_API env var) is an opt-in remote fallback that sends the URL to a scoring server instead of scoring locally; it is off by default.

Repository

The site is a Next.js 16 App Router app (React 19, webpack build), deployed on Vercel. The npm packages and the MCP server live beside it.
