What's inside

Everything you need. Nothing you don't.

Full-stack primitives, designed for a world where most code is written by AI.

⚡

Full-stack in 1 file

Tables, auth, API routes, and UI in a single .nyx file. Compiles to Express + SQLite + static HTML.

🎨

Design tokens

Themes with colors, spacing, radius, shadows, fonts. Dot-notation refs. 7 built-in presets.

🤖

AI-native

82% fewer tokens than Next.js. Shorthand properties everywhere. Built for Claude, GPT, and Gemini.

🍔

Zero-JS burger nav

One attribute → responsive mobile nav. Pure HTML5 details/summary. No runtime, no JavaScript.

🎭

Figma import

Import Tokens Studio or W3C DTCG JSON directly. Colors, spacing, shadows — validated and security-audited.

🧱

Components & presets

Define once, use everywhere. Parameterized components with defaults. Style presets = reusable CSS classes.

🔒

Security built-in

JWT auth, bcrypt, rate limiting, SQL injection guards, TOCTOU-safe file loading. Audited 9.5/10 by Tyto 🦉.

📁

Multi-file modules

use "./file.nyx" imports for bigger projects. nyx flatten collapses back to one file.

🚀

Zero config

No webpack, no Vite, no Babel. Compile with nyx build. Dev server with hot reload built in.

Live example

A full-stack blog. 16 lines.

Database. Auth. JWT. 10 CRUD endpoints. Login, register, and a post feed. Really.

blog.nyx 169 tokens

table posts { title text required, body text, created auto }
security { table users, login email password, token jwt, protect /api/posts write }
theme { colors { primary: #667eea, bg: #0a0a12, card: #1a1a2e } }
preset card { bg card, r 12px, p 2rem }

page / {
  section style={ mw 800px, mx auto, p 2rem } {
    h1 "My Blog"
    form /api/posts auth { input title, submit "Post", success -> reload }
    data posts = get /api/posts auth
    each posts -> div preset=card { h3 .title, p .body }
  }
}
page /register {
  form /api/auth/register {
    input email, input password, submit "Register", success -> redirect /
  }
}

✓ 10 CRUD endpoints ✓ JWT auth ✓ SQLite schema ✓ Bcrypt hashing ✓ Multi-page routing
