What is Code Designer?

Flight Deck Alpha — write .mud in Monaco, preview HTML live, ask CeeDee stupid questions. BYOK. No shame.

Code Designer is the IDE-shaped sibling of Grav MUD. Same spec language. Different runway — Next.js + Monaco instead of PHP on your cPanel. Built because sometimes you want to draft the page before Grav even boots.

One language, two runtimes

Grav MUD (this site)Production CMS — .mud pages, themes, cache, deploy
Code DesignerAuthoring shell — split editor, live preview, agent assist

Both talk to packages/mud-parser in the Code Designer repo — TypeScript reference implementation. PHP compiler in grav-mud-alpha targets the same fences. Parity is the product.

What's in Flight Deck Alpha

  • Monaco editor.mud and .non buffers with syntax that doesn't pretend to be JSON.
  • Live HTML preview — see fences compile without php bin/grav clearcache ritual.
  • Composer 2.5 panel — Cursor SDK agent (BYOK) that reads your open buffers. Ask it to add a pricing block. Regret nothing.
  • Extensions API stub — future plugin hooks for templates, export, CURSY microsites.

Why it exists

Grav admins aren't always at localhost:8090. Writers aren't always in Admin Panel. Agents definitely aren't clicking "Add Modular."

Code Designer is the workbench — draft spec, preview layout, copy into user/pages/foo/default.mud, or run the static exporter and ship HTML.

Static export — the handshake

Lone Mamber proved the pipeline: Grav renders → PHP export script → web/ folder → node server.mjs.

We ported that exporter here too (scripts/export-static.ps1). Write in Code Designer. Compile in Grav. Export static. Host anywhere.

That's not betrayal of flat-file CMS — it's optionality. Grav when you want CMS. HTML when you want cheap hosting and zero PHP drama.

Who it's for

  • You — if you've ever said "I'll just tweak the Twig" and lost an hour.
  • Agencies on Seed/Studio tiers — client handoff includes .mud + theme, not a Elementor lock-in.
  • Future you — when Flex Pages lands and you want migration tools that speak spec, not scrape DOM.

Try it: clone CodeDesigner-app, npm run dev, open /editor. Paste a fence from /spec. Watch it breathe.
