Flat-file CMS · getgrav.org

Built on
Grav

Grav MUD is not a separate CMS — it's a content format + compiler plugin that respects Grav's page tree, YAML frontmatter, Twig themes, and cache. The official promo site you're reading is 100% Grav, 100% .mud.

Why Grav is the right host

Pages stay files

Git-friendly. FTP-averse. Your .mud lives next to user/pages like always — no database export ritual.

Event pipeline

onPageContentRaw compiles MUD to HTML before markdown/Twig processing — clean hook, no core hacks.

Themes stay themes

CSS is still CSS. Twig is still Twig. MUD only replaces the middle — the unstructured markdown soup.

Path to core

Alpha proves demand. Flex parity + tests = conversation with Trilby Media. Andy's conniption = market validation.

Core integration (future-facing)

This PoC is a pitch fork, not a drop-in Grav 2 PR today.

Today (Alpha)

Plugin registers .mud extension
MudAlphaCompiler + MudDesignSpec render fences
Theme provides layout CSS

Tomorrow (if adopted)

Official page type in Admin
Flex Objects compatibility
Shared parser package with Code Designer
Documentation on learn.getgrav.org

We're not asking Grav to become Webflow. We're asking for a first-class structured page format — the way .md was first-class, but for design specs.

Friendly fork energy. Buy Andy a coffee before saying "Grav 2.0 just dropped MUD."

"The best CMS plugin is the one that ships as a text file your client can email you."

— Probably not Andy Miller, but he'd agree in spirit
